vlax-curve-getClosestPointToProjection returns inconsistent results

[IToastThereforeIAm]

Hi,

How can I ensure that vlax-curve-getClosestPointToProjection returns the closest point in every case? I suspect that the curve is merging in the projected plane and therefore it does not always return the closest point in the desired direction.

Alternatively, I could probably use vla-IntersectWith method with a line object and find the closest point, but I'm using grread where vlax-curve-getClosestPointToProjection will be more appropriate, I don't have to create and delete line objects in while loop.

I Really need to start using grread and grdraw more. seen some really nice things the past few week on here. what happens if you take out LM:rounddown function call?

 

-edit

i haven't run the code but might be something in the (if (< dst dse) that isn't updateing the cpt point correctly. that is making "outside" the other line.
