I was asked to create some quick elevations of a large project for council discussions and I thought this was a chance to try out Impression2 from Adesk. So I downloaded and tried it out. It is quite easy and links (updates) really well (especially after using the VizRender link). If you are still on subscription it's a free download so defintely well worth a try. It may only be available with a sub so if you are not on sub you may be out of luck.
It ignored my linework (didn't show) and I had to use rectangles or closed PLines so I had something to 'fill'. But the height lines showed so I don't understand what happened there. Still some learning to do but what you see took me about 20mins for a first try.
Now I'm sure you have a project more exciting than mine to work on so go for it. Give it a try.
