Dear all,

I'm new to Strata and have done I few tutorials and I love it. Very easy to use but I run into a problem. When I import a dxf file from autocad I can not see it. I can zoom out all the way and still not be able to see it. In autocad I can save a file as dxf under different versions to be able to import in other programs and I tried all.
What am I doing wrong? can some one help me. I have a few projects that I would like to render?

Do you see an entry in the Project Window for these items?

When you open the files, select Command+=(equal/plus sign). This will zoom the scene to the extend of your objects which should help you to see what's there.

You need to be sure your DXF is saved in version 12 or earlier.

To begin with, I just converted my file to a 3ds file which I have not tried yet to import and second I'm a PC user so what is the replacement to command (-+). Is it CTRL?

Yes, the Command key on the Mac is the same as the Control key on a Windows system.

I did save it as dxf release 12 and it worked but it transformed my 3d solid shape in something else. What's going on?

Impossible to say without seeing the file.

The forums are going to be taken offline in a little while. You should contact me directly at support (at) strata (dot) com.

Brian,
I work with 3d solids in autocad 2007. There is anything else that i have to do wiht the solids before i save the file as RTL12? Should I explode them to turned them into regions? Or explode one more time to turn them into polylines?
Thank you

Strata cannot import 3d solids.

Can you convert them to polygon meshes?

Jean, Brian and Chris,

Finally, I did it. I downloaded a trial version for a convertor from solid to polymesh. I converted the solid to polymesh then saved the file as RT12 dxf, imported the file to strata and it works. I just have to disolve a lot of meshes to apply some texture.
Does any one know about a free convertor solid to mesh?

I really appreciate your very quick response and support,

Cheers

I use FBX Converter for this kind of thing a lot. There are other inexpensive CAD programs such as ViaCAD which also do a good job.

Yes, ViaCAD would fit very nicely into your workflow if the ~100 dollars is in your budget.

ViaCAD is built on the same ACIS engine that AutoCAD is built on, so it should import you models well. It will also tesselate your solids to a nicer format than DXF: like VRML2 or OBJ.

try before you buy, and see if it does what you need. The have a nice trial period.

You can send me your file and I'll take a look at it. I do this every day, but use Vectorworks to organize the file then export as Simple Vectorscript. This will retain any layer information and import as named shapes. It will retain scaling information.

This can be problematic, depending on how they set-up the file.
