Not really, using Freehand instead of Arc is fine, but you can use Ctrl to decrease the number of segments.
Wasn’t familiar with that. Took me a little while, but got it: Option - and Option + on Mac.
Try to export 3d model to Acad and make sections there
I’m afraid it’ll take 3 days
We’re at a transition where interpreting point cloud becomes one of the biggest matters, even though AI will soon enough be able to fill this void.
I’ve been foolish enough to believe in the (rather) new scan essential and sketchup to start with (that I will always attempt to promote around me as I love it), seeing something very promising ; Nobody in our team wanted to be in charge of that and I proudly said I would take care of it, being convinced that I had the perfect tool for it.
Now what do I look like ? it’s been hard enough modeling the whole thing, took more time than expected for technical issues in domains trimble is supposed to be one of the leaders in, and yet I have to tell around for requested documents that after a 3h export there’s still as much work to do on it ? just asking, isn’t there something to work on that should be priority ?
most of the seeked help I’ve been recently reading for the past months are not about how to use the software but how to turn it on, cause you’ve been struggling for years with a faulty licencing management and it still isn’t done yet. I strongly believe there should be a redistribution of efforts
should I say it once more ? don’t build on muddy grounds
oh and by the way, if someone still has a sketchup 8 licence to sell, definitely interested
You will never acheive good results exporting ether 2D or 3D model to AutoCAD format. Sketchup and AutoCAD are Two different platforms. Sketchup is a mesh modeling systen while AutoCAD is a 2D non-parametric drafting system, but it includes parametric drawing tools that allow for constraint-based modeling.
If model will be presented in AutoCAD then the best apporach is to create geometry in AutoCAD as the effort involved in removing the artificats and smothing curves take a great deal of effort. AutoCAD can be used to create 3D geometry which can be used to create 2D layout elements for dimentioning however, imported geometry will not produce the desired result.
Hi Paul,
Hidden line removal in software, which is what is required for 2D vector export is non-trivial to get right. For the on-screen display, we can rely on the graphics cards z-buffer to handle this, and as that is working to a raster output, that can be achieved. For vector output, some other approach such as https://ntrs.nasa.gov/api/citations/19820014033/downloads/19820014033.pdf has to be used.
As to why SketchUp 8 could do it, but not in 2014, in SketchUp 2014 an optimisation was introduced to speed up 2D export for large models, as suggested by https://forums.sketchup.com/t/dwg-export-issue/1796/5: “in SU8[…] The resulting DWG file did not exhibit the same hidden line export problems from SU2014. Albeit, it took way more time for the export but result was perfect”. This switches new hidden line removal logic in when there are more than about 10,000 faces.
I’ve created a model that I think reproduces your issue:
rings.skp (1.1 MB)
If I export Scene 3 I see artifacts in the DWG:
If I export Scene 4, where I have hidden a bunch of the rings to get me below 10,000 faces, no artifacts:
Now that I have steps to reproduce, I will raise a ticket internally with the team that owns this part of the product, but this is buried deep in the bowels of the system so I don’t know how quickly they’ll be able to look at it (and no, it’s not because they have an “urge to meet today’s trend to not miss the AI train”, that is a different team).
In the meantime, if you can do anything in your model to reduce the number of visible faces before export, then this may be a workaround you can use. I appreciate this may not be possible as you have a pretty complicated model, but thought it worth mentioning.
à bientôt,
Dan
