>> The invaded Ukraine is facing yet another harsh winter. Let’s help them survive! Buy any of our games[1] or DLC between now and December 20, 9:00 CET and we will donate all of our proceeds to People in Need[2,3]
NOTE: If you would like to directly donate to Ukraine needs there is a list of all possible ways to support.[4]
Nice list. It yet complete, but has somes software I've not seen before, such as "Bike-Draw".[0]
One I've found recently is Brent Curry's Linkage[1] bike design app, which looks like a serious competitor for BikeCAD and rattleCAD.
And there are few other not listed in your list SaaS for bike design, I've listed in previous comment.[2]
Also, I'm trying to create own bike design template/macro for FreeCAD.[3,4]
N.B. Reymon Reyes' Bike Builder app (bike parts cost calculator) on your list is not available on Google Play anymore, but its APK could be found on other sites.[5]
> let me know if it can be improved on in some fashion.
Might be good to replace rattleCAD link in the list from official site to Wikipeda article, where there are many rattleCAD related links already collected, including a link to old opensource versions on Internet Archive.
It exists for years, and rattleCAD has been inspired by it — its name is BikeCAD (it also available as a standalone app). Also, rattleCAD has been inspired by Linkage app.
Read Wikipedia article.[0]
Also there are freeware no-login SaaS: BikeGeoCalc[1] and BikeConfig[2].
> If you like Linkage, you might also like Solvespace.
No, I mean Brent Curry's Linkage[1] bicycle design software, not David Rector's Linkage Mechanism Designer and Simulator[2].
You should read Wikipedia article.[0]
N.B. About SolveSpace, as I'm its experienced user[youtube,patreon], I may say next: yes, it could be used for bike mockup, as any other CAD, but it still has a lot of limitations and even does not export correct STEP files yet[3], and in FreeCAD such STEP could fixed only partially.[video]
So, for serious 3D CAD work I highly recommend use FreeCAD (and LibreCAD for 2D CAD work) instead of SolveSpace, and use SolveSpace only as a helper tool like a calc or as a notepad for noting ideas.
About Linkage Mechanism Designer and Simulator, it is only useful for planar (2D) kinematics analyze, and if You are looking an alternative for it take a look on Pyslvs[4], that is in part based on SolveSpace's solver.
N.B. Just a 'reminder', in Ukraine, the "Thwaite" is not a game, its real.[1,2,3]
