Sketchup Can 39;t Import Dwg

[Maria]

Iam trying to import a Sketchup file into Vectorworks 2016. When I use "Import Sketchup File" and click on the chosen file, nothing happens. The Sketchup settings window doesn't open, and nothing imports. There isn't an error message, just nothing. The file window closes and I return to my Vectorworks screen.

I think it just showed up blank for me at first, too. The drawing was "north" a little bit. I wonder if you try it again and hit Command 6 you might see that it really was there. Just further away from 0,0 than you expected.

I believe if you have VW 2016 the Sketchup files have to be from 2015 or earlier. I'm not positive, but I believe that Sketchup 16 was released a few months after VW 16. So there is usually a 1 year lag.

After the import finished I managed to save the file. Then I had to restart the computer to make it useable. Just reopening the file took 32GB of virtual memory. It struggled, but it was finally able to export to VW 2016.

One thing I've occasionally found when importing SketchUp objects is that a single SketchUp texture might import into Vectorworks as hundreds or thousands of separate textures, one of for each polygon in the model... depending on how it was originally mapped in SketchUp. This has severely slowed otherwise simple imports. This may or may not be related to the issue at hand.

I the sketchup file has materials attached to each individual mesh triangle inside the group, as opposed to all the meshes and line to have the default material, and the whole group or component painted with the selected material.

Then i tried to import the collada file into blender, i opened it in blender, export it again into collada file(.dae), and it works!, i can show it in THREE.JS but there are missing objects, but i don't know why

Do this first: " in SketchUp, select View > Face Style > Monochrome to see whether the back sides of a any faces point outward. By default, the face fronts are white and face backs are dark gray. To reverse a face, context-click it and select Reverse Faces. If you use Solid Inspector 2, the extension can find and fix the reversed faces for you." In essence you're making sure that all your faces face outward. Inward facing faces would be invisible unless the camera is inside the model. Check your output in Three.

If that doesn't work, I have had issues with fragmented export from Sketchup2017 just recently. Save your skp file in a folder that is not on your desktop or a network folder. Close the file, close sketchup, reboot your machine. Reopen Sketchup, open the skip file. Select all objects and copy. Open a new project and paste the objects. Save as a new skp file, Select everything you want to see in your obj or dae file and group them. Choose export to obj or dae. Test in Three.js.

Same problem Here... Still looking for a solution. I could just import sketchup models into Archicad and keep as they where imported, but every time I export to Lumion the textures are renamed and they lose ther settings.

1.

Is there a way to "name" Groups (Component ?) in Sketchup.

That may help Bricscad to accept them as "not-so-anonymous"

and even accept them as Blocks.

At least Vectorworks tries do do so when chosen in Export Settings.

For me Bricscad IFC import is very good and IFC in general is for me

one of the best or most lossless conversion option.

Still lots of cleanup and rework needed.

So normally I try any possible exchange format and in the worst case

I try to mix the best results from all into my file.

I think Sketchup has tons of Plugins, maybe some can also help for

exchange.

Maybe a second Translation Software in between that has more

lossless Sketchup import and export options more suitable for Bricscad.

Maybe some of the authors of the Sketchup Files could be persuaded

to try Bricscad Shape instead. OK, that's not the same in many ways,

but would be perfect for Bricscad BIM.

I have been working with sketchup for years now now and the benefits (speed / visuals) of 3D modelling and materials in sketchup are still important for us, at least until Shape can add customizable material maps (material management as of now is very basic).

I therefore have been trying to test a reliable import process from sketchup to Bricscad.

I get at least a few Layers in for further separation.

I get Materials in (although I have never seen them assigned in Bricscad so far)

I get geometry in mostly as proper Solids.

If I get some Meshes in that may have been only Meshes before, they unfortunately

get some extra unnecessary tessellation (or they were corrupt already)

And I get all spatial elements and locations and BIM Tags in Structure tree.

Revit import gives no Layers,

no Materials (not sure if that is as designed),

some geometry missing and some destroyed L or T-connections

But at least also Solids, BIM Tags and Hierarchies ...

DWG would be the best import into Bricscad.

Unfortunately I get DWG only for 2D Plans. DWG got quite unpopular here.

While in the past DWG 3D was used mainly as an exchange between non Autodesk

Apps, with questionable quality. Meanwhile most switched to IFC instead.

Importing into Rhino and using its cleanup and remeshing tools may solve some or most of the mesh issue you get from importing Sketchup files. Once the cleaning up has been done you can then export to DWG or import the Rhino file. I used this route for getting triangulated 3D dwg files into Vectorworks as that gave a cleaner result than directly importing the dwg files into Vectorworks.

Maybe it will work as well for Sketchup files.

SimLab composer is a 3D rendering program but it does import geometry quite nicely most of the time, though I haven't tried with Sketchup so far. You can download a trial, import one of your problematic Sketchup files into SimLab composer, if it looks ok then export to DWG and see what happens regarding geometry and what is retained regarding properties etc. Maybe you'll get cleaner files into BricsCAD that way.

And I have to update my Revit vs IFC experiences.

It is not clear what brings in more Solids.

IFC has better L/T-connections while Revit brings in Solids where

IFC has extra tessellated Meshes.

All Strange ....

This plug-in no doubt can import sketchup model to CAD. But when the model is called in into the CAD software, the model scale is messed-up. So basically you can't do anything on the model except you have to re-draw again. But, I found in the sketchup software, you can actually to EXPORT the sketchup model into CAD model and the scale is still same from the original model.

I imported a 2021 Sketchup into AutoCAD 2023 and it works fine, no issues. It imports and turnes it into a block. I wish it would list all the blocks its importing, give us the option to choose which blocks to bring in, and also give us the option to smoothen meshes of some of selected blocks.

There are several possible issues.1. SKP file version is beyond 2014-2019. (You can save the SKP file to a version supported by the app)2. SKP file path contains non-English characters. (You can update the path to contain English only characters)3. Some other issues...
