Title: Can't trim 2 splines
Post by: Karol on May 08, 2019, 08:31:17 PM

On R13, these 2 splines (one is a straight line) can't be trimmed with one another

Planarize spline and line and then check for intersection using intersectwith method... If it returns point coordinates, it means there is intersection... Then, I suppose trimming will be possible - not tested though...

Intersectwith method :

Code: [Select]

(vl-load-com)
(vlax-invoke (vlax-ename->vla-object (car (entsel "\nPick LINE..."))) 'intersectwith (vlax-ename->vla-object (car (entsel "\nPick SPLINE..."))) acextendnone)

The main problem here is how to planarize 3D entity - SPLINE with 1D entity - LINE... Well You could try using OSNAPS : command MOVE, pick point on SPLINE with "_nea" OSNAP and as destination point pick point on LINE with "_nea" OSNAP... If SPLINE is 2D they will be planarized, but if it's 3D, I suppose you could be able to trim one side from intersection point and the other side should remain IMHO...
