CNC pattern
-
The next installment of this project is CNC cutting and SU Solid worked fine until you get to Injection Moulding or Rapid prototyping stage....
The companies want IGES constructed on Solidworks, I've tried STL files and the IGES plug in and it exports a mesh mess
Anybody doing this kind of work got any other ideas, Sketch up into Solidworks ??
-
You can export a dxf or stl from Sketchup and import that into Solidworks, but that doesn't usually cut it for injection molding. You either have to rebuild it in Solidworks, or try Spaceclaim to convert to IGES or STEP.
Here's mode about using Sketchup and Spaceclaim: a Youtube video

Sketchupdate blog post.Thanks, that was my conclusion too - Spaceclaim is only Windows though.
Is there any tips for making the transfer from sketch up to Solidworks easier, I have to translate my idea's to the product designer and an awful lot of time has already gone into it for it to be a redraw -
Hi there
I find the best route would be via Rhino. Here is the link which explains how to take it from rhino to solidworks. You have ability in Rhino to to resurface it and use nurbs. To bring it to rhino I would sugest either .obj or .dwg.

-
Yeah solidworks is windows as well. Rhino uses the same manifold 3D as solidworks ? And, will it be OK for injection moulding, I know it does nurbs as I have used it in Uni
-
Maybe this can interest you (for PC)
Sketchup to Rhino or any Nurbs programs : format OBJ to format 3Dm
It's a free Prog "Obj23dmWireframe" made by Michael Gibson the creator of Moi
(unzipp it)Just export your model from SU in OBJ format by the TIG OBJ_Exporter (if you have just free version of SU)
Then launch the "Obj23dmWireframe" prog!
You have 2 choices- each segments will became a simple line (without double)
or more interesting! - each planes faces will become a closed polylines! So can be easily a face in a Nurbs prog!
And of course can be filleted etc...
Can of course works with any "obj file"!
But don't take obj files like OBJ Zbrush file (millions of polygons)
- each segments will became a simple line (without double)

Rhino is good for injection moulding, rapid prototyping etc. You will have to make sure that nurbs surfaces do not have naked edges...means you have to produce clean geometry.
Btw Rhino has been used a lot in industry to convert 3rd party files to solidworks geometry.
As Pilou says MOI is as well good option for .3DM. -
Thanks guys, I have Rhino up and running
In some tests the STL and IGES files exported from Sketchup have various holes and anomalies and come in as meshes even after SU SOLID plug has made them water tight solids
Is there a process for sorting this out, I'm trying the "fill holes" Join, weld tools etc just wondered if anyone had a process
-
Why not try the process 3 posts above with the little prog of conversion?
Sketchup --> OBJ --> 3DM --> Rhino ? -

-
you should be able to import SU directly into rhino. saying that I am not sure if imprter is implemented in beta.
-
Yeah I can get geometry into Rhino from sketch up as polygonal mesh
Is there anyway I can make this into a manifold or start creating the surfaces onto the model in Rhino, I suppose this is what spaceclaim does.....
-
There are some plugins but I believe they are mostly windows for now....
Have a look at here.

Use an emulator, virtualisator...
Or send me your file by PM if not top secret with something like Mediafire -

-
No problem!
-
Just to highlight the limitations, and don't get me wrong I'm a sketchup affection ado
OK here is the panel when I run SU Solid it messes it up, the Round corner plug in looks great but has created many anomalies. Solid inspector finds loads of problems but
I don't know what they are : if you delete the geometry and draw it back it still has the problem and the face has to go there ??The result is that Protomold and firstcut won't even look at it and said that Sketch up files are unusable
Larger manufacturers are more then happy to fix it themselves but when your spending $40 k for tooling I'm sure there notIf anyone can help please
-
Its sounds rough, but you may just have to redraw it in a NURBs based program.
I'm learning Solidworks for this very reason - its usually easier just to start over in a manufacturing compatible modeling app. Luckily I have access to Solidworks at a local makerspace, so I don't have pony up 5K or whatever it costs for a license, but there are cheaper alternatives.
-
BTW, if you need to fix holes in an STL exported from Sketchup, use this: cloud.netfabb.com
Its awesome - just upload the STL, and in a few mins you can download the cleaned version.
