Constrain Components feature problem

aleksei_ovsienko — Tue, 22 Jul 2025 11:25:10 GMT

Hi. Now either I misunderstand something about how this constrain components feature is supposed to work, or something isn't right. Every time I try to constrain a component in all three directions I get an error saying there are conflicting constrains.

Here's a link to a very simple exercise -

https://a360.co/3IVJY9q

I positioned the angled piece the way I want it constrained rigidly in all directions. I managed to constrain it in two directions alright. But the third is left unconstrained and if I try to constrain it using new constrain components feature it gives me this warning. Why? What can be more simple than constraining a part by aligning three pairs of flat surfaces?

The 30 X 30 Mounting Box has angled sides. Add an Align Component Constraint to the corresponding Origin Planes to finish off the placement. Model is attached. I had to ZIP the file to attach it.

I'm also having BIG problems identifying conflicting constraints, isn't there some way to get them identified so that you can adress the conflicts???!!!

Hi
I'm trying hard to add some diagonal ventilation slit cut-outs on 3 sides
of the Cover but am struggling to understand why I can't get this to work.
I'm not very experienced and have probably done some design mistakes along
the way. Any help is appreciated.

Hi,

If the two hexagons are not aligned in the same direction, there will be no flat surfaces in a loft.

The surface is not flat because sketches 3 and 5 are not fully defined.
1. In sketch 3, align the hexagon horizontally and dimension it.
2. In sketch 5, bind the center point to the origin.

Eureka! Thanks, I got it now. I hadn't thought about turning of the Body view to better see what you are doing and also kind of forgot about blue lines is a no-no. 🙄

I'll try to remember this learning experience. 🙏

Hi,

It is just as important, if not more important, that both hexagons are equally centered.
