Imported DWG into sketch disappearing when scale is 1:1? Help??

[ptc-5007091]

I'm having an issue with my imported DWG file disappearing. Whenever I import it at 1:1 scale, the sketch disappears. It will only stay if I keep the scale at a higher number, The sketch is a simple cylinder profile which i'm goign to revolve. Is it having problems with adding dimensions and thats why it's disappearing? The steps I take are begin a new sketch on a plane and choose Get Data>File System. Choose profile DWG and change import scale to 1:1. When I hit the green check mark, the sketch disappears. Help??

I just tried it by importing a drawing from McMaster-Carr. It failed and provided the message that the solver failed.

These were the 4 lines in the history lines:

Degenerate entity of type "Line" encountered in the import list has been removed.

Underdimensioned section. Please align to part or add dimensions.

Section solve failed.

Confirm request to quit.

You might need to clean up the DWG by creating it as a part or drawing and then creating a sketch from that.
