I'm having problems with "Equation Curve" in Inventor 2025.1.

See the attached screenshot. After I enter the equation, I get the prompt "Select a dimension to reference the parameter". At this point none of the buttons are responding, including the check mark. If I select a dimension it puts the dimension reference, in this case 'd0' at the end of the equation and the equation turns red!

This was not the behavior for Inventor 2024!

Hi! I guess the template unit is inch not mm. Please try using an mm template. Or go to Tools -> App Options -> File -> Configure Default Templates -> select the desirable standard and unit.

Many thanks!

Still doesn't work. Same problems. The same equation curve works in Inventor 2024 with no problems, even before I modified the template today.

Hi! Please share the file here. I tried entering the same equation and it worked for me on 2025.0.1.

Many thanks!
