Scale non-uniform along vector?

[TIG]

the group is from its untransformed bounds [from a temporary instance of it added to the face.parent.entities].

You know how long the 'edge' is [edge.length] so you can work out the ratio of the two values...
Now you can use that to scale the group.entities with a scaling-transformation along the xaxis only... and thereby the original group is scaled as needed.
Erase the temporary instance of the group to tidy up...

Yeah, thanks TIG. All what you say is true.

All these transformations got my head spinning. So I ditched the scaling in the tilingmethod. Went with scaling(y in this case) at ORIGIN, just after loading the component. Before placing it on the face. Not as flexible as in a method, but it will hopefully work. I think Dan suggested something similar, earlier on in this thread.

Maybe that's what you had in mind all along as well, TIG. I just coulden't see it then..

Edit: When I reread you thread, did you mean to scale entities and that would become a "local" scale? Cause i did some scaling in x or y and it was in fact a global scale. The group moved from the face and tilted, even when putting the origin at center of bbox. I can't recall 100% sure if it was the group OR the entities I scaled. Ah heck. I'll try tomorrow then.. Like I said, rather had this transformation separate in the tiling method..
