SketchUp's default extension installation path is... C;\Users\SomeName\AppData\Roaming\SketchUp\SketchUp 2022\SketchUp\Plugins Our ExtensionStore detects when there is additional extension locations as some third party apps, like render engines, will install extensions in other locations... [image: WA2FT1p.png] Always pick the top path to ensure correct installation unless you know for sure any additional path are needed. You screenshot of your Extension Manager dialog is showing that RoundCorner, Visuhole etc are not installed in the expected location.

@rshawiii said: Is is possible to combine multiple fredo-splines. I want to join them at their endpoints, then have the two original splines behave as a single spline that can be edited/adjusted going forward. Combining 2 splines into one would cause each spline to be (slightly) modified to ensure continuity at the junction. This is not supported currently by FredoSpline, but can probably be done (although not trivial in the general case). Same, by the way, for the split of splines, that is, cut a spline into pieces which are also splines. Currently, the only thing you can do is to extend a spline by its extremity.

Normally you don't have any problem with Hull's ship with the Fredo Curviloft! All must be drawn in one pass I believe you have false drawn your curves but with what reason ...no ideas Bon courage and wait the Fredo advices! But for me any spline(s) drawn in order in Layer 0 must draw any ship! (see the Fredo avatar By Axeonalias [image: 5538065865_60e0d74feb_b.jpg] https://www.youtube.com/watch?v=1y8MR6_kUoU

@rshawiii said: more visual indication of the status would still be nice. Thanks for the quick response. When you are in no-inferencing mode, the vertex you move is circled in pink.

Seems to be working now. Not my imagination it was not before. Bizarre. I did not try to recreate the workflow I was doing exactly. It involves a large mesh (1M triangles) and creating splines at intersecting faces. sketchup and computer seems stressed with this. When I get back on it for real, If I have a problem, will let you know. Thanks for the fast response.
