@panixia said in [Plugin] QuadFaceTools:
There's also a problem with unwelded UV islands (the UV are in the right places but actually each quad has cuts/seams at all edges).
It's not another problem; it's the same one. The triangulated quads in SketchUp are being exported with duplicated faces. These duplicated faces are the ones you see unwelded in RizomUV. Blender usually fixes this problem just by opening the OBJ files.
I think I've figured out what is wrong with the OBJ files generated by the OBJ Exporter from QFT and why sometimes they don't work properly in other software such as RizomUV or Substance Painter.
I have reported this issue on the GitHub page for QFT, but I believe it could be helpful to someone if I also post it here, especially since a solution to the problem is provided at the end of the post.
I've been struggling with this issue for quite some time, but since I didn't fully understand what was happening, I couldn't provide useful feedback. Recently, however, I've been able to clearly identify the problem and even managed to resolve it using Meshlab, a free software to clean and improve 3D models.
The OBJ files generated with the OBJ exporter from QuadFaceTools have duplicated faces in those quads that have been triangulated in SketchUp.
When you open an OBJ file created with this exporter, software like Blender automatically resolves this issue. However, other software such as Substance Painter or RizomUV may struggle to handle these duplicates correctly.
I believe this issue is the root cause of these issues:
I created a simple SketchUp model with just two cubes:
Each cube have 24 quads. The triangulated one (on the left) is a component called 'cube_t', and the other one (on the right) is also a component called 'cube_q'. I exported them separately using the OBJ exporter from QFT to identify the problem, using the following settings:
After exporting, I obtained these two files: cube_q.obj and cube_t.obj.
Next, I used the free open-source software Meshlab to check the number of faces in each OBJ file. After opening Meshlab, navigate to File > Import Mesh and select cube_q.obj.
For the first mesh ('0'), you can see there are 48 faces (24 front + 24 back), as expected. However, when I added cube_t.obj using File > Import Mesh, for the second mesh ('1'), there were 96 faces, TWICE (!) the expected number for the same number of quads.
This issue causes Substance Painter to struggle with generating proper automated UVs, while RizomUV fails to correctly utilize OBJ files exported from QFT's OBJ exporter.
Until a potential solution is considered within QFT's OBJ exporter itself, here's a simple and practical solution using MeshLab:
Select the problematic mesh from the Layer Dialog.
Go to Filters > Cleaning and Repairing > Remove Duplicated Faces.
After completing the previous step, verify that the number of faces in cube_t.obj is 48. If correct, proceed to File > Export Mesh and save the corrected file as new_cube_t.obj (or a similar name).
If you try to open this corrected file in RizomUV or Substance Painter (using the auto-UV features), it should work smoothly.
@L-i-am Great news! In the last months, I've been doing some renders with Lumen so it's really nice to have Twinmotion for free.

ok, that did it - adding 3 posts enabled the signature and site link options.
Good to know, thank you!
@Box said in NEW Forum Software Issues:
@alsomar Click your Avatar, top right and choose Edit Profile then scroll down to Signature and then to save changes.
I don't have this option now, I think I had it in the old syle. Anyway, thank you for answering.
@Rich-O-Brien said in NEW Forum Software Issues:
@alsomar I believe you maybe behind the reputation system this newer forum uses.
So maybe @Box suggestion is unavailable to you. If you are unable to change it let me know and I'll see what we can do.
I'd be interested to know if you are able or not.
The option doesn't exist in my profile, so I gues I have a bad reputation 
Hi there! I like the new look, but I can't find where to change my signature.

if you'd apply summon extruder on a damaged cylinder it'd reverse the back of the faces (area A) on the cylinder's back - seen on area B (reversed).
About face orientation: FaceUp orients the face to the viewer point of view. That means it reverses the back faces of the cylinder. You should have in mind this extension is meant made easier the workflow with 2D dwg files,
@rv1974 said:
Also, is it possible to implement faces as components (insted of groups) with axes aligned to the face plane. Currently they are aligned to the global UCS which is not good (C).
I don't think I can manage to convert the faces into components. An algorithm to identify faces with same area, sizes and different orientations and positions goes far beyond my knowledge. On the other hand, groups aligned with the face (or the solid group) can be a nice feature to add.
Thank you for your feedback!
@rv1974 said:
Oh summon+extruder with extrude 0 is especially useful
Could you make this command to remember the last extrude value (say 0)?
Thank you
Well, that's a bug! FaceUp can remember last length except 0. Thank you for the heads up! I'll try to fix it.
Hi there, Rich! Thank you for your kind words

Random heights between a min/max value or range would be great.
During the initial stages of FaceUp's design, I considered this feature, and it would indeed be a nice addition to the extension. I'll definitely give it a try in the future.
@rich o brien said:
Also, if faces are separated by a soft/smooth edge, then treat those faces as a surface and create an extrusion from that.
Actually, there was an alpha build of FaceUp that included a feature like this, but it didn't work out very well (I'm not exactly a top-notch developer, hehe). However, I can envision a future version of FaceUp incorporating this feature.
@rv1974 said:
I know at least 3 or 4 "make faces" plugins and there's also "loose to groups" and JPP, but its nice to see
other alternatives and, more important - new plugin creators
Hi there, thank your for leaving a comment.
I know there's a bunch of extensions creating faces from edges (Eneroth Face Creator, a feature from Tools on surface by Fredo6, MakeFaces, etc.), but I needed something slightly different. Summon Faces creates faces oriented to the viewer. That was the only way to make Summon + Extruder work fine:
Hi there! After years of using and benefiting from the vast array of extensions on SketchUcation, I'm really happy to share my first upload to the PluginStore. This extension was designed to improve my own workflow with DWG files. I hope it proves useful to someone else.
FaceUp is a SketchUp extension aimed at simplifying the process of face creation from edges and offering efficient face extrusion capabilities.
FaceUp has three tools:
Three ways to access FaceUp:
-Toolbar: Go to View > Toolbars > FaceUp.
-Context menu: Right-click on selected faces/edges and go to FaceUp context menu.
-Extensions menu: Go to Extensions > FaceUp.

...this is so good! I love it, it´s richness of detail and it´s sketchy style
Hi HornOxx! Thank you so much, so kind!
Glad you liked it
Hi there folks!
I want to share a personal project I’ve made during these last two weeks. I want to share a personal project I’ve made during the last two weeks. I always loved this kind of drawning, but I never give it a try (until now!). I’m really happy with the results and I’m sure I’m going to try again in the future. Hope you like it!

Hi there! There's been a while since my last post
Here's a sci-fi corridor I made during a live streaming.
Modeled with SketchUp 2021, it was about three hours of work
The stream can be watched here (spanish language).
Hello there!
Here's a vintage fan I modelled yesterday. Besides SUbD I used some other extensions like VertexTools and QuadFace Tools.
Hi everyone! Here's a recent exercise I made with SketchUp 2019, SUbD, VertexTools and QuadFace Tools. It's the head of a corinthian column. I used Thea for SketchUp v2 for the rendered pic.
What about the possibility of setting a minimum margin between islands.
Sometimes the resultant ones are too close one to another. If that happens, I usually have to face some color contamination when I'm painting the model
