Using conditional expression in parameters

[tdesve]

Hi there.

I would like to calculate the depth of a drawer based on the hardware that can fit into the box containing the drawer.

The hardware comes in different sizes (250mm, 280mm, 300mm,...) and I need to use a conditional expression to 1st determine the hardware which can fit in the box and then calculate the depth of the drawer based on the hardware dimensions. In conventional language, I would use a "case of" or "if ... elsif... else" xpression to do so.

Can I emulate this in anyway within Fusion 360 ? I'm not sure we can create user defined function using the extension API in such a way they can be used in the Design environment.

In between, I will do it manually (which isn't a big deal either...).

Regards

Thierry

Hi,

For the arrangement of hinges in cabinets I used the workaround demonstrated in the screencast.

You can mimick some of conditional expressions using sign, min, max and other math tricks. See:

Thanks Günther, I got the idea ! That will work ! Thanks for taking the time to help me !

Thanks Vladimir ! Complements what Günther proposed. I will make it work that way ! Excellent !

Here is the final approach...

Each hardware has a nominal length (NL). Drawer will be smaller than that. And NL needs to fit in the box.

The approach works smoothly ! Thanks !

With that, I can automate drawer size calculation.

Have a good day,
