The orientation of the translated component with respect to the second point will be identical to that of the original component with respect to the first point. First Point Second Point arc center arc center. Translate Translate provides a means to move a component a delta value with respect to the reposition coordinate system.

Translated components maintain the original orientation relative to other parts. Axis of Component Rotation being repositioned. Reference Point ZC. YC XC. This option allows components to be rotated about a defined vector which is not necessarily parallel to the ZC axis.

After editing, the work part must be saved to keep the modifications. Higher level assemblies will not be saved even if they were modified. TIP File"Save All saves all loaded parts in the session that have been modified regardless of the work part designation. Activity 1 - Adding and Repositioning a Component In this activity components will be added to an assembly. These components will then be repositioned to the proper locations. The Load Options must be set properly before loading the assembly.

The test stand is the part that the circuit board fits in for assembly and circuitry testing. The illustration below shows how the mounting block is to be oriented to the circuit board. The next step will direct you through the repositioning of the mounting block. Step 5 Add a new component to the subassembly. Verify the component name in the Status line. It may be necessary to rotate and zoom in on the view so that the proper arc centers are selected Remember: Holding down MB2 and dragging the cursor on the graphic window rotates the view.

Select this arc center as the First point. You already own this part file, so this step is not necessary. Step 8 Save and close the assembly. A warning message appears. Currently the load options are set to look for the component parts in the same directory as the assembly part file.

Your assembly file is saved in your home directory while the component parts are stored in the course parts directory. Assemblies provides the ability to design in context. Added and repositioned a component in an assembly. The Unigraphics assembly is a file containing stored links to the part files that are pieces of the assembly. The geometry that defines the piece parts of the assembly resides in the original part file only, there is no duplication in the assembly file.

A link in the assembly file is referred to as a component object. A component object stores information about the piece part such as its location, attributes, origin, orientation, permissions, degree of display, and its relationship to other parts. Applying the Master Model Concept in a Drafting situation is simply the creation of an assembly consisting of one component part. It is valuable as a means of promoting concurrent engineering.

The person responsible for the design of a part is not the same person responsible for all of the downstream applications performed on the part. These downstream applications may include drafting, manufacturing, analysis, etc.

The Master Model Concept is also valuable in protecting the design intent of the part from inadvertent corruption by a downstream user. The downstream user will have write privileges to the assembly file, but only read privileges to the model. The solid model is referenced for the application work, but the downstream user will not have the ability to change it.

Implementing Master Model theory allows diverse yet dependent design processes to access the same master geometry during development. Therefore, the entire part creation process becomes more efficient allowing many disciplines to work at the same time and allowing master model edits to be automatically updated in non-master parts. The power of implementing a Master Model is that the independent design processes are dependent on the same master geometry during development.

Each application uses a separate assembly file. When the Master Model is revised, the other applications will automatically update with minimal or no associativity loss. The design intent of the various design applications can be maintained through protection of the Master Model. Manufacturing engineers have the need to design fixture devices, define machining operations, and designate cutter tools and save this data in their models.

Contains manufacturing data and a component object which references master model part. The manufacturing engineer has ownership of the assembly file without necessarily having write access to the master model which is owned by the designer.

Both dimensions have been rounded from the model dimensions to two decimal places. Corner Radius. This part contains the Master Model definition. Place the cursor over the solid body. Pass the cursor over the numbers in the QuickPick window until the solid body is highlighted, then select it. An information window appears with information regarding the solid, its owning part, and confirmation that it is a component.

Step 9 Edit the blend on the inside of the spool cavity. Confirm the selection with OK. Step 12 Zoom in on section A-A again to see the changes to the master model reflected on the drawing. Users can access whatever they want, whenever they want with full confidence that no data or revision work can be lost without active confirmation by the users.

If the solid is updated, the views will also update. Full color is the default setting. In this mode objects are displayed in the color that they appear in the modeling application and the background is the color set by the Preferences"Visualization"Color Pallet"Edit Background dialog. Monochrome Display provides a means for a drawing to appear more like an actual drawing black-on-white.

The foreground and background colors may be set in this dialog. Show Widths may also be set here but only applies to drawings. When Monochrome Display is toggled off, drawings will be displayed in full color. The Drawing"Edit option may be chosen to change the creation parameters of a current drawing such as name, size, scale, units of measure, or projection angle.

The current state of the displayed drawing affects the edit options available. The following are things to be aware of:. However, if the drawing is edited to a size so small that a view falls entirely outside the boundary of the drawing, an error message will appear. Activity 1 - Editing a Drawing In this activity, the current drawing name, size and scale will be modified.

NOTE: In order to save the drawing information or edits, the part file must be saved. The first view added is based on the view orientation selected from the list box in the upper portion of the Add View dialog. Once this view is added to the drawing, it determines scale, layer settings, as well as the orthographic space and alignment of subsequent orthographic views. It also establishes the part orientation on the drawing.

Viewpoint Selection List. When toggled ON, this option automatically creates linear, cylindrical, and bolt circle centerlines with a circular instance set for views where the hole or pin axis is perpendicular or parallel to the plane of the drawing view.

You can use the Drawing"Remove View option to remove one or more views from a drawing. Once a view is removed from a drawing, all drafting objects or view modifications associated to that view are deleted.

Activity 2 - Adding a View to a Drawing In this activity, a view will be added to the drawing previously created. The Top viewpoint is the default view orientation. Any one of the listed viewpoints could be imported as the first view on the face of the drawing. View bounds are ghosted to assist in view placement. If there is a need to reposition the view after placement, choose the Move button from the dialog box, then specify a new view center.

Note that the Top viewpoint of the part as it relates to model space is being placed on the drawing such that it depicts an orthographic front view of the part. This flexibility assures that the drawing views necessary to depict the part may be placed on the drawing independent of the orientation of the part in model space.

Orthographic View. The location of the cursor relative to the base view determines the Orthographic view projection from the parent view. The View Display dialog box may be used to define and edit the display of such things as hidden lines, silhouettes, smooth edges, etc.. The View Display dialog box may be used to preset preferences for subsequent views added to the drawing, or this dialog box may be used to edit the settings of existing drawing views.

To edit the View Display preferences of an existing view, select the view s from the drawing, or choose the view s from the selection box. When each View Option Button is selected the appropriate choices for the option are displayed in this area. If the Hidden Line option is toggled Off, Hidden Line removal is not performed and all hidden lines in the view will appear.

If the Hidden Line option is toggled On, the color, font and width of the hidden line display is determined by the settings in the Color, Font, and Width option menus. Smooth edges are those edges that their adjacent faces have the same surface tangent at the edge where they meet. If the Smooth Edges option is toggled to the On position, the Color, Font and Width option menus may be used to determine the appearance of the smooth edges.

The End Gaps option may be used to vary the edge intersection appearance. The appearance of visible objects may be determined by using the Color, Font, and Width option menus. Virtual Intersections are the theoretical sharp intersections that occur where blended faces would intersect, where the display of smooth edges may cause confusion. If the Virtual Intersections option is toggled to the On position, the Color, Font and Width option menus may be used to determine the appearance of the virtual intersection display.

The Extracted Edges option allows the edges of an assembly to be shown without loading all of the component parts. Edges are extracted at the component level and remain associative to the component. The Automatic Update option may be used to control whether a drawing view is updated after the model has been changed.

If Automatic Update is turned on, hidden lines, smooth edges, and silhouettes are updated after changes are made to the model. If Automatic Update is toggled off, these edges are not updated. This option does not affect section views, or detail views made from section views.

These views always automatically update after the model is changed. Activity 3 - Setting View Display Preferences In this activity, you will practice setting the view display preferences. Step 2 Change the view display preferences for the imported view added to the drawing. Step 3 Save and close the part file. The Utility Symbols option creates various centerlines, offset center points, target points, and intersection symbols.

The Utility Symbols dialog box consists of four distinct areas: symbol icons, position options, symbol display parameters and preference options. Symbol Display Parameters control the creation of each utility symbol as it is placed. These parameters may also be used to modify existing drafting symbols.

Symbol Icons. Point Position Options. Symbol Display Parameters. This option automatically creates centerlines in any existing view s where the hole or pin axis is perpendicular or parallel to the plane of the drawing view.

If a series of holes in a circle bolt hole circle are not a circular instance set, then a linear centerline is created for each hole. A utility symbol's placement is controlled by a position on an object. The system will automatically size the symbol components to the objects used to create it, based upon the symbol display parameters.

The symbols may be selected at any position. The point position options allow a centerline associated to objects other than cylinders to be created. Activity 4 - Creating a Cylindrical Centerline In this activity, cylindrical centerlines will be created using both the arc center and cylindrical face options.

Repeat for the other two pairs of positions. Select this pair of edges, confirming your selections if needed. Step 4 Create a centerline symbol using the Cylindrical Face option. The indicated end points are projected to the axis of the cylindrical face, and two drafting points are created that are associated to the selected face. Step 5 Repeat the procedure for the two counterbored holes in the orthographic view. This time, the face selection will need to be confirmed, as the system will select the main, or outside face first.

This face will highlight in the view that the face was selected, as well as in the adjacent view. Select this face. Notice how you did not have to select the endpoints for this centerline, this is because Multiple Centerlines was turned on. The completed centerlines are shown below. Step 6 Create Automatic Centerlines. The various dimensions types may be accessed two different ways. The other way is by choosing the dimension from the customizable Dimension toolbar. Whenever a dimension type is selected a dimension dialog specific to that type of dimension is displayed.

Line and point type definitions for Cylindrical Point type dimensions. Vector definitions for Angular dimensions Annotation editor for appended text. The Vector Definitions options are only available when creating an angular dimension.

An angle dimension is the measurement between two vectors. The various options provide a means of defining the vectors. These options are only available when creating a cylindrical dimension. The various options provide a means of defining the lines or points that the dimension measures. The Dimensions dialog box contains options that control the display and placement of dimensions.

These local preference settings may be changed with each dimension created. Text or symbols may be added to dimensions via the Annotation Editor and toggling on Use Appended Text.

One or all four positions may be used on the same dimension. NOTE: If the position arrow displays solid, that is an indicator that text is present and will be displayed in the dimension.

If that text is not desired, select the position button and delete the text. Any text entered in the appended text fields will continue to be added to any new dimensions created unless the Use Appended Text option is toggled off. The Precision button activates the Dimension Precision dialog box which is used to independently control the precision of both dimension values and tolerance values.

Both single Primary and dual Secondary dimensional precision is supported. If the dimension display format is set to fractional values instead of decimal values then the Dimension Precision dialog box will show fractional values for the nominal precision option. This pull down is active when using dual dimensions. For decimal For fractional precision precision. Example: X. XXX Example: X. The display of tolerance values may be controlled using the Tolerance Types shown below. The Tolerance Value fields are active in respect to the units button, Inches or Millimeters, that has been selected.

Any value entered in these fields will be interpreted as positive unless a negative - value is specified. Limits are calculated by adding the positive tolerance value to the dimension value for the upper limit of 5. Displays a basic dimension enclosed in a rectangular box around the dimension.

No tolerance values are displayed. Dimensions placement on the drawing may be controlled using the options shown below. Manual Placement, Arrows Out. Auto placement automatically centers the dimension between the extension lines if space allows, or moves the text outside the extension lines if necessary.

Auto placement also controls whether the leader lines come from left or right. When using the Manual Placement, Arrows In or Arrows Out options, the dimension is placed at the cursor location specified. The leader line placement is controlled manually using the Leader From option.

The display of arrow lines and extension lines for dimensions may be controlled using the Arrow Line Display and Extension Line Display options shown below. The dimension leader direction may be controlled by selecting one of the three leader options. The leader option may be set prior to creating the dimension or changed during placement of the dimension. Example: Left R 2. Text justification may be controlled using the Horizontal and Vertical Justification options. In addition to the Dimension Local Preferences, there are Global Preferences governing drafting views and entities.

Activity 5 - Creating Dimensions In this activity, several dimensions will be created using various local settings on the Dimensions dialog. NOTE: It will be necessary to set Dimension local preference settings and the Global preferences to create each of the following dimensions. Choose OK. Step 4 Create a Vertical dimension. Step 5 Create a Cylindrical dimension. Any of these symbols can be placed on the drawing with a leader or as a standalone note without a leader. Text Entry Window.

Preview Window. Symbol Display and Text Preference Options. Placement Options. As text and symbols are entered, the text and control characters appear within the Text Entry Window. In this window the formatting options available within the Tool Bar may be used to customize the appearance of the text. The preview window displays the text as it will appear when it is placed on the drawing. The Tool Bar contains several buttons that allow various text formatting operations to be performed.

TIP To reveal the function of any button, hold the cursor over the icon until the name of the button appears. Notes and labels may be placed on the drawing either with or without a leader line, depending on the placement option chosen.

Create with Create without Leader Leader. When the Create without Leader option is selected, the Origin Tool dialog box is displayed. This dialog box allows you to specify the placement and alignment method for the text. To create text with a leader line, choose the button to display the Create Leader dialog box. This dialog box allows one or more leaders to be specified as well as the display characteristics of each leader. Once all selections are made for the Create Leader dialog box, choosing OK will proceed to the Place Annotation dialog box discussed earlier.

Drafting objects may be created with more than one leader by selecting the New Leader button anytime during the leader creation process. The default placement method is Drag, but the Point Constructor option may be used to tie the text location to a control point, arc center, or intersection point.

Text may also be aligned either horizontally or vertically with an existing drafting object using the Align Text option. The Offset Distance option may be used to indicate an origin position offset from an existing drafting object. A horizontal and vertical distance is given as multiples of the current character size when using the Offset Character option. Text may be edited in a previously created note or label by selecting it from the drawing.

When a note or label is selected, it is captured in the Text Entry Window so that changes may be made. When editing is completed, simply choose the Apply button to accept and display the changes on the drawing. The Annotation Preferences dialog will appear and the following types of preferences may be edited. Center Justify Right Justify. Select this edge. Views and dimensions that are placed on a drawing are associative to the solid model and update when changes are made to the model.

Reference Features are theoretically infinite in size, but the display is limited to a size slightly larger than that of the solid model. Reference Features may be created relative to an existing solid model or fixed in model space. This lesson will only discuss relative datum planes.

In the case where a hole must pierce a cylinder to a certain depth from the outside of the cylinder, construction tools are necessary. These tools are needed because the hole feature requires a planar placement face for creation rather than the cylindrical face of the base solid.

The amount of control desired over placement of a feature sometimes dictates the number of reference features required. Two examples below show a hole in the side of a cylinder, normal to the axis of the cylinder. The example on the right requires an additional datum plane to position the hole perpendicular to the slot.

Plane 2A Plane 2B parameter. In example A above, Plane 1A defines a position through the cylinder axis, while Plane 2A defines a placement plane that is tangent to the cylindrical face and perpendicular to Plane 1A. This allows the hole to be placed on the tangent datum and be relative to both the cylinder and Plane 1A. Datum Plane reference features are accessible by choosing Insert"Form Feature"Datum Plane from the menu bar while in the Modeling application.

Relative datum planes are constrained associated to other geometric objects. A constraint is a restriction on a datum that positions it relative to some existing plane, face, or feature. Relative datum planes are created by selecting an existing object. The constraint type is determined inferred by the objects selected. Generally, whatever is necessary to describe the relationship of the plane to other objects determines the constraint type s to be used. One, two, or three constraints may be necessary.

Simply selecting the objects will present the applicable constraint types. The possible combinations of selections are shown on the next page. The Triple Constraint method is inferred by selecting three points on a single solid body. The Datum Plane is associative to the body and constrained to the selected points. Only Endpoints and Midpoints on linear edges are selectable.

The Datum Plane Dialog may be used to create datum planes that are more specific than those you can create with the Inferred method.

Values between 0 zero and 1 define locations on the selected edge or curve. Values less than 0 zero or greater than 1 may also be used. The datum planes created are shown below. Datum plane 1 Datum plane 2. Step 3 Create a Datum Plane Offset at a distance of 1 inch above the upper face of the block. Pick this top face. The vector displays the positive offset direction. Third Point Second Point. The datum plane is created and positioned through the three selected points.

The relationship of this datum plane through the points will remain if the block parameters are changed. Step 5 Create the third datum plane midway between the left and right faces. The datum plane is created and located at the center of the part and is parallel to the faces selected.

Step 6 Edit the block to verify the parametric relationship of the datum planes to the block. The revised values are displayed in the graphics area. Again a dialog box displays options to edit the feature.
