4D Virtual Builder

I have recently downloaded the free trial of 4D Virtual Builder (I use Sketchup Pro 2017). It downloaded all fine - but when I try to import an Asta PowerProject file, I get the alert “Unable to read the file”. It doesn’t give any reasons why it can’t read the file or any options to choose to rectify the issue.

Can anyone help please?

I contacted Sketchup but have had no reply.

You should contact the 4D Virtual Builder people, not the SketchUp team.


Hi Dave
I have already contacted them and have had no response. I have just sent another message to them.

Hopefully they will help you out.Since it is their extension that you are having trouble with, they should sort you out.Or maybe you need to contact the Asta PowerProject people. Maybe it has something to do with the file you are getting from that.

That’s a good idea, I didn’t think of contacting Asta, I’ll give that a go.

I realize this is an old thread, but does anyone know if 4D Virtual Builder is still supported? I have not had a response back but interested in the plugin. Last update to website was 2014
