Ik want to Export a 3d model in DXF or DWG format but Sketchup stops every time I try.
Is this a known problem? and more important: is there a way to solve this?
you have surely restarted your system already?
do all documetns even simple ones cease to export?
you may want install/run ThomThoms CleanUpĀ³ plugin (āWindow > Extension Warehouseā¦ā).
You might have a corrupt SketchUp Preferences file, and deleting it would force SketchUp to create a new, clean one. I donāt use a Mac, so I cannot tell you where to find the file.
On Mac it is called :
com.sketchup.SketchUp.2017.plist
it is located in :
Macintosh HD/Users/Username/library/Preferences
the library folder is hidden, so , in Finder-> Go->Go to Folder and type destination
Gebruik je de 3D Model optie of 2D Graphic?
Are you exporting the 2D graphic or 3D Model ? How large is the file ?
Like @sketch3d_de suggested :
Does this work ?
Thanks for thinking with me.
System is restarted. I couldnāt find the preferences file (even with the hints from Mike) but I found out that, with another simple cube I can export a 3d dwg file. SO it seem to be that the problem is in the geometry.
What I could do is save a copy, then deleted components one by one and try exporting again after every deletion to find out where the error is.
This can be simple, or can be time consuming. good idea?
Or the amount.How large is your SU file ? Can you share it here ? Are there any 3D warehouse components ?
Try deleting half the number of components.
The file is 3MB in size. The whole exercises is to make models of our products available for customers on different platforms. So there is no problem sharing it here. Although it is not finished yet.
Sunbeam modellen.skp (2.8 MB)
I couldnāt find anything strange, but maybe one of you does. I think deleting geometry one by one to find out where the error is, is the way to go now.
With this relatively small file it isnāt a big deal. For larger files it would be good to have a more efficient way to find where te error is.
I think I have found the culprit, there was an unnamed definition. After renaming it and toggled some options on in the export , it exported fine.
Here is the file :
Sunbeam modellen1.skp (646.5 KB)
and the export :
Sunbeam modellen1.dwg (664.5 KB)
have fun! (in the ā¦)
The āoutlinerā window is useful. Never found it before. Thanks!
In the end I had to delete the piece of 3D text you found and then the model exported again. Thanks for the help!
Strange thing is: I redid the 3D text which was deleted. In the original model it shows 1 component in the model. When exported to DWG it makes 3 instances of that component at random places in the model. No idea why.
Export report said all is fine. Maybe Skecthup is fine with randomly distributing components in my model, I am not so fine with it actually.
Itās not that this model is so complicated. Is SUās dwg conversion so buggy? or am I doing something wrong?
Wait: i will share the docās again:
original SU model: Sunbeam models.skp (680.8 KB)
model after export to DWG and import to SU again. Sunbeam models -DWG import .skp (575.5 KB)
there are a few thing I can 't solve:
Edit:
i tried fixing the first Bug so at fist deleted the āuniversal 1270ā 3D text block. and thenā¦ The other component (Sunbeam Nova Symmetrical 2100 ) which never had an issue but somehow got into a group with the 3d text, now is connected toā¦ another piece of 3d text?! I am completely in the dark here.Why does SU randomly makes groups when exporting to DWG? Sunbeam models -DWG import 2 .skp (459.1 KB)
Glad it worked !
When you redid the component, did you purge the model first ? Sometimes the āinternal databaseā of the entities (Component definitions etc) in Model need to be cleaned up. I frequently purge the model when making components, renaming, etc to keep the file ācleanā. Remember : every component you ever made or imported is still in the āIn Model collectionā in the component tray. Window->Model Info->Statistics purge unused takes care of that. Or click the little detail icon in the components tray.
Edit : by default, 3D text comes in as a Component with the text as Definition and Description. So , especially when you are on a Mac and try to edit the Definitionās name in the entity info, you could wind up with ānamelessā definitionsā¦
Hy Mike,
Since I found the purge unused button I purge all day long
Now I redraw the āSunbeam Nova Symmetrical 2100ā component (purging before and after) 
and now that part is fixed. All text blocks are exported and no strange random groups are made. I am still curious how this occurred, but anyway: for now it is good itās solved.
Then there is still the colour issue. Any ideas?
Most likely you are aplying colors on the āBackā side of the face. SketchUp is a (flat) surface modeler and a face has two sides : Front and Back. In the standard templates, the front is white and the back is grayish blue. If you are drawing a face on the ground plane, its normal is down, so we are looking at the back of the face ( the inside of a box, when the face is pulled up) With the export reversed faces it is likely that things turned badā¦
In Sketchup, edit component, right click on face and choose āreverse facesā then apply color.
Notice when you have 3D text set to 0 extrusion , the faces of the text are also reversed.
Most of the time , I have set the back face color to a more distinctive one like orange or green in my style settings ā¦
The next step would be to put the different representatives of your components on their own layers. Then Put them all together for one product and make a āshellā component. This Shell component can be applied with different attributes in the Dynamic component attributes dialog. Things like price, availability ,website urls, etc can be added and seen by the user or listed in generated reports.
haha, that last part sounds one level up for me
I know the reverse faces function and was busy reversing them to get a good export. Result:
This is super annoying. How on earth is it possible that a file exports correctly, that i change faces of component A and on a new export SU messes up component B and C
The problem must be in the āSunbeam Nova Symmetrical 2100ā component, although i completely remade it already. And I know it is probably my fault. But it is super annoying that there is no way to find out what is wrong.
Edit: i have redrawn the āSunbeam Nova Symmetrical 2100ā component again. And luckily everything exports again without making strange groups. Men I would be happy to find out what happened here. And how to prevent it from happening again.
Thanks to many advice here the file is now ok for export to DWG. Ik took me a few versions an attempt. but: cool! thanks.
Now the next step: export to IFC. new topic for that. (and is Mikeās last comment not already the beginning of that?)
