Old AutoCad Floorplan - Walls Drawn as Hollow Poly-Lines

Rhino Rhino for Windows
1

I have an Autocad LT floorpan drawing that I created in 1995. Yep 1995. The walls were drawn as 3.5" hollow walls with closed hairline polylines, not 3.5" wide polylines.

I’m getting ready to create the 3D model of the home.

I am able to open a version with Rhino that was saved as Autocad v13 , and extrude the curves as solild walls, but before I proceed using that method, I’d like to convert the hollow wall curves to solid.

Any tips on how I can clean this up before I start the 3D model?

Thanks

When you are importing DWG files, there’s an option saying “import polyline with widths as surface”.

Thansk, I tried this, but no success.

If they are joined polylines - i.e. closed and planar - when they come in, you should be able to be able to select them all and run PlanarSrf to put surfaces in there. You could also use Hatch (solid) if all you want is something visual in 2D.

Thanks, PlanarSrf command worked to achieve the desired result.
