continuous surface creation from multiple regions

[stefano bertocchi]

Hello, everyone.

I am facing the design of an underground garage. to do this I have to create a fem model starting from an autocad base. I have created the basis of my mesh with so many regions as the walls and the roofing loft, thus obtaining a surface in the space formed by the set of individual regions, and then importing them into my computing software (straus7) as acis.sat file. In this way, the meshatore of the program treats the individual regions one by one and I sometimes have conflict between the knots of the structure. My question is: does there exist in autocad a command that allows me to transform the individual regions into a single surface? Or do you exist/know a software that can do this? I hope I explained.

thanks for the collaboration

if the regions are clear the joint command should do what you are looking for

convinsuperf + union

x tristan: thank you for the resonances ok. I explained badly myself. You have to imagine that I have a box with internal walls composed of regions in space so I also have regions among them orthogonal. tomorrow if I can place an image of my model

xgp: thank you for the answer first. in which menu do I find the command or just edit it from the keyboard? I use the 2008 autocad version. in it is already implemented this command? Thank you!

the commands can be typed, convinsuperf exists from autocad 2007 and allows to transform even the regions, the problem is that with 2008 union only works on solids and comlanar regions.

If it were the same you could turn all regions into solids by extruding with an infinitesimal thickness (e.g. 0.00001) and then union to create a unique solid.

Thank you. but on a more recent version of autocad type 2012 oppurue revit there is the possibility to use "union" also on non-complanar regions? or I thought maybe rhinoceros might do this. Do you know anything?

Thanks again

 

[GP.]

also with 2012 the regions must be combined, but union also works on the surfaces (with 2008 no).
then if you turn regions into surfaces (convinsuperf) you can then use union to create a unique one.
I don't know.

Perfect! So if I understood well once I have all the regions of my "box" turned into independent surfaces, I can then join them to form a single surface. Thank you very much!
