Pattern point to point help?

MichaelPascoe

I'm trying to transform copy a selected face from one point, to another so that I can use it in multiple places. I keep getting stuck on opPattern or transform. Can someone help me understand how to do this?

Here is what I have so far. The opPattern is where it breaks.

var count = -1;

for (var edges in pathFaces)
{
     count = count + 1;

     var point0 = vector(midpointBottomPath0, selectedPathPlane.x, selectedPathPlane.normal);
     var point = vector(midpointBottomPath, selectedPathPlane.x, selectedPathPlane.normal);

     const transform = transform(point0[0] - point[0]);

     opPattern(context, id + "pattern" + count, {
                             "entities" : definition.profile,
                             "transforms" : transform,
                             "instanceNames" : count
                    });

}

Point0 and point are vectors, however, x is valueWithUnits, y is a unitless vector and so is z.

I think you are trying to make point0 and point planes.

line 39
var point0 = plane(midpointBottomPath0, selectedPathPlane.x , selectedPathPlane.normal);

line 67
var point = plane(midpointBottomPath, selectedPathPlane.x , selectedPathPlane.normal);

line 79
   const transform = transform(point0,point);

vector(x,y,z) does not have checks in it for anything other than size > 0 and it is an array.
this will create a plane to plane transform which is likely what you want

The Point pattern custom feature may be of some help:

Also “transforms” and “instanceNames” need to be arrays and “instanceNames” need to be strings. Build the arrays in the loop then call opPattern once.

Thank you @Jacob_Corder, @NeilCooke, & @TimRice

I will give this a try.
