aeclineworktrim trims wrong side

[dhallett]

When I use the lineworkshrinkwrap command on a single block to create a polyline, and then use the lineworktrim command, the side that is selected to be trimmed remains and the side selected to remain gets trimmed. If multiple objects are selected to create the shrinkwrap polyline, the resulting polyline trims as expected. I am using this as part of a sequence of commends in a lisp routine. Anyone have any idea why this might be happening?
Thanks.

What version of ACA are you using?

I just tried this in ACA 2010, and had the opposite experience. For the polyline created by AecLineworkShrinkWrap by selecting a single AutoCAD block reference, the LineworkTrim command removed part of the polyline on the pick side (leaving the portion on the opposite side). For the polyline created by AecLineworkShrinkWrap by selecting several overlapping AutoCAD block references, the LineworkTrim was trimmed on the side of the defining line opposite the pick side, leaving the portion on the pick side. I would have expected that the pick side would be trimmed away in both cases. I also drew a polyline and used the LineworkTrim command on it; the part of the polyline on the pick side was trimmed away, leaving the polyline on the opposite side of the defining line, as expected.

I tried this using the LineworkTrim command on each polyline individually, as well as selecting all three polylines at once, and got the same results either way.

I have no explanation for the difference in behavior.
