TechDraw Page Select Face For Hatch Issue

[mendy]

Am not able to select certain faces on Isometric view on page to add hatch (simulated knurling). Can select some faces. Created simple file of washer shape with padding. Also tried with same washer using revolved sketch. Same results in both. Did find the settings in preferences which were set as shown.

Had what I think is similar issue in this post which is similar as my template with grid showed through and was confirmed.

https://forum.freecadweb.org/viewtopic. ... 93#p333293

Used FreeCad USLetter_Landscape_blank.svg template in the attached file and just switched to my grid template on my system and grid shows through most of Isometric View.

Can someone confirm?

Additional information turned off Detect Faces in preferences and no faces are selectable.
Also with Detect Faces on it the Top View the center hole shows as a face but in 3D View only the washer face is selectable, not the center hole.

I confirm the issue. Interestingly changing the Rotation of View to 90° makes all the faces selectable.

Thanks expanding on your findings I rotated the sketch 90 degrees with no change. Rotated it 180 degrees and all faces are now selectable. But strange on Page Isometric View the seam line changes but faces not selectable. Add another Isometric View and it's faces are selectable.
Seems to have something to do with arcs or circles. Will have to go through my drawings to see if it happens on non circular items. Just noticed because I wanted to try hatch to simulate a knurl pattern.
Did look at partial file in progress and most faces are selectable. Was working on blank template and loaded my grid template and non selectable areas show the grid below. Will have to play with sketch rotation on that one, probably won't have time right away.
