The Collapse Curve – All Augmented Points command allows you to create corners with XirusCAD. The tangent and curvature values at the selected point(s) will be set to 0.
You can call the Collapse Curve – All Augmented Points command from the XirusCAD menu, from the XirusCAD Toolbar or from the command line. Select the points on your XirusCAD curve. All the augmented quantities of these points will be collapsed. This means that the tangent and curvature values at those points will be set to 0.
In the video, the Collapse Curve – All Augmented Points command is found under a different XirusCAD menu item.
