Hi Sheri!
I also use CorelDRAW to draft shop drawings for a full fabrication sign company.
While I find Sketchup Pro to be a very valuable tool for my more complicated projects, I haven’t dived into LayOut as much. Mostly I use Sketchup for pylon structures as I have found it time consuming to draw all parts of a set of channel letters for a full Sketchup model… If there are any extensions out there to make trimcaps and return flanges easier, I’d love to find them!

Often I will start with CorelDRAW to generate scaled vector graphics to base my 3D models from in Sketchup Pro. For some reason CorelDRAW isn’t great at exporting DXF files that import nicely into Sketchup so I use the free software Inkscape as a go-between. Once I have a 3D model that I’m happy with, then I’ll export various “views” in vector PDF format for my shop drawings in CorelDRAW.
Here’s a few drawings I’ve done recently using this process…
BDO Letters on Rails - ISO.pdf (194.7 KB)
Crichigno Orthodontics - Pylon Sign.pdf (1.3 MB)
Stoney Creek BIA - Pylon Sign.pdf (697.1 KB)
I’m sure if I invested the time to learn LayOut that would make cut lists and bills of materials much easier to generate. I know there are import / export options for Excel spreadsheets for this purpose but so far I haven’t explored all the possibilities.
