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 redrawbut hey solidworks is only windows as far as I know.... rhino has open beta for Mac so that maybe your salvation.
-
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.

I thought as much especially as I'm on Mac. I have tried the free Rhino version but it's not the full package and isn't very stable. I have Maya on trial but it's basic modeling is a steep learning curve....
Thanks Anywayz

looks like a cool service I'll give it a whirl thanks

also look at SharkFX8,I had an FX7 extended trial (with full import/export enabled) to output iges files for a pitch...
It worked really well, but I didn't get the job, so didn't buy.
Download the trial, then email the developer [Tim?] and ask to extend import/export for testing, worth a shot.

Driven, you have the right idea. There is no need to redraw.
Download the free and fully-operational 14-day trial version of ViaCAD 2D/3D from Punch! software. Here is a current link...
404 Not Found 2
At Punch!CAD, it is our mission to make computer aided design software that matches up perfectly with your needs, regardless of your industry or expertise. Whether you’re an architect, engineer, CAD drafter, 3D printing expert, furniture designer, student, or DIY hobbyist, you can always find the right tools for the job.
(www.punchcad.com)
ViaCAD 2D/3D can 'import' native Sketchup V7 files and many others including (but not limited to) file types that are important to us like STL, STEP, and DWG/DXF!
So please note...if you are using SU V8 or higher, (until ViaCAD updates their software) you will need to do a SaveAs V7 on your model first or ViaCAD will not import the file. ViaCAD does not warn you when you try to open SU V8. Basically, nothing appears on the screen and there are no failure notices. So make sure you SAVEAS V7 first. SU free version allows you to SaveAs all of its older file formats.
Make sure you check the 'Facets to NURBs' checkbox of the SU import dialog.
Once your model is in ViaCAD 2D/3D, choose Export from the File menu, then choose from the wide variety of file formats, including ACIS (SAT), Adobe Illustrator, BMP, CGM, DWG/DXF, EPS, Facet, FACT, IGES, JPG, RAW, STEP, STL, Text, Viewpoint Media, FRML, and Wavefront OBJ. I only tested a couple of these.
My only minor complaint is that ViaCAD software does not provide any sort of clue when an export process fails. A log file would have saved me some time in determining problems with my SU models.
Basically, this is a fantastic piece of CAD software and the $99 price is well-worth it if you need to export your SU files to a solid-model file type like I did. MAC users can rejoice also as they have a MAC version as well.
ViaCAD appeares to be a highly capable 2D and 3D package for those looking for something affordable. I hope to dig into it more over time. It appears to be well-conceived and even has the push-pull method for shape manipulation that Sketchup help make famous.
Have fun.
Steve
