Emboss Swept

Introduction

This topic will explain the Emboss Swept, describe where to find it, the options found in it, and will provide links to related topics.

Emboss Swept

The Emboss Swept feature creates an emboss by sweeping a cross section along open or closed geometry chains. The chains (feature geometry) can be any combination of lines, arcs, and splines and they must be 2D geometry drawn in the XY plane. The cross section is swept along the entire length of the open or closed feature geometry.

Navigation

To create an Emboss Swept feature:

 

• In the BobART tab, right-click Emboss Model, and click Emboss Swept.

 

The Emboss dialog displays.

Parameters

Quick Access

 

• Apply - regenerates the canvas to display the current parameters of the feature.
  
  

• OK - regenerates the canvas to display the current parameters of the feature and exits the dialog.
  
  

• Cancel - discards the updates to the parameters and exits the dialog.
  
  

• Show or Hide all images in the graphics area - This option will show all hidden images in the graphics area. This same option will hide all images in the graphics area, besides the one being worked on for those features which utilize a loaded image.
  
  

• Show or Hide the embossed BobART model in the graphics area - This option will show the hidden canvas in the graphics area. This same option will hide the visible canvas in the graphics area.

 

Attributes

 

• Name- indicates the feature name that displays in the BobART tree. By default, it is automatically named by the feature type and number. Note that you cannot use the hyphen (-) character with spaces around it, as this is reserved for the automatic naming and will be removed. You can however use it without spaces, for example, Emboss-Body).
  
  
• Color - click the drop down to select a Theme Color or Standard Color, or click More Colors to open the Select Color dialog. Select the desired color for the feature, and click OK to set the color, or Cancel to exit the dialog. (The default color is set using the Solids color of the Settings Part/Settings Default dialog box.)

The list box will list the entities currently selected for the function.

 

Cross-Section

This section contains all of the parameters that shape or appearance of the emboss in Z. To learn more, view the Emboss Cross Sections help topic.

 

• Convex Arc - This cross-section type creates a raised arc in the model using the following parameters.
  
  
• Radius - sets the distance from the center of the arc to the edge of the arc.
  
  
• Start Angle - sets where the arc begins and is tangent to adjacent surfaces in the model.
  
  
• End Angle - sets where the arc stops and is tangent to adjacent surfaces in the model.

 

Note: If the Start Angle is greater than the End Angle the resulting surface is concave and the radius does not appear in the model. The angles should be within a sweep of 90 degrees, that is, neither value should exceed 90.

 

• Concave Arc - This cross-section type creates a sunken or depressed arc in the model using the following parameters.
  
  
• Radius - sets the distance from the center of the arc to the edge of the arc.
  
  
• Start Angle - sets where the arc begins and is tangent to adjacent surfaces in the model.
  
  
• End Angle - sets where the arc stops and is tangent to adjacent surfaces in the model.

 

• Line - This cross-section type creates an angled wall on the model using the following parameters.
  
  
  • Height - sets the distance from the bottom of the Slope Angle to the top of the Slope Angle. If looking at the results of this operation as a right triangle, the height indicates the length of a leg and not the length of the hypotenuse.
    
    
  • Slope Angle - sets the angle of the resulting surfaces, relative to the stock of the model.
    
    
• Convex Ellipse - This cross-section type creates a raised radial surface on the model using the following parameters.
  
  
• Major Axis - sets the horizontal length of the ellipse.
  
  
• Minor Axis - sets the height of the surface created by the operation.
  
  

 

• Concave Ellipse - This cross-section type creates a sunken or depressed radial surface in the model using the following parameters.
  
  
• Major Axis - sets the horizontal length of the ellipse.
  
  
• Minor Axis - sets the height of the surface created by the operation.
  
  

 

• Spline - This cross-section type creates a contour using three control points as follows.
  
  
  • Point 1(X-Y) - sets the distance from the base geometry to the first control point in X/Y.
    
    
  • Point 1(Z) - sets the distance from the stock to the first control point of the contour in Z.
    
    
  • Point 2(X-Y) - sets the distance from the base geometry to the second control point of the contour in X/Y.
    
    
  • Point 2(Z) - sets the distance from the stock to the second control point of the contour in Z.
    
    
  • Point 3(X-Y) - sets the distance from the base  geometry to the third control point of the contour in X/Y.
    
    
  • Point 3(Z) - sets the distance from the stock to the third control point of the contour in Z.
    
    
• Custom Cross Section
  In addition to the six predefined cross-section shapes, you can select custom cross-section geometry. The custom cross section must be an open shape and it must be drawn (flat) in the XY plane. The cross section can be drawn anywhere in the graphics area, as long as it is drawn in the XY plane. The open shape can include lines, arcs, and splines.
  
  Because embossed models cannot have undercut areas, any part of a custom cross section that would result in an undercut area results in a vertical wall. What this means is that although there are some limitations on the shape of the custom cross section, you can draw any open shape, and the software automatically uses as much of the shape as possible. If you cannot create the desired result, you may need to redraw the cross section.
  
  To assign a custom cross section:
  
  
  • In the Cross Section group of the emboss feature dialog box, select Custom.
    
    
  • In the BobART tree, right-click Cross Section Geometry, and click Re/Select.
    
    
  • In the graphics area, select the cross section geometry, and confirm the selection.
    
    
  • Regenerate the model.

 

Fast Edit

 

• X-Y Scale - scales the cross section geometry that is used to create the feature. A value of 0.5 scales the cross section to one-half (50%) of the original size in the X- and Y-axes.
  
  
• Z Scale - changes the height of the resulting surface in relation to the Z-axis. A value of 1.0 is equal to 100% and results in no scaling.
  
  
• Base Height - creates a vertical wall that extends from the stock, to the beginning (bottom) of the embossed model. In other words, this adds a wall to the base of the model.

 

• OK - accepts any changes and closes the dialog. (The first time you click OK, the feature is created and added to the BobART tree.)
  
  
• Cancel - cancels the creation of the feature (the first time that the dialog box displays). When editing the feature, this cancels any changes and closes the dialog.

 

 

After defining the parameters, you use the Emboss Features in the BobART Tree to edit the feature as needed.

The Emboss Feature in the BobART Tree

When you finish defining the feature parameters and click OK, the feature is added to the BobART tree. You right-click each feature item in the tree to access a shortcut menu.

 

The Feature Shortcut Menus

 

Emboss Swept

Right-click this item to access the following commands.

• Edit - opens the Feature dialog for you to modify the feature parameters.
• Delete - removes the feature from the tree. Regenerate to view the change in the model.
• Suppress/Unsuppress - is used to remove the feature from the model or to restore a suppressed feature. To update the model, Regenerate.
• Save As Component/STL - is used to save the feature as a component or .stl file. This saves the individual feature and not the entire model. The STL Save Option dialog box is displayed for you to set the tolerance. Next, the Save As dialog is displayed for you to select a location, name the file, and save it. The component can be used to create an Emboss from Component feature.

 

Geometry

Right-click this item to access the following commands.

• Re/Select -enables selection mode for you to select geometry that is used to create the feature. To confirm your selections, click OK.

• Remove - removes any geometry assigned to the feature.

 

Cross-Section Geometry
