This question was addressed here a few years ago, but at the time there was no simple solution offered.
I have a project that we did some years ago, with a 3D model prepared on Form Z. I never used that program—the model was done by a former employee—not do I have the program any longer. We have now been asked to additional work on the project and I would like to know if anyone has an idea for how to import the Form Z model into Sketchup.
You can always download and install Form Z Free, you are allowed to use it for ANY purpose. Open the model and save as a .dae file and see how that works. Or download and install the Form Z 30 day demo and export out to other file formats and see what works.
I downloaded Form Z-Free, very easy, and installed it. Have not looked at it in 20 years or so, I’d guess, and even then I was not the one actually using it. The UI seems very similar to Sketchup, as it was easy to make my way around.
I exported my file as a .dae file, just as Sean had suggested. Then I imported that file into Sketchup and it appeared in quite good shape, just lines, no materials or whatever, but that was all I wanted anyway. The second file stumbled on the export and I had to ungroup the model for some reason, and then it came into Sketchup without any issue.
I just wanted the line work, as I am using it as a sort of existing conditions model, so the process worked well for what I needed.
