Elegantly Simple and Rubust Technical Drawing App

When I finally returned to the Apple platform, I focused on finding the right apps to assist my journey in teaching myself how to draw better... while there are plenty of powerful full color art apps with deep brush tool libraries, I kept my eye out for an app that offered something along the lines of CAD drafting without being “too much“ for my actual needs. This little gem is packed with powerful, user friendly, and unique technical drawing tools. Not only is it robust and accurate, it is offered at what might very well be the most competitive subscription price point on the iOS app market. My one and only complaint is that there is no macOS desktop version of this app. I love the functionality of this iPad only app as it is, and strongly recommend it to anyone interested in simple architectural sketching, line art, technical drawing, logo creation and similar creative tasks that do not require complex color or texture brushes. But I humbly and enthusiastically encourage this developer to bring this app to the desktop environment!

Still too early to tell if this is for me but looking better

After buying the drawing pack, after careful reading discovered how to make drawing work. Quite frustrating that this detail was omitted from an otherwise almost too clear built in help. Oh well. Now I can give this app a run for its money. Will take a few weeks. My use case is a rare bird.

This application is absolutely perfect use as a municipal Police Officer.
I recently needed a diagram drawing for an accident I worked but didn’t have access to the normal program.
I found this program and fell in love with it. I’m able to draw roads, alleys, vehicles, signs and label different sections of my scenes.
I love the binder option. I can create vehicle types in one binder and signs in another as well as copy, paste and rescale them.
Thank you Siemens for an excellent product. I look forward to future updates on it.
I would love to see an option to automatically scale my drawings to 8.5x11 for standard printer paper.
