Unwrap Segments: Unwrap the selected segments into 2D Parts.

Select segment by edges tool

...

:   (Available in TurboCAD Pro Platinum only)

To activate the tool:

1. Activate UV mapping tools
2. Select the Image
3. Select a TC surface
4. Choose command Select “Create segment by edges…” (Fig. 1).edges…” 

Figure 1. Start creating segments by edges

After that user should , select a closed edge loop. For this purpose there are two possibilities:

1. Manual . To select - Select the edge loop manually by clicking one edge after the other. At every moment all All selected edges should be connected. It This means that user you can only select only those edges which have common vertices with those already selected. And there is another limitation: in Another limitation for each vertex there can only be two edges from the selected edge loop – it is a way of dealing with this prevents self-intersections.
2. 2.      Mixed manual and automatic. If user you have already have selected a few edges (, but not closed), he you can try to close edge loop automatically by using command “Close selecting  Close current selected edge loop…” (Fig.2). In this case loop… The program will try to find the shortest path between the ends of the current currently selected edges and connect them.

For the each closed edge loop it is possible to create two segments

; One from internal facets,

the other from the external facets. The algorithm

will automatically choose one of these domains. If the algorithm choose the opposite domain from the one you wanted select Invert created segment… which will invert the selection to the alternate facets.
