Help on API command to have outputs reflect updates made to the command inputs using parameters

[2way3dtext]

This command creates a pipe along a selected path and a sphere at both ends.

Is there a way to modify the code so that when a set value for the pipe diameter is changed, the diameter of the pipe body (and spheres) also changes automatically?

I tried using a parameter to change command inputs. I first created a parameter value and set it equal to 5mm. Then, the parametric value was set as a diameter input for the command. After selecting a path, the command created a pipe with a diameter of 5mm. However, the diameter of the created pipe remained 5mm even after the parameter value was changed to 10mm.

May I receive some feedback on a possible solution to this problem?

Hi @2way3dtext .

We need to associate the user parameters with the sketch dimensions.

https://help.autodesk.com/view/fusion360/ENU/?guid=GUID-716cfabe-74ff-435e-a3e2-45dc203b8719 

I've modified various parts of the code to make the association look like this.

linearDimension.parameter.expression = pipeDiameterIpt.expression

For detailed changes, please compare the attached file with the one you created yourself.

Also, on a different note, if I do the following in the ExecutePreviewHandler, the Execute event will not be fired.

eventArgs.isValidResult = True

This is commented because it is useless.

Thank you so much for inspecting and revising my code.

I searched through the fusion 360 homepage for a solution, but I was unable to find any leads before your reply.

Thank you again for your generous time and help.
