Hi, I’m trying to use my trilateration plugin (Didier Burr) I get the option to select my preferences but each time I indicate the first triangle side and before I can input the other 2 lengths I get the spinning ball and application not responding. I’ve tried it about 10 times now! I’m assuming it’s not compatible with SU 20. Any suggestions? 
Kind regards, Sally
Did you restart SketchUp after installing the plugin? It works ok in SU2020
Hi Mihai, yes I did. I’ve reloaded it and re-started. It’s exactly the same each time I try it, as soon as I set the first line, it hangs and I have to force quit…
I can’t speak for Didier’s extension, but as an alternative you could try mine, which does both 2D and 3D.. I am running Big Sur, not 10.14, but I don’t think that should be an issue as I was on either 10.14 or 10.15 when I wrote it . Also I know it still works through SU 2021.
Thanks Steve, I’ll take a look tomorrow. I’ll get back to you 
Hi again Steve, thanks, yours loaded and worked just fine.
