Anyone using 2-1/2 D?

I was wondering, does anyone still use 2-1/2 D drawing? When I go to draw something for 3D use I prefer to either draw it using the actual 3D entities in Datacad (polylines, polygons or slabs), or if I am going to push/pull in another app I like to draw it in Datacad 2D linework and then use the native 3D entities of the other app to build my objects from the 2D linework. I was just curious if anyone is using z-base/heights for their 2D entities with the intention of using them for 3D anymore?

We don't use the 2 1/2 D features because the geometry doesn't translate over to Sketchup, etc.
We are also finding that our engineers have trouble with our files if everything isn't flattened out to Zero Z-base and Z-height.
David Henderson has written a nifty little macro that will automatically zero out everything in a drawing file that comes in handy. I suspect that he will respond with a download link.

Occasionally, I use Z values to exclude / include entities in a Clip Cube - for 2D construction drawing purposes.

Would respond with a link if I was aware of it ....
Perhaps Jim is thinking of a macro by somebody else ? If so I assume that some-one will chime in with the details. ... Or perhaps I've just forgotten that I wrote it? (not impossible, but if so perhaps someone can send me a copy?)
I expect that it would only take an hour or so to write such a macro, so I might look at it if nobody points out an existing macro.

David: I could have sworn that you sent it to me.
I attached the macro. It has no interface and will reset the z heights on all layers to zero. This will not change the heights of entities that are already in the drawings however.

But the drawing
Repair function can!

Since we can flatten entities when exporting a file, why can we not have that switch on when importing a file?

I have made it a habit that once I import any file that is not native Datacad AEC, once the file has been imported into a new default file, to close the file and run the repair tool on it to help purge any funkyness out of it. I usually always set it to use the Z settings Dave shows above. It's just too easy to do and hopefully helps me avoid some glitches down the road.

Excellent advise (as always)

ok, it may have been me ... I do have the source code for the Z macro on my PC,
so I guess it must have been me.
It was probably just something I wrote for you in a few minutes and I never made publicly available (and subsequently forgot about). Maybe I should add it to my web site, but I guess anybody who would find it useful can download it from your post ...
Rgds,
David

That does sound about right. I think we were discussing the space planner macro and I mentioned needing to change the z information on layers in our drawings.

In 25, 30? years of using Datacad, I can't think of when I've used it deliberately in 3D-mode. I use Sketchup for that, it's just so much more intuitive. That and I don't use Datacad intensively-enough to learn half it's functions. I just don't have a drafting-intensive practice at the moment.
I primarily use Datacad for 2D construction details, floor-plans and building sections, and site plans. Everything else is primarily-done with Sketchup-Pro and Layout.

I use a DWG export/import of accurate DataCAD drawing to Sketchup to model my 3D work with the exception being topo contours.
I did get my start in architectural 3D with DataCAD but now find I can almost model as fast in Sketchup as I can draw in 2D in DataCAD.
I've said this before but we really don't need or want a tool to do everything as parts will always suffer when going this route. I have several saws and hammers in my workshop...pick the right tool for the job and your expertise level
