Tools on surface not working

Rich O Brien

SketchUp has limitations healing edges when they are below 1mm. Are you encountering that limit?

If yes, scale the object 10 - 100x and try drawing.

Krass

yes you are right! I forgot to scale the object... But at the end, I did it manualy

Krass

I enlarged it by a factor of 100, but it doesn't work.

Krass

Actually, it works better; I tested it elsewhere and the rectangle isolated the face well.

Rich O Brien

In 90% of edges not healing or holes not filling or missing it is edge size.

If you are importing scans it is best to x100 the scale to avoid this behaviour.

Dave R

I often work with a scale of 1000x. I can treat millmeters as meters that way.

Mike Amos

The simplest way to deal with many errors, imho.

Krass

Thank you: multiplied by a thousand, it's perfect!
