Reference Model

The name of the imported original model will be displayed in the panel as shown below.

You can import models in STL, STP, STEP, and OBJ formats.

Click on the name of the reference model in the panel, and the vertices of the model will be displayed in the editing workspace, as shown below.

Click on the icon next to the model name to display or hide the body of the model. The figure below is an example of displaying all the vertices and no facets of the model.

Resource Tree

As shown below, all the created geometric solids and convex hulls will be displayed in this panel, and you can adjust the transparency of them.

Editing Workspace

The editing workspace is shown below. You can edit and view the edited model here.

• Scroll up and down with the mouse to zoom in and out in the editing workspace.

• Click and hold the left button on the mouse and drag in any direction to rotate the view.

• Click and hold the scroll wheel and drag in any direction to pan the view.

• Right click the mouse and you can switch the view by selecting a view in the context menu as shown below.
