I have an iPad Pro with iPadOS 18.1.1 and Apple Pencil Pro. Granted, I am a newbie to CAD and 3D Printing. I want to create models for printing with my Bambu P1S and am starting to get the hang of using Shapr3D on my Windows desktop with a mouse. But, I’m having problems using my iPad and Apple Pencil. For one, when I go into Sketch mode and select Rectangle and point and drag the pencil, I either get the selection or nothing. I’ve tried not holding the pencil too long to start, but I usually have to tap at least twice to get the rectangle and that may be after a few tries, having gotten either the selection or line drawing. Also, I can’t figure out the equivalent to shift-selection (to select multiple objects). I searched all over Google, shapr3d.com and the community forum for instructions for using the Apple Pencil with Shapr3D no luck. It would be great to have a tutorial and/or list of functions and how to use them. Thanks
Anyone have any suggestions? 
Hi Mark,
My guess is you need to be just a little quicker moving the pencil after locating the start point. If you get the selection tool, then there was too long of a pause before moving. But if you have selected the rectangle tool, you should either get a rectangle or the selection tool. I don’t know what “nothing” is that you mention.
To select the first, tap on it. So it makes a difference if you tap an edge or a face. Or if you want to select a body, double tap it. To select more, you select a second, third, etc., and they will be multi-selected. You do need to be careful; if you miss your target so you are essentially selecting nothing, then you deselect all.
Also, there are some areas where you can’t sketch. If you’re too close to a tool or other icon, it won’t trigger the sketch tool.
Some things that may help… Zoom in enough so you can easily hit the start target; if needed you can zoom out during the sketch using pinch gesture of hand not holding pencil. Practice making a bunch of shapes in the center of your screen to get a good feel for the timing issue.
Hi Bob,
Thanks for your helpful suggestions! I will give them a try. Basically, it looks like an issue of dexterity–which I may be lacking.

My biggest qualm about Shapr3D Apple Pencil support is that actions are too time dependent.
