Commands with shift ortho constraint

Hi All,
I am trying to check if in the RhinoCommon SDK there is any automatic way to have a GetPoint that accepts the shift modifier key to constraint the input along the ortho direction (as the Line, Curve and other commands do).

Do I have to implement this myself?

Thanks a lot

Hi Alberto,

Well this should be on for all new instances of GetPoint. But you can set this explicitlly by calling GetPoint.PermitOrthoSnap. Note, ortho only works if you set a base point using GetPoint.SetBasePoint.

Does this help?

That’s a good tip :wink: we are not setting the base point in our command, that was the missing step.

Thanks a lot Dale! Have a great day
