Generate Patches

This command allows you to generate CAD surfaces from a mesh and a polyline network. The surface is made of patches fitted onto the mesh.

Requirements

Select the mesh and a polyline network previously designed (polylines and/or set of polylines) and launch the command.

1. When you open the command, a pre-computation is launched. A shell composed of CAD curves and faces is computed. All the computed faces will be fitted on the selected mesh.

2. You can modify the deviation of the computed curves: select one curve in the scene, and move the slider in order to choose to be closer or smoother.

3. Inside the Results section, you can see:

   • The Standard deviation for curves

   • The Max deviation for curves, corresponding to the curve having the maximum standard deviation

   • The Standard deviation for faces

   • The Max deviation for faces, corresponding to the face having the maximum standard deviation

Tips & Tricks

A polyline network can be obtained through different workflows:

• automatically with the command Create Network

• manually using all the commands creating sections on a mesh. For example, Free Hand Section, Single Breaking Line or Projected Polyline
