Simplify Boundary

When model geometry is imported into Slide from other sources (e.g. dxf files) it is quite common that boundaries are defined by an unnecessarily large number of vertices. This may occur for a number of reasons, e.g. manual digitizing procedures, creation of 2D sections from 3D geometry, etc. When boundaries have an excessive number of vertices, this can lead to modeling, meshing or analysis problems (e.g. difficulty editing boundaries, poor quality meshes, increased compute times, etc).

The Simplify Boundary option allows you to reduce the number of vertices on a boundary, according to a user-defined criterion, so that the new boundary has fewer vertices but still adequately defines the model geometry.

To use Simplify Boundary:

  1. Select Simplify Boundary from the Boundaries menu.

  2. Use the mouse to select the boundaries you would like to simplify. NOTE:

  1. When you are finished selecting, press Enter or right-click and select Done Selection.

  2. You will see the Simplify Boundary dialog. There are two options for defining the degree of simplification:

  1. Choose the desired criterion and enter a value of percentage or distance. You can select the Apply button in the dialog to see the results without closing the dialog. When you are finished, select OK and the selected boundary(s) will be simplified according to your input.
