Feature requests for engineering workflow; financial support? (by Alex)
Hello folks,

I'm a new SolveSpace user with background in Solidworks and Creo (formerly ProEngineer). I wanted a low-cost CAD package for basic 2D and 3D design work, without the strings attached to options like the free personal use Fusion 360 license.

For rapid prototyping and small-batch production with single-axis machining and 2D cutting, SolveSpace is so far very easy and intuitive to use. For an open-source CAD package, I am beyond impressed and very grateful for all of the talented contributors.

There are only a few options I find myself reaching for from SW or Creo that don't have simple enough workarounds. I think that with these additions, for my application, SolveSpace could feasibly replace either of those software packages.

- Separate "hide constraints" and "hide dimensions"

- Improved rectangle tool
-> Defined by perpendicularity rather than vertical/horizontal constraints
-> Ability to draw triangles from either two corners or two near points would also be very useful

- Some kind of midpoint functionality
-> Imagine trying to draw the letter "X" at an arbitrary angle, the best way I am aware at present is four legs with multiple parallel and equal length constraints
-> Ability to draw a point and constrain it to the midpoint of a line would make this radically faster

I may have other additions to this list as my experience with SolveSpace grows, I don't currently have SW or Creo licenses to "cross-shop." However, I want to emphasize that SolveSpace provides a level of functionality that I can't get with any other software package without spending at least $500USD per year, and I feel the project itself should benefit from commercial users like myself. QCAD, for instance, has a ~$30 "Pro" license fee which doesn't nearly match SolveSpace in capabilities.

I wonder if there might be a way to give financial support to contributors out of gratitude? Direct donation to individuals, or Patreon?

Could there be room for additional "Pro" modules or add-ons which specialize SolveSpace for one or more commercial applications? These would most likely be GPLv3 just like SolveSpace but GPL would still allow a "suggested donation".

Or potentially a bounty on particular features, perhaps allowing multiple users interested in the same functionalities to fund them?

Thanks for reading!

Alex

Hi Alex, to answer some of your questions:

- Separate "hide constraints" and "hide dimensions"
That has been requested but not added here: https://github.com/solvespace/solvespace/issues/1046

- Improved rectangle tool
-> Defined by perpendicularity rather than vertical/horizontal constraints

I've had that thought myself. You can of course construct a rectangle with those constraints, but to have a button right next to the other that creates it this way might be more useful than I thought.

-> Ability to draw triangles from either two corners or two near points would also be very useful
I'm not sure I understand this one. Can you explain it better?

- Some kind of midpoint functionality
This exists in the constraints menu, or by pressing "m" after selecting a point an a line. To make your "X" draw the two lines, then press "p" and make a point somewhere (not on a line) Then constrain it to each lines midpoint.

If you have other feature requests or issues to report feel free to use github issues here: https://github.com/solvespace/solvespace/issues

I may not say about core devs, but I'm SolveSpace contributor in QA/testing & localizing.

On Patreon I'm sharing my SolveSpace showcases (SLVS-files): https://www.patreon.com/app4soft

Also some of my showcases available on GitHub: https://git.io/DailySolveSpace

To be clear, QCAD is rather different CAD app - it is CADD and is targeted to create 2D drawings (LibreCAD is a fork of QCAD 2.x).

There are a lot of things not (yet!) implemented in SolveSpace which does not allow create really "professional" drawings.

SolveSpace itself could be used for creating some limitied 2D CAD drawings/blueprints with dimensions (see: https://twitter.com/app4soft/status/1348108114596397056 ), but for creating complex drawings (especially according ISO standards) I just recommend use LibreCAD/QCAD; otherwise sketch something in SolveSpace and "Export 2D View... > DXF" - then import into LibreCAD/QCAD for final touches (I has all of those apps installed and using them together).

FTR, QCAD Pro is just a paid trial-plugin bunded with QCAD CE (QCAD Community Edition) while QCAD CE is fully free & opensource, so you can download the binary from site for your platform (see: https://qcad.org/en/download ) and then remove the QCAD Professional add-on running in trial mode (click "Remove" in the "Trial" widget and follow on screen instructions). Otherwise you could compile it from source: https://github.com/qcad/qcad (many Linux distros provides QCAD CE packages: https://repology.org/project/qcad/versions ).
