How to use the mdlElmdscr_copyParallel function?

I'd like to use the mdlElmdscr_copyParallel function, but I don't know how to initialise some arguments.

What should I put in point and normal?

From MDL help: If distance is zero, the offset distance and direction is obtained from point. If distance is non-zero, it specifies the offset distance and the direction only is obtained from point

In other words, point is a direction vector that determines where the copy will be created relative to the existing element.  The distance between the new and old elements is determined by one of two methods, depending on whether distance is zero.

Hello,

Ok, but how will I initialize point.

this is what I want have as result

I'd like to copy the yellow rectangle, the distance is equal to 0.5.

So what will a put in point?

Point is a direction vector: try something like this:

DVec3d direction;
//  MDL specifies metrics in Units of Resolution (UORs)
const double distance = mdlModelRef_getUorPerMaster (ACTIVEMODEL) * .5;
mdlVec_fromXY (&direction, distance , 0);
