Can't draw an axle line.

[Vincent B]

Because there's a seam line above, I can't draw an axle line for this hole.
Suggestion: alloy to delete this line to select the shape of the hole for a centerline.
or any hint?

I wouldn't expect the seam lines to be drawn on a TD drawing. There aren't real edges.

Display of seam lines is usually turned off, but they can be displayed if required.

Sorry, I'm not getting it. All the holes in the picture seem to already have horizontal and vertical centerlines.
You want the line erased like this?

Are we talking about lines made with TechDraw_FaceCenterLine or with TechDraw_LeaderLine or with

Maybe I need to see the file to understand.

Have a look.
On a true drawing, this line must not be here.

Ah-hah!
It's the line in the red box, not the one in the green box!

OCC thinks the line in the red box is a "hard" line, not a "seam" or "smooth" line. I don't have a fix for you in the current version.

In the development pipeline there are a couple of things that would help:
- hide individual lines in the drawing
- make a centerline between two geometry lines.

No ETA for either yet.
