Cilinder effect 2d (error in 2018)

This routine give a nice touch to round stuff in 2D.

Problem is i can't get it to work in 2018, it quits after findfile "acad.exe"

Any idea what this could be?

Also: i need to get it to work in a rotated UCS, not WCS.

Regarding issue #1:

Windows restricts access to certain critical folders and you probably do not have permission to write to the folder where acad.exe is located. Try changing "acad.exe" to "acad.pat".

Thanks Roy, that did the trick indeed.

The angle of the created hatch (& units set in grad) results in funny cilinders

But that's all cosmetics ;-) glad you made it work again!

Recieved this link which describes it perfectly.https://screencast-o-matic.com/watch/cFeobrDZOy
