Variables to show/hide features

Josy_La

Hi,

Can I use variables to show/hide a feature based on length of part? Typically my part has 2 holes at each end but sometime a 3rd center is required if the length exceeds 36 inches. I have modeled the center hole separately thinking it may help but I don't know how to approach it so that the part is adaptive.

Can anyone help?

Thanks Kevin it works perfectly.

You can put that length into a parametric variable (either with a manual variable feature or with the Measure Distance custom feature).

Then you can set the depth of your additional hole to something like

(#Length > 36 in) ? (1.5 in) : (0 in)

Parentheses optional. See the thread on Onshape expressions for this trick and more!
