Before first launch

When you first launch the app you will have to wait until it extracts file contents to the device, only after that you will be able to run it (it takes about 30 seconds)

Then you have to allow everything, camera isn't used unless toggled in the Tools menu, it is always disabled when app launches.

Then you will see a spinning sphere click anywhere to enable main menu and then choose an option. Design and present modes are the same for now. By the way this should be the size of the earth if you happen to be in a distance of earth diameter from the center of the earth... And i have made a day orange.

On how to start using app and insert an object follow this: Link

To be able to use camera and prevent application from crashing go to: File>Preferences, scroll down and select any resolution from the list then restart the application. Link

App extracts files to /storage/emulated/0/PEER3DCAD/

After uninstall this directory is not deleted. Keep that in mind.
