Emboss Cross Sections

In this Topic Show

Introduction

The Cross Section of the Emboss Regular, Emboss Swept, and Emboss Texture from Weave features defines the shape of the emboss feature in Z. The cross section is what you would see in a sectional view of the model. BobART contains six predefined cross-section types, and BobART Pro now includes the option to select custom cross-section geometry. The cross-section types and related parameters are explained next.

 


TIP:   When defining the Cross Section, you can drag the handles (red squares) of the cross-section geometry in the preview. This method automatically updates some of the available parameter values.


Convex Arc

This cross-section type creates a raised arc in the model using the following parameters.


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.

Line

This cross-section type creates an angled wall on the model using the following parameters.

Convex Ellipse

This cross-section type creates a raised radial surface on the model using the following parameters.

Concave Ellipse

This cross-section type creates a sunken or depressed radial surface in the model using the following parameters.

Spline

This cross-section type creates a contour using three control points as follows.

Custom Cross Section

New to BobART Pro for V25, you can now 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 workspace, 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:

 

 

 

 

 

 

The following images show the result of using the same feature geometry and custom cross section for each of the three supported feature types.
