      TIG,

      The main problem with have with the SU API is that there is no Bulk methods to work on a set of elements for Smoothing, Reversing, Orienting, etc.... (whereas these methods exist in the natural GUI). As a result, doing it by program results in long response time, even longer that to generate the basic mesh geometry. We could ask the SU Google Team to add these methods in a next version, but you know there is no guarantee.

      For face orientation, my plan is to calculate the orientation in the algorithm itself (based on the ordering of points in the Geom::PolygonMesh construction).

      For the time being, I consider this is not a critical issue for the user, because s/he can always orient, reverse and smoothen instantly the face mesh, even complex, via the native SU GUI (of course, Orient Face should be more known). I assume that users need Curviloft occasionally and do not need to generate 20 meshes by minutes.

        I did this with DC and loft by splines.
        After making transformed copies of only two profiles, then I launched loft by splines.
        Here is my other post which contains more images and information.

        Thanks for your efforts I could go further in my DC investigation. 😄

          Hi Fredo

          I just tried the Skinning feature.
          At first I thought it failed to create the mesh - but then I realised it had created it, just not in the current context. I was working on some curves inside a component with Hide Rest of Model enabled - so I did not see the mesh getting created.

            Currently the mesh is created as a Group at the first level of the model. That's a small bug.
            Anyway, I will probably improve this part, in particular the possibility to use existing groups, if you build the mesh piece by piece

              It's quite straightforward to make your new mesh-group in the same 'context' as the selected curve edge[0], in the form entities=edge.parent.entities group=entities.add_group()
              Then the 'group' for the new mesh will be in the same 'context' as the curve's 'edge'... 🤓

                TIG,

                The bug is simply that I used model.enntities instead of model.active_entities, which is the current working context.

                I cannot rely on edges context, because Curviloft can actually 'borrow' contours from Edges that can be within different groups or components.

                  Got you...
                  So just add the active_ to entities and it works !!! 😒

                  Line#198 in CurviloftGeometry.rb
                  @top_group = @model.**active_**entities.add_group

                        Wow, that's pretty cool. 👍

                        Who would think that Sketchup could do such a thing with a few click of the mouse.

                                    You have a great imagination, and I assume your knowledge is less limited than many 😄 👍 👍

                                    I notice in the SKup captures that the geometry is coincident but not intersecting. I did not realize that a render app would tolerate this?

                                    By the way, which render app is it?

                                    I take the slow, deliberate approach in my aimless wandering.

                                        Hi mitcorb,

                                        I use Kerkythea. With Kerkythea I have the most experience. I consider myself still a beginner as regards to rendering. I would recommend anyone to begin with Kerkythea and to study the program thoroughly. This is a good basis for understanding other rendering programs.

                                          I usually start trying to construct a basic form. Then you can play with the spline Methods. Then make a group and copy them and connect them several times. Make it a group again and use again rotate copy. It is very easy. The result is mostly interesting geometric objects. Useless but nice to see.

                                          I would be very interested in what ideas others user have. Has someone already used it for architectural purposes?
