long story short: I was looking for a quick tool to “trace” paths over bitmap images AND doing it over the sofa in the evening
…so I made up this application to allow me completing the task,
the goal was to make this application as quick, intuitive and handy as I could,
and while coding I kept adding more features to make it more complete and powerful, it’s now almost a (very basic) 2D CAD.
It natively exports to DXF so you can easily import your files into Sketchup Pro (and I think there are extensions to import DXF files anyway).
Once imported into Sketchup, you can “create faces” filling your line drawings to easily pull up 3D walls, or intersect the lines where you need, or whatever. WIth features like “grid” and “snapping” I think it could be very comfortable to lay down simple floor plans. The app is meant to be used on a tablet with a stylus and “palm rejection” option enabled.
The package below contains both the Windows version (mostly for evaluation purposes) and the Android version, plus a very quick documentation PDF:
The fact the app is tagged “free” means it’s free for commercial and non-commercial use, and it also means there’s chance for a future paid version with many more features for a very small fee, but it depends on the interest it gathers and my available time (and my migraines :D).
Thank you for your attention and sorry in advance in case this is not the correct place to post this / not conform to forum policy / not relevant for anybody.
Note: if you are going to export for Sketchup make sure you tick the option “Export 0 thickness lines” in the “Settings” window, otherwise Sketchup will make “vertical faces” of “thickness” height.
Note2: (limitation) it won’t handle more than about 18000 segments
