Whenever i try to use the spline tool i can only add one control point and then no matter how hard i try to press it i cant get another one down. Please tell me of this is a bug or not or if it has anything to do with the sensitivity!

Hello, I think you should change your spline settings.  
First go to spline line.

Make sure that you have selected spline type (Control). Hope this will help. ![image](https://us1.discourse-cdn.com/flex002/uploads/shapr3d/original/2X/5/563675e014428a281f813da3644c330e560dcb6e.jpeg)

No, my problem affects all types of splines and i can’t figure out why i can only put down one spline.

I have had the same problem, sometimes it works sometimes not. I ended up adding a construction plane and activating it. Then I used the line, curve tool to make my spline. I can clean up the geometry a little easier, and save it to a folder in case I need to modify it later. If you zoom out then back in always make sure to reactivate just as a precaution.

my T Spline doesn’t work as well, I don’t know why, but it’s the same as line/arc command… and it’s driving me mad

its '26 and the problem is still exist, BUT!

I’m using shapr mainly on mac, and with a Tablet monitor, and pen.

With the pen the bug is the same as you described, and constant, so it can be repeated. I really not understand why the Fk is the pen not supported by default on a mac environment… I mean come on, it is by default tailored to a tablet…

So if You have the same issue, You have to click with the mouse button. that is My ‘‘solution’’ ATM
