Lattice2 AttachedPlacement Error

Post by nefarious »

I have a body that I want to use AttachedPlacement to combine several instances of a different body to.

I have done this several times before, but for some reason I get an error message 'NoneType' object has no attribute 'isDerivedFrom'

BothShowing.png

An image of what both objects showing looks like. The placement arrows are in the correct place and in the correct direction.

To make the Attachment the Stake body is the active body, it is highlighed
Then a combined select of the following in this order:
The Attachment is selected
The AttachmentPlacement is selected
and the Stake PlacementSequence is selected

and in the Lattice2 I choose Lattice PartDesign Pattern

Any help on what could be wrong?

Maybe the Lattice2 author @DeepSOIC might comment.

Hello,

I had a somewhat similar issue when I was working with another tool. What fixed it is that the body has
to be unselected (un-bolded) but still highlighted. Double click on the active object to un-bold it then
select it without bolding it.
