<div dir="ltr">Correct, I was thinking more PC_Transform(pcpatch, pcid), which would look for common dimension names and map between them by default, or could maybe accept a mapping (dim->dim) to control the conversion.

<p>Ah. Yes, I think if you are accessing a point within a patch, you have to unpack the patch. It's one of those tradeoffs...<br>

<div dir="ltr">Now the only solution I found is to break a patch into point, then break point into attributes,
<br>
then construct a new point with correct pcid and attributes, then construct a new patch !<br>
