I am unable to draw a surface based on curves located in the attached reference of an SLT file. At first, i thought it was because the reference file was open. I closed it. Still could not select a curve. Closed the holding/parent file and then restarted Shark. Still, no difference.

I can, however, draw new curves from attached external references.

It should be possible to draw a surface. But, I cannot select the curves (fence or click or otherwise) when cursor mode is the surface tool.

I can select groups of curves but not individual curves.

I want to be able to click individual curves of an an attached reference drawing.

Can you make it possible to click on entities of an external reference and obtain geometry info?

Also, can you make it possible to in-session or persistently alter colors of geometry in an external reference? It sometimes is necessary to help mitigate the effects of view clutter.

Can you also make it possible to hide/unhide individual entities of an xref? (I think I tried and failed.)
