Blender Import ?

[Ethan R. 35]

Hi all,

I have a buildilng model that was made in Blender and I'm trying to import into VectorWorks.

Is there a workflow that works?

Any outside software needed as a magic box?

ie. Blender -> 3DStudio -> VectorWorks

 

thank you

Can you export an *.obj from blender?

[Ethan R. 35]

Yes - that is the file you have in the slack 🙂

It comes in as Meshes however; which is a drag.

 

Blender -> OBJ  <-- VectorWorks

an .fbx file import would be much better.

does c4d take .FBX ?

Of course.

 

 

VW to Blender (Modo, C4D, ....) by FBX works great.

Bringing in data from 3D Apps to VW (or any CAD) not so much ....

 

And you would rarely get any Solids from Meshes.

I don't know any automated workflow.

Normally you would have to explode each Mesh and Stitch it manually.

That is what I do all day, for CAD to CAD exchange alone.

Either for things that get lost in translation or things that never have been

Solids, like Revit or VW PIOs.

 

Somehow IFC seems to bring in Solids into Bricscad, from Objects that

haven't been Solids before, while IFC to Modo brings often Meshes from

things that were Solids !?

So maybe it's worth trying to get IFC in between your import journey.

@zoomer Does that mean you can go Blender - FBX -> C4D -> VectorWorks ?

[zoomer 767]

Unfortunately no,

I don't know any lossless solution to bring C4D into VW

(I think C4D Exchange in Allplan or Archicad works in 2-ways)

 

Maybe C4D via DXF will bring 3D Meshes into VW ?

C4D has OBJ Export and VW has OBJ import.

Maybe you get a Sketchup file out under way,

which VW can also import ?

[Ethan R. 35]

ugh - what a pain in the ass 🙂

 

Thanks!

I see Blender can directly Export OBJ and DXF (AddOn)

[Ethan R. 35]

OBJ comes in as mesh.

Will try the .3ds and .dxf next 🙂

 

[zoomer 767]

I'm pretty sure it will always come in a s Mesh only.

 

It is more about bringing Object Hierarchies, Names, Materials, ... in.

If you have objects nicely separated, you can convert them one by one

to NURBS Surfaces and Stitch and Trim them from advanced 3D Power Pack

from menu.

You can even Stitch many Objects at a time - as long as they don't touch each other.

I think Stitch in VW works pretty forgiving with bad geometry.

 

 

In many cases, snapping to and recreating geometry in VW may be the more reliable

and even faster way.

 

BTW the wisch for an FBX import was often asked.

Thinking of giving this a try .

Ethan - I believe (and please - someone from VW tell me if I'm wrong) you are trying to go a from polygonal based modeled objects (Blender, C4D, Maya, basically all 3D DCC Apps) into a CAD program that uses Nurbs/polylines (and math) to create objects between points.  So I don't think you are ever going to get anything but meshes coming into a CAD program.  The reverse is easier since faceting those nurbs into polygons is an obtainable (destructive) workflow.  It's not perfect (hence the triangles we deal with), but it works.  The reverse - not so much.

@EAlexander Now that is an explanation that makes sense.  Modeling vs. CAD

Thank you

In theory, you can convert a mesh model into a NURBS model using VectorScript. I use this method when exporting models from TouchCAD, where I do 90% of my free form shaping. The procedure allows me to export either as a mesh or as NURBS surfaces, which can be used directly as solids. I need both methods as VW's NURBS abilities sometimes get a bit overwhelmed by the TouchCAD data. I'm however not sure how well a general purpose import features would work, as there are many possible variations in the setup of the data, whereas in TouchCAD's output is very predictable and therefore works very well.

 

There are some other programs having such conversion features. ViaCAD Pro used to have an extension called PowerPack, which did a decent job, but apparently they have removed it due to some legal issues. 

[zoomer 767]

And BTW,

clean and watertight Meshes can be converted directly into Generic Solids in VW.

 

I just make tests with PushPull Tool if it got really a Solid. If PPT doesn't work,

something went wrong 🙂
