Ratings and reviews

Great app! Can't believe this is free. So many tools I've probably used less than half of them. Some things I'd love to see: Dark mode. Please, my eyes! More customization, such as saving multiple custom settings, and custom tool groups. Ability to minimize the tool menu while still using a tool! More integrated layer functionality An easy way to redefine an object by it's position, staying in the same place but detaching from any connected construction

I don't see what this is for, can't find any actual helpful functions. Some menus can't be accessed because they are placed under the phones basic menu buttons, so maybe that's the issue. Really awkward UI overall. Can't set or even see values (those options seem to do nothing) so how could I do anything?

extremely clunky interface. lost a huge project just because you can't manually input coordinates.

What’s new

• New feature: Autocomplete, which makes using commands easy and straightforward.
• You can now take pictures with your camera and insert them into your constructions.
