Title: Space Loop (Fixed)
Post by: steve on July 14, 2012, 12:51:49 am

Hello,

I have been seeing problems when trying to use the "Space Loop". I have found a very simple example that is repeatable.


Plane of 14 x 14, have moved 2 vertex on outer edges.

Space loop OK

Plane 14 X 35, have moved 2 vertex on outer edges.

Space loop does not work in one direction.

It appears that on some meshes, one loop direction(any loop in the same direction) will no longer "Space loop", while the other direction does "Space loop" correctly.

When you have time, could you please check.

Thanks,

-Steve

The implementation of the Space Loop is expecting you to have selection loops that don't intersect each other. In the example you showed here you have four loops branching from one vertex, how about if it is 3, 5 or more branches. One general solution I can think of is to cheat each loops from the intersecting vertex as a sperate loop for Space Loop operation, but that may not what you expect.

It is the same problem if I only select the one loop (sorry, I should of explained that). In the above example, if I select any of the edge loops that run down the 35 edges, the "space loop" does not work.

Here is an example.

"Space loop" does not work on single edge loop.

I am also still curious as to why the "space loop" does not work on closed edge loops. In the Help file, it does show a selection of closed edge loops as an example, but it does not work. For simple example, if you select an edge loop around a cylinder, nothing happens when using "space loop".

Fixed. It is ok to have selected lines crossing each other.
