Making object watertight/solid

[Anonymous]

I've been pulling my hair out trying to make this work.  I've tried the surfsculpt, thicken, slice, separate, convert to solid, union.  I've created a region beneath the object and can't seem to find any solution.  The outside ring is fine, just what's inside the ring I've spent hours trying to work out.

How can I get this object solid??  Can someone please let me know or give me a hand and send me a solution?

Hi,

also the inner object can be converted to a 3D-Solid using command _SURFSCULPT.

I selected the surface + the region, started the command and that did it.

I know I've tried doing this, but it must be the order that got it right!  Thank you so much!

Hi i have trying to work with the real street canyon model for studying pressure coefficient in the buildings facades. for this purpose i used placemakers revit to export real model of a small area in Olso. After exporting i checked the real height of the buildings from google earth pro and open street map data and found that some buildings were having discrepencies in the height. I corrected them in the Revit with extrusion option. Now it seems there is a water tight problem and polyfaces mesh needs to be converted to solid along with the terrain. Can anyone suggest me some possible way to deal with it. Finally i want to export this attached autocad file to iges format and carryout CFD simulation in Simcentre star ccm+.

Thank you

the file attached here is an autocad model and the path flow of the model is

Hi,

these objects can't be converted to solids with any out-of-the-box function. Also the meshes are overlapping and intersecting, so also tools that might work with polymeshes conversion to 3D-Solids will fail.

The question I have first: where did you get the data from, I guess there exists some GIS-data with building outlines + information about the height of the object. If you have such data it might be more easy to create 3D-Solids from this than to edit this dwg models.
