Adaptive greyed out scissor spring

SanJose319 — Mon, 28 Jul 2025 08:08:25 GMT

In the image shown, I want to make scissor spring component as adaptive. The component's adaptive feature is greyed out (disabled). The component is not grounded. How can you enable the adaptive feature of the part?

Thank you.

Jerome

Hi!

Edit the spring and turn the sketch adaptative.

A component's adaptability stems primarily from its creation (the process of making its geometry dependent on other components), not from assigning a status.

How was this spring created?

If it is to be adaptive as a component, the sketch that defines its geometry and makes it dependent (logically and constrainedly) on the other component must be adaptive.

Hello @SanJose319 ,

if the spring is adaptively in any other assembly, you cannot set it adaptive in a second assembly.

Open the spring, go to Document Settings - Modeling - Adaptively Used in Assembly. Switch off this option and try setting the spring adaptively in your assembly.

I believe if you follow along in the tutorial that those scissors came with then it should explain it.

Hi! A few possibilities. The part is already adaptive in another assembly. To steal adaptivity, you may open the part (or edit the part in place) -> Tools -> Doc Settings -> Modeling -> uncheck "Adaptively used in assembly." However, once you make the change, the adaptivity of the given part will be disabled in the other assembly. You cannot have an adaptive part stay adaptive in two different assemblies.

The adaptive part has non-Primary Model States. Once it has non-Primary Model States, the adaptivity is disabled, since non-Primary Model States do not support adaptivity (or vice versa).

Lastly, it is also Model States related. When the hosting assembly has non-Primary Model States, the adaptive part can only be adaptive within one Model State.

I believe one of the above should explain the situation. Please feel free to share the files. I can help take a closer look to understand the behavior better.

Many thanks!

Thank you Johnson

This setting works.

Now moving to another problem about Drive parameter. Please advise about the message below.

Thank you.

Just share here the files... without them we can guess what's wrong, since there are a lot of things going on in a model like this.

They are already on your computer, check:

(the xxxx is whatever version of Inventor you are on)

SanJose319, you appear to have made a new assembly, have you remade any of the parts?

If you do post your files someone may be able to figure out if there is anything that you had done differently that's causing any of the problems.

For the initial question the reason Adaptivity was greyed out in your Assembly1 was that the scissor_spring-1.ipt was already adaptive in the scissors1.iam assembly.

As for the Drive constraint problem, I only get that error when I'm in an assembly where the spring is not adaptive - in the scissors1.iam it works fine, and if I create a new assembly and copy over the parts with their constraints, then clear the adaptivity in the old assembly and make it adaptive in the new assembly then it drives okay, but I get that exact same error if I try to drive the constraint in the assembly where it is not adaptive.

Please post your files so we can determine what you might have introduced into this otherwise working assembly that is suddenly creating these problems. Thank you.

Hi! I don't know what was changed with the sample/tutorial file. Please share the files here. I would like to understand the adaptive behavior better.

Many thanks!

Hello @johnsonshiue ,

I am sorry for the late response as I was offsite.

Here's the assembly (zipped) file.

Thank you for your patience.

Hi! Many thanks for getting back to me! You did not do anything wrong. Please refrain from apologizing!

I took a quick look at the files. I see why Drive Constrain fails. Although the scissor_spring:1 part is adaptive, the feature isn't adaptive. Simply edit the part in place and right-click on the Extrusion -> check Adaptive. Return to the top. Try Drive Constraint again. It should work.

Thanks again!

Hello Johnson,

Thank you for the help. That worked! attached is the drive animation.
