I want to set hole1 = (1/3)*length. [note that "length" is the feature dimension, not a global variable]
So this absolutely can be done. There are several ways to achieve your goal, I will attempt to explain the what I believe to be the simplest way to achieve your purpose.
In the sketch of your feature that you want to control by equation, double click on the controlling dimension. (assumed from screen cap that you were using a hole wizard but other features also follow the same principle)
With the dimension selected clear the value, then type "=". Under the "Manager" tabs activate the feature tree, select the feature that has your driving value (your length).
Re-select the dimension box so the cursor is active, then select your driving value.
Then type equation.
What's your problem?
When you go to Value/Equation cel - click on Boss Extrude feature in Features Tree and now you can click extrude length dimension
You can do this by typing "=" then clicking the dim, divide by 3
I see you added a second image to the original post. So have you figured it out? What is it you're struggling with at this point?
yeah, I followed everyone's direction and it worked. Thanks
