Is there a way to create a straight snap at a specific angle in a script? I tried using pointpicker.addStraightSnapAngle(angle, label) but that adds snaps at zero degrees and at every multiple of the angle that's less than 360.

What I need to do is more like adding a straight snap at just 90 degrees without additional snaps being added at 0, 180, and 270.

Doing pointpicker.disableStraightSnapAngle(0); won't work for me because I still want the straight snaps that originate outside my script to be active. Like for 0 degrees, I want there to be a straight snap labeled "x"

Hi Peer,

re:

Just with pointpicker.addStraightSnapAngle() as you mention.

Doing pointpicker.disableStraightSnapAngle( 0 ), pointpicker.disableStraightSnapAngle( 180 ), and pointpicker.disableStraightSnapAngle( 270 ) is the only way set up to do that.

Maybe instead of using straight snap you could set up a custom snapping function. That would be by calling pointpicker.addSnapFunc( YourFunc ); the function you pass will get the pointpicker object passed to it and if you want a snap to be triggered you call pointpicker.setSnapFuncPoint( point, 'label' );

Something like this:

function SnapFunc( pointpicker )
{
   Look at pointpicker.pt or pointpicker.screenpt
   and if you want it to snap somewhere do pointpicker.setSnapFuncPoint( point, 'label' );
}

Thanks Michael for responding so quickly! I'll give the custom snap function route a try.
