Thanks guys,
Just to reiterate, the goal here is to get a very quick workflow to 3D print Revit elements.
My conclusion is that the graph above gives a successful outcome.
As a different kind of test, I made a deliberately very messy model to see what would happen…
Revit
Meshmixer
Cura
This was with no work done in Meshmixer apart from ‘Combining’.
Total time from Revit to Cura less than 5 minutes. For me, this means a quick concept model can be printed and taken to meetings as part of the design development workflow.
Later on a more perfect model could be made for larger scale prints / presentations.
I didn’t have much success working inside Meshmixer, none of the ‘Make Solid’ settings gave outcomes that I was happy with, I would do any repair work within Revit (when the export is that fast, it seems more efficient).
Some other points:
I think families will need to be built specifically to be 3D print compatable.
Getting rid of model lines and making sure family elements stopped me getting wierd messages.
Adding a recessed extrusion which completely fills the family opening (but is invisible apart from 3D views )
reduces the evil red spheres.
I have also knocked up a graph which takes a CAD import and exports it from Revit to Dynamo to Meshmixer DwgImportFromRevitToMeshmixer.dyn (16.1 KB). This isn’t perfect, but is much more efficient than Sketchup > Solid Inspector.
Cheers,
Mark
