(2019.0) comp(f) breaks pipe geometries

[LR]

When I try to comp pipes, the geometry flies apart despite nothing telling it to do so. Is this expected behavior?

Here's the rule:

@Range(true,false)
attr Comp = true

@StartRule 
 Lot -->
 	case Comp == true: comp(f){all: X.}
 	else: X.‍‍‍‍‍‍‍

L R‌ - Does the result change if you use?: 

comp(f){all = X.}

Even if so, that is weird. Are shapes translating?

[DavidWasserman]

Is it creating new shapes or moving the old ones? It almost looks like floating point precision error when it resets the the shapes...how small is this pipe?

[LR]

Only the successor shapes move. The original does not move. The pipes are 25cm across. Operator "=" doesn't have the error which is probably because no position calculation happens in that case.

This is unexpected behavior, and I suspect it might be due to precision (or maybe even non-planarity).  I can't reproduce it though.  Would you be able to post your scene file please?

[LR]

I would pm it, if I could.

Looks like a precision problem.  We are looking into it.  Thanks for reporting this.
