Set (Part design)axis as direction

[Jee-Bee]

When importing step files it opens by default in a Part design structure. So if possible can anybody add a featuer request on mantis??

I may miss the whole problem

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


Please add a FEM analysis and try to mesh marked part

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

AFAIK, whole stuff is postponed to 0.18

Hi UR
for the moment you may use Kicad StepUp WB to get a flatten copy of the Hierarchy
(I modified the Deep Copy macro to have a copy of the shape with a standard flat placement)

I have found another part design(?) FEM flaw.
When a stp file exist out multiple parts it is imported in a part structure.

But when creating a mesh it is inposible to do this at once... I don't test it s i don't know if it it possible to so solve. at least it is annoiing when it containts out 10 or more parts

As a workaround, ATM, you can use DeepCopy macro...
It makes a compound of all Objects in Parts container, and you then should be able to make a FEM analysis on the compound object obtained from the macro.

Thanks i download it and use it from now on.
But still i think this need to be done (maybe in tracker) it is weird that a macro is needed to fix a flaw in FC itself

I agree so much...
I already did a ticket here (on Feb 2017)
https://www.freecadweb.org/tracker/view.php?id=2905

You may chime in there or open a new ticket...
This feature is also a must for 3D printing (make a STL of the hierarchy), or as you noticed, for meshing.

It could be included in FEM WB or in Part DN WB as a menu entry or better a button of the WB.

Just a side note... the link to to the DeepCopy Macro is broken from the add on manager in 0.17. I get a message something like unable to fetch ....

you need to rise an issue at github for DeepCopy macro or Addon manager or both.
