A Fediverse community for open-ended, thought provoking questions
Rules: (interactive)
1) Be nice and; have fun
Doxxing, trolling, sealioning, racism, toxicity and dog-whistling are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them
2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com.
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.
If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email info@lemmy.world. For other questions check our partnered communities list, or use the search function.
6) No US Politics.
Please don't post about current US Politics. If you need to do this, try !politicaldiscussion@lemmy.world or !uspolitics@lemmy.world
7) No Hit-and-Run questions.
Please don't delete your post for no apparent reason. If you plan on deleting a question later, say so in the post, or if you feel that you have a good reason to remove it, message a mod beforehand. It's not fair to the ones who took their time to answer, and it's not in the spirit of the community.
Reminder: The terms of service apply here too.

How does this compare to FreeCAD or CAD in general?
It's very unique in the CAD space. It's almost more akin to a hardware definition language like VHDL than it is a traditional CAD solution.
You don't ever do any direct manipulation of your model through visual tools. There is a visualizer so that you can see your model, but all changes are done via plaintext editing of the model's definition file.
This has a lot of advantages, not the least of which is being able to version control your 3D models.
It has some disadvantages as well, in that some transforms that are easy in a traditional CAD software are a little more manual in OpenSCAD. I've definitely had to dust off my highschool trigonometry once or twice to get something the way I wanted it.
Specifically with regards to FreeCAD. I found FreeCAD to be a little inaccessible. It's unintuitive at best, and I found it unpleasant to work with, as it was exceptionally fiddly. OpenSCAD feels far more intuitive to me, but I also have a software engineering background. I think OpenSCAD may be trickier for someone without that, but it's hard to say.
Thank you for the thoughtful explanation!
