Spiral

In the new version of T-FLEX CAD, the operation of creating a spiral has been updated.

The new version works on the basis of a spiral 3D path (see Helix 3D Path), so the interface and basic features are identical.

Below are the operation parameters windows in T-FLEX CAD 16 and T-FLEX CAD 17, respectively:

Updated the Profile group. You can select 3D profiles, paths, edges, or faces.

Multiple edge selection is available.

Fixing points define the orientation of the profile. The first point is aligned with the beginning of the spiral path.

The Scale option is an analogue of smooth from version 16. The scale can be set as a constant. A value other than 1 resizes the spiral along its entire length.

You can select graphs as a scale. A Polyline graph with two points scales linearly from the beginning to the end of the entire length:

A Polyline graph with more than 2 points changes the scale linearly:

The Cubic Spline graph scales smoothly, according to the graph, along its entire length:
