Unable to add a user parameter

[aleshep]

When I'm trying to add a new user parameter I get red highlighted field 'Name' and disabled 'OK' button. What am I doing wrong? Thank you.

Hi,

If there is already a name with tolerance first, it might not be allowed.

Hi Günther. Thank you for the answer. But there is no parameter named 'tolerance'. At least I cannot find it in the list. Where it can be defined?

[HughesTooling]

Have you copied and pasted any components into the design from another design or inserted and then broken the link? If you have did they have a parameter named tolerance that you renamed? The other place to look is have you renamed any of the model parameters?

Hi Mark. Thank you for your answer. I've checked all items from 'Name' column. There is no parameter named 'tolerance' 😞 I don't remember whether I copied models from other sources, but I think I didn't.

[HughesTooling]

Just to confirm, it is just adding a new parameter named tolerance that's the problem, you can add a parameter with a different name OK?

[aleshep]

Yes there is no problem with other names.

The only time I've seen this was when I copied a component from another design. What I saw was when pasted in I got a parameter with _1 appended to it. So in your case tolerance_1 but what was odd was there was also an invisible parameter created called tolerance. There was no way to edit or delete this parameter but I think I could reference it in another parameter's Expression. If you create a new parameter and name it TEST then in the value enter tolerance do you get a value?

Are you able to share the design here as an f3d or with someone from support? Maybe @jeff_strater  could look at it.

yeah, I've been lurking on this one, and am curious.  If you want to PM me a link to the design, @aleshep , I could look at it, and keep it confidential.  @HughesTooling - the only thing that I thought of is that in CAM, isn't "tolerance" a special value that you can use in dialogs?  Not sure if that is a true parameter or not, but could that keyword have somehow leaked over into the design side?

[HughesTooling · Accepted solution]

There is a tolerance variable in the CAM workspace but never come across parameters\variables from CAM being seen in the design workspace.

Here's an example of what I described above. Copy\Paste New into another design and tolerance becomes a hidden parameter. It you delete the component and tolerance_1 parameter the hidden parameter is still in the design. You could also lose track if you renamed the tolerance_1 parameter.

I've attached the design.

Thank you Mark very much for your time! It's rally very helpful for me. And the last question: if is it possible to find and remove that hidden parameter. Thank you.

[aleshep]

Hi Jeff. Thank you for your answer! It seems Mark found the reason of this issue. If it is still necessary, I can send you my design.

[jeff_strater]

great!  Glad to hear that Mark was able to track it down.  No need for us to see the design.  Thanks!

No, as far as I know it becomes invisible and uneditable. Your only option is use another name, but you'll need to be careful not to type tolerance by mistake while doing the rest of the design.
