I have been trying to use the spline tool for a while, I have tried to vary the pencil pressure , and tried to change between the FIT , & CONTROL. but I can not get an arch. All I get is a straight line. I’m having a similar problem with the line tool , when I use the automatic setting all I can get is an arch. I have to manually change each time I want to follow a shape from a picture.
Hi, Can you please send us a screen recording?
Before creating the recording, please scroll to Shapr3D within the list of apps in the Settings of your iPad and turn on the Tutorial Mode. That will show finger and pencil touches on the screen and it helps us a lot finding out what can be the problem
