Okay, I found a solution, I should have had the if statement in the plugin I wanted to run.

This isn't a method, but an outline of a process... You have a component-instance. From that instance you can get the component-definition. You can then add a new instance of that into the same entities-context as the original instance, using a copy of the original's transformation. Now you can process that new instance. For example, you can explode it get a reference to everything, then erase everything that's not an edge - e.g. faces, text, dims, and nested groups and instances. Now you have the edges. If you'd like a group containing just those edges... Once you have the component-definition, you first add a new empty group into the same entities-context. You can now make a reference to the group.entities context and then add the new instance into that new context, explode and trim the array of entities, to finally leave only the desired edges inside the group. Now you have the required edges inside your group. [Remember that you can rename that container group etc as desired]

You have the center, radius and normal before you add the circle. Then when you add the circle it returns an array of edges edges = entities.add_circle(...) From any one of those edges you can get the ArcCurve, and from that you can get its center, radius and normal. I still think this can be done more simply. But if you have something that works... then go with it...

Is there a way to pre-configure "Check Fredo6 Plugins for Update" to "Never show this dialog again"? Basically, I never want this feature to pop up for users and check for updates. If I choose "Never show..." in that pop up where does that get stored? We run a managed environment across all our computers. We deploy SketchUp plugins to C:\ProgramData\SketchUp\SketchUp 2018\SketchUp\Plugins\ so that all the plugins are available to any user of a given computer. When a plugin has been updated by a developer we deploy it to all computers to keep everyone on the same version. I would like to preset the parameter to never check for Fredo6 plugin updates. Thanks!

@Dan: Layer feature done See here: https://sketchucation.com/forums/viewtopic.php?f=323&t=70361

I found it, it was a test .rb file, not a plugin but it did have def get_from_excel That is where the plugin was getting the code from. Thank you, The style does change now that I am in the correct code.

I guess you have to download the file to local disk,then apply it in your model, of course, you can use ruby to do it automaticly

@juju said: I know of RoomSketcher, but I don't think it imports SKP files. Actually looks pretty good. May be useful for some clients

Also remember that your code as we can see it ALWAYS does a commit - even if there was never an operation started. But since we only see some of your code it's unclear if there's always an operation to be committed ! One way round that is initially to set **@**draw_status = false, then within the 'tests' use **@**draw_status = @model1.start_operation(@Model_operation, true) e.g. in if @Trusstype... Always remembering to set in each 'test': and then in your unshown code, for each commit you need to use: draw_status = @model1.commit_operation if **@**draw_status So you don't commit anything unless an operation is been started...

Why would you want to use Python instead of Ruby? You can try using Python to talk to Javascript and then javascript talk to SketchUp is Ruby API. There is also a C API but I have never used it. Good luck!

Yeehaaa here's a dummy way with a tetrahedron fudge your model with a face on x,y plane and one edge on the x axis - you hope. this face must be filled draw a flat rectangle joining this edge at both end and extend along the flat plane y. It should fill by itself. the line in between can be removed and it should all fill - if not you screwed up placing your model I think this is fundamental to any modelling (would you start a 2d drg without an origin, scale and xy directions [image: coplanarity.jpg]

Your current 'circle' code only draws some edges [all be it that they are in the form of circles]. Use e.g. edges=ents.add_circle(@pt1, @vec3, @dia, 24) Then make a face for one of those edges... ents.find_faces(edges[0]) face=edges[0].faces[0] Then add a material to the 'face'... Of course this is very simplistic... e.g. if your circles might overlap etc not all edges might get a face, so then you probably need to make each circle/face inside its own group in turn, at least until you have finished making/painting it etc, after which exploding the temp-group can put the faces back into the desired entities-context...

Hi thanx for the heads up, I thoought I was probably being simplistic Its a pity that SUC does allow more realistic FB to developers. Some of the stuff is brill and I would give 5* But I am strictly on the geometric solids/eng side and SU is mainly for graphics and visualisers I guess

ENV["LD_LIBRARY_PATH"] is for standalone Ruby. I'm surprised if it works at all in embedded Ruby. Same for Open3. I've heard of nothing but problems with it under SketchUp embedded Ruby. Suggest you try to wrap Emp using the Ruby Fiddle library ... http://ruby-doc.org/stdlib-2.2.4/libdoc/fiddle/rdoc/Fiddle/Importer.html P.S. - Your code is hard to read on GitHub because your indents are being replaced with 8 spaced TABs. Ruby looks best with 2 space indents. Most code editors can replace TAB with space characters as you type, and you will not get these giants indents when you post code.

Thanks again for the reply TIG. Unfortunately, I see the same issues. To verify it wasn't the small differences in faces from DropVertices, I made a copy of the bottom textured model and moved it directly above. I removed the top materials and then ran the script. UV issue is still there. Have you actually downloaded the file and run this script with the top mesh faces selected? Have you seen the UV issues or did it look okay for you? Honestly, I guess I will just give up at this point. I have figured out another sort of workaround where I make a sandbox mesh above the original, run this script we wrote (which does perfectly with the texture and UVs when the raycast is from a flat surface), then use UVToolkit to save the UVs, then drop the vertices and then restore the UVs. It works. A few extra steps but this script has been enough of a headache. Regardless, thanks for your help.

Thanks for all that info fredo... It'll certainly come in handy

GUI like TopoShaper and my other plugins' are drawn in the viewport and constantly refreshed (at each view.invalidate). So this is a very different technique compared with HTML dialogs. Benefits: you can use a state driven approach, since the refresh is permanent you do not have problems of focus between the Sketchup window and the dialog box Drawbacks you have to draw everything with the OpenGL methods (i.e. view.draw2d()), and manage the interactivity with onLButtonDown, onLButtonDown and onMouseMove()). The GUI takes some real-estate on the Sketchup viewport. And also, it disappears when you Orbit or pan Some users don't like it, as it is 'non standard' (by the way, when looking at Web Sites, this difficult to say that there are standard in HTML too!) Note that HTML / JavaScript / CSS, you can make the programming state driven by using frameworks like Vue and Bootstrap. There is a learning curve but overall it's working fine. For the focus, this is more complex to handle, but there is a technique to force Sketchup to give back focus to itself. Fredo

I had a similar problem where I are getting this message every time I tried to save: "*** Problems were found that could not be fixed! *** The name for CMaterial (290526) is not valid". It would still let me save the file though. I was able to solve the problem by opening the materials window and hovering over each material to look at the name. I found 3 materials that somehow had blank names. After renaming those materials the problem went away. I don't know how those blank named materials got there in the first place though, I tried to recreate the problem but SketchUp won't let you name a material with a blank name.

It worked wonderfully! I was using the load_from_url method with a file:// prefix before, and it also worked... but this makes more sense. Thanks!

dude, did you know that everytime you save a scene there is the option to save it with the current settings? Maybe this wasn't the case back in 2013 but there you go
