Hi Pilou,

> And I don't know where is the middle of the path ;)

Well if you want it to be placed in the middle of the path the default sweep will do that - for the situation you were talking about it sounded like you wanted to move it to somewhere else other than the middle of the path. If you wanted to move it somewhere else other than the middle, then why do you care where the middle is?

You can find the middle of the path by placing a point object at the start of it and doing an array curve to duplicate it at evenly spaced points along it.

They actually are - you may see a little tiny bit of solid looking curve poking out from them, but that is just a display artifact. Part of the process of drawing curves is that they are pulled forward a little bit in depth so that a curve that is on a surface like an edge or something does not get drawn partially submerged in the surface. That little bit that you see at the end is just a side effect of that pulling forward mechanism.

The realtime display has to make various compromises in order to be fast, so it's not generally possible to get pixel perfect results with it. You just need to ignore some small little display glitches like that.
