Ratings and reviews

one thing is missing. or has error in it. when rotating a point about another point clockwise or anticlockwise there is only the option of rotating in degree. not in ° ' ". hence converting DMS in Degree truncates the small value of seconds. I want that feature in this app. please as soon as possible. thanks. I am a civil engineering student by the way.

Using relation on anything crashes the app, i dont see any use if the line lengths are forced to be defined

Why did you remove the 'Show / Hide Label' option from the general settings ( Not the graphics settings ) ? I now have to manually Show / Hide labels. It would also be nice if I could resize the toolbar ( adjust how much of the screen it takes ) as can be done in the online version.

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.
