Rotate part in Assembly

How come there is no indicator for how many degrees you've rotated a part? in rotate free mode..

Round objekts cant be rotated in grind snap mode perpendicular ro axis..

Someone got a solution? Am running inventor 2022...

Hello! Free Rotate does not have any angular control, it is completely free movement. If you want to control the angle, you will need to add some sort of angular constraint, and specify the angle off of some reference, such as an origin or work plane. For example, an angular constraint between a plane on the round object, and a plane passing through the axis of rotation.

There is no way to know where 45 is in the assembley. Basically what your saying is why make it easy when you can make it complicated.

A flat surface have the option of angular rotation by degree, but rot a round. Really inventor, really.?

So you have to make a plane that is in 45 in the assembly to constrain it to that angle.

Nope!

Attach your assembly here.

In some way yes there needs to be a constrain. There is no way to lock the angle before you mate.

Got **** this program is stupied. No function to offset by angel from mate.

How do i lock round objekts to a reference plane?

So mid section is turning around it's axis, i want them 45 degree separated from the one above.

That is a pretty picture - not an Inventor assembly files.

Can you just simply make a plane at an angle to any other plane/surface? I made this in the part environment but you could also make an Assembly-level plane to constrain against your other surfaces.

JDMather — Tue, 26 Oct 2021 16:23:46 GMT

Why would you need to create any planes?

Re: Rotate part in Assebley

filiph.sandberg — Wed, 27 Oct 2021 06:37:55 GMT

Yes it's possible to make planes in any angle. But what is the use?

I still haven't figured out how to constrain round/convex surfaces in the modell.

@filiph.sandberg every part has it own origin planes and axes and those can also be used in the assembly. If you click on the + in front of the part in the model browser and also do this for "Folded Model" and "Origin" the planes and axis will show (see image below).

By adding an angle constraint and using the origin planes of both parts you can constrain them 45 degrees from each other. Instead of using both origin planes from the parts you may also use the origin plane from the assembly.

Why would you want to move it by an exact amount? If it's not constrained that angle can easily change later on without you noticing.

Attach example assembly here. If your data is proprietary - simply make up a dummy set of files that illustrate the behavior and Attach here.

@filiph.sandberg

Here is one approach, but it all depends on your design intent.

First place an Insert constraint on the diameters that need to be mated together:

Then using one of the origin planes on each part, place an Angular Constraint, Directed Angle option (first of the three) and specify the angle that you want. That angle can then be easily changed later if you need it changed.

Your components will now be locked together, end to end, with the desired angle between them.

For example, an angular constraint between a plane on the round object, and a plane passing through the axis of rotation.

This is a very bad tool, almost like it was only developed halfway. Not all parts are cylindrical or simple cubes. We work with such weirdly shaped automotive components and its very difficult to predict your constraint beforehand, exactly why you need a incremented move to degree of rotation or move per grid x/y input. Perhaps the software developers should spend some time on Solid Edge and see how easy life can be. I really don't understand why simple tools have to be so difficult to use. You don't always know where you are heading with your design, and to plan accordingly is almost impossible.

Hi! I suspect you may like GripSnap better. It allows you to move or rotate a component with various means.

Many thanks!

I know it has some painful logic. Some simple operations are overly complex and time consuming. Can be really frustrating.
