Hi All, I would like to 3D print my Revit, this blog describes a process where you build a mass within your Revit file which is exported. [image] 3D Printing and Revit - Yes, It's Possible, and Here's How ... When I was given the opportunity to purchase and use a LulzBot Taz 6 my first…

@Mark.Ackerley You could try to … Create a solid bounding box Subtract the building mass from the bounding box Remove the outside component of the resulting solid Something like this … [3DPrint] 3DPrint.dyn (17.0 KB) 3DPrint.rvt (1.5 MB)

@Mark.Ackerley Are you saying the model would be printed solid i.e not hollow? Other applications have tools to create a ‘shrink-wrap’ mesh over a model, and then you can thicken that mesh inwards.The mesh needs to be manifold i.e can exist in the real world. It depends on the type of 3D printer &…

Thanks Andrew, My goal with this process is to optimise the workflow between Revit and the Print, if there is a need for some tweaking in Rhino I’d be happy with that (the blog required manual replication of the Revit file as masses), mind you Vikram’s output is manifold! I get what you’re saying …

[image] Mark.Ackerley: I’ve attached a Revit file if you wouldn’t mind a look? Don’t see any attachment Meanwhile check if replacing windows and doors with alternate families helps

Wetransfer link… https://we.tl/U1rfLrpznC Swapping out avoids the error messages, so they are linked to the families… I’ve found another error message… “Warning: Solid.ByUnion operation failed. Unable union two Solids : INCONS_VERT_ATT – inconsistent information in vertex and coedge attributes” …

Do the following … Detatch all walls, alter the profile instead Create a floor [3DPrint2]

Interested to see how it works out, but out some point, you’ll need to create a mesh (STL file) from the model & it is unlikely that this mesh will be 100% printer ready. Applications such as Meshmixer (free), Netfabb (a few hundred dollars) or CADSpan (a few hundred dollars) have the tools to do w…

Not sure if it’s printable, but here is the STL file of the above model exported from Dynamo model.stl (660.5 KB)

It’s not bad- Meshmixer says that there are some non-manifold surfaces (red) and very small objects (purple) These small objects look like the gutter profile which has not been exported properly. Without spending too much time tweaking settings- the third screenshot shows results from Meshmixer ‘m…

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 [3D] Meshmixer [3D1…
