I scrolled with the mouse wheel and the origin drifts off screen.
Is there an open-source "cleanroom" re-implementation of the Parasolid kernel? I just like the way Solidworks does things vs. Autodesk.
If you get lost press `f` to "fit" the current drawing to the screen.
By the way working in SolveSpace is extremely fast if you use keyboard shortcuts - almost everything can be dome with a shortcut key. No need to search for them - you can learn them by looking in the menus.
A very short "crash course" on the navigation is in the "Quick start:" section at the bottom of the download page. https://solvespace.com/download.pl The "demo video" on the home page is also a great starting point.
After that the "Tutorials" and "Reference" go in as much detail as one may want :-)
This is expected behavior. The zoom action is into the cursor center. This is the same behavior of many other 2d/3d editors, such as Autodesk Autocad, Inventor, etc. Even MS Paint does this. If you place your cursor perfectly at the origin, it will not appear to drift.
The mouse wheel zooms. The bounds of the axis stay fixed on the screen however. It will become more intuitive if you draw a circle to the screen first.
To pan around the space, use the right mouse button. To zoom, use the scroll wheel. To rotate, use Shift+Right mouse button.
Why not play with it a little bit before dismissing it so suddenly? I don't need to mention to a Solidworks/Autodesk user that CAD tools take some patience to understand properly :-)
