Set (Part design)axis as direction

Postby Jee-Bee » Sat Mar 17, 2018 5:11 pm

I have the situation that i want to add a force in the y direction but my model don't have any edges on it or planes thru it...
Would it be possible to set axis from part design in the direction option?

just create a line in the direction of your need with Part --> primitives tool

AFAIK you can make lines with PDN too https://forum.freecadweb.org/viewtopic. ... 36#p221331

True but a line is for normaly geometry related. A plane or an axis are references (for the geometry) and since references are kind of stable i prefer to use them.

If you would like to use an element from your geometry than you should make sure your geometry has an appropriate element.

It would be cool to use the 0.17 PartDesign Datum stuff, but that's for 0.18 IMHO.

The funny part is: PDN uses hierarchical placements from so called "tip" to root.
They have to be lined up, walking the whole chain of links.
Also DraftWB isn't PDN ready ATM.


example:
as1-oc-214.FCStd
(160.28 KiB) Downloaded 15 times

Please add a FEM analysis and try to mesh marked part

Gmsh does some movements and flipping :o
netgen destroys hierarchy by pulling part out of body :shock:

AFAIK, whole stuff is postponed to 0.18 :?

What stuff? draft WB
At least FEM since it is unknown...
