Axonometry from Mesh

Hi everyone,

I would like to make an axonometric model of a part of Copenhagen. I have attached a reference image of what I am aiming for. There are several open data .dwg files, which I would like to use for the model. However, these are all mesh geometries and extremely heavy files. I am unfortunately very inexperienced when it comes to mesh geometries. When I '_Make2D of the mesh geometry, all the meshes are visible in the line drawing.

Is there a way to simplify the geometry (possibly make a polysurface) so that it becomes easier to make an axonometric view of the geometry?

Normally Rhino 6 and 7 handles such case quite well.
When you use Make2D command deselect hidden lines.

If you really want to have Breps, then MeshToNURB->MergeAllCopanarFaces

In all cases it is going to be a heavy operation for so many solids.

Thanks for the quick reply!

I have been trying a lot around with '_MeshToNurb and '_MergeAllFaces, but unfortunately the faces cannot be simplified further, making it difficult to make a '_Silhoutte.

Do you have any tips on how to get the 3D geometry only to show the edges/borders?

You don’t need to convert to surfaces just to not show hidden lines of a mesh.
Make sure this option is unchecked when running the Make2D command:

Thank for your reply!

It makes a lot sense that the meshes would disappear when having hidden lines unchecked, however, when I try doing that, the mesh lines are always visible unfortunately.

Do you have lots of unwelded edges in your mesh?
Try running the Weld command first to avoid showing creases on the flat faces.

That helps! Thanks a lot!
