About a 1/2 hour ago I opened a ticket on “Stuck on Rendering Design”. You May now close it.
I searched and read all I could find on “Stuck on Rendering Design”
None of it worked for me.
I could open and use other files on my computer but not this particular one.
I am using Inkscape for my SVG Output.
I tried copying out the file to a new file.
Tried copying out Parts to a new file.
None of it worked.
I sat and thought about it some and it occurred to me there was one thing I hadn’t tried.
I saved it as a PDF.
It opened the PDF with no Problem.
This may not work for everyone, but it worked for me, and I thought I would share.
