I've actually got a Company logo that I would like to convert from the image I am currently using to Revit Objects. The logo was created in AutoCAD, and there are some areas of the text that are 3/256" tall, and you can tell if it's not right...it has to do with the text size.

Another interesting thing...all of it was almost like exploded text...it was a consistent looking font, but it was all linework. So to get the custom look, I would have to repeat this in Revit, but some of the lines are too small.

The trick is to do it at a bigger scale in a family (works in Generic Annotation family for this application or you can also use Detail Component families for fine amounts of detail), and then scale down.. I just brought in the CAD file, scaled it up x10, and xploded it. Converted all the linework but a few lines, which I will correct and scale back down, and bring into my TB as an nested family.

This works in theory as well in the Generic Annotation family, assuming the lines aren't ridiculously small to begin with in AutoCAD...some of the lines used to draw the dots above the 'i"s are 0.00269294" long. That's really, really small, and with that said, this method still doesn't work, because when I reduce it back down after scaling it up, these lines are smaller that whatever the smallest line Revit will actually allow...which I think is 1/256"??

Anyhow, looks like I'm still gonna be converting all these segemented polylines to splines and hope that they scale!
