Hi Andras,

> You have "Cap ends" but I have not "Cup ends". Why?

The "Cap ends" option will be hidden if there is not at least one closed and planar profile curve.

So possibly the points of your profile curve have been disturbed slightly in z so that they are not flat planar curves, or they are not quite all the way closed.

Ah, well probably these projected curves are not planar - that's why no cap ends option for them.

At some point in the future I would like to try to automatically cap more complex ends, but it will be a while before that will be possible.

I understood
Thank You!

Ok,
Here very simple examples for "cap ends", (results surface only)
Useful or not`?, possible in conjunction with other Commands

(StraightSnapON, ObjectSnapON)
TrimCommand__Add trim points__Done__select new edges__use BlendCommand "value 0"
(observe seam, there must trimpoint get set, other trimpoint opposite)


TrimCommand__Add trim points (4points added)__Done__select new edges__use NetworkCommand (observe seam)


two trimed edges + line__LoftCommand used



SweepCommand used__edges is profil__middle line is rail (ShowPointsON)

__SweepOption End: PointyEnd__after "Done"

__Top most point selected__ moves to middle
