(WORKAROUND) Unexpected behavior of polar array on not top workplane?
is there a possibility (possibly a workaround) to create a polar array on an inclined plane?

I've found a way, tomorrow I will create a video about it

Re: [solved] Unexpected behavior of polar array on not top workplane?
Strange workaround. Why not create the array on the global XY pane, create a Std_Part, put the array in the Part and then transform the Part? If Std_TreeSyncPlacement is switched on you can then drag the array out of the Part if you wish.

Re: [solved] Unexpected behavior of polar array on not top workplane?
yes it is usually better, it is only an example for e.g. this case. I would like to create a polar array on the connection that is inclined in the room.
Re: [solved] Unexpected behavior of polar array on not top workplane?
It depends on where you are starting from. But exporting to STP does not make sense IMO.
If you start from two co-planar circles randomly positioned in 3D space, where one represents the center of the array and the other the item to be arrayed, I would use this workaround:
If you start from two co-planar circles randomly positioned in 3D space, where one represents the center of the array and the other the item to be arrayed, I would use this workaround:
- Create a Std_Part.
- Right-click in the Property editor and switch on "Show all".
- Right-click the Placement field of the Part, choose "Expression...".
- Reference the placement of the "Center" circle: <<Center>>.Placement
- Make sure Std_TreeSyncPlacement is switched on.
- Drag the "ToBeArrayed" circle into the Part.
- De-activate the Part.
- Select the "ToBeArrayed" circle and create a Draft_PolarArray at the global origin.
- Switch off Std_TreeSyncPlacement.
- Drag the array into the Part.
- Switch on Std_TreeSyncPlacement.
- Drag the array out of the Part.

Re: [solved] Unexpected behavior of polar array on not top workplane?
that sounds good. i work with a translator, that makes it a little difficult. is it very time-consuming if you shoot a video of it?
edit
I think I did everything as described, but it doesn't work for me. have you tested it or is it a theoretical suggestion?

Re: [solved] Unexpected behavior of polar array on not top workplane?
I tried again and shot a video of it. the centering does not fit, what am I doing wrong?
