Counter top with/without sink family

[Chirag Mistry]

I have created this family. (see attached) whose intent is to have one 2-pick family where the user can specify with or without sink. The sink is embeded in as another family. I am able to control the visibility of the sink with a parameter, but not the void that cuts the opening...any thoughts on how to achieve this.

Thanks

Use yes/no parameters to drive the void. When the sink is "on" (checked Yes), use dimensions and formulas to move the void into a position to cut the couter top. When Sink is off (checked No) the void is pulled from intersecting the counter, and thus does not cut it.

My thoughts exactly Scott, but there are no visibility option under void property to tie it to a parameter.

You don't control the void visibility. You move the void parametrically to either cut or not cut the counter top depending if the sink is on or not.

I created a new parameter in your file, and a new Type called No Sink. I had to make your Sink yes.no parameter a Type parameter. You will now have at least two Type defined in your Family: With Sink, and No Sink. With Sink type turns the sink on, and lowers the void into the counter to cut it. No Sink type turns off the sink, and raises the void above the counter top where it doesn't cut.

Great just what I wanted.

Thanks a ton Scott.

Do you eevn need to show the opening modeled in the counter? I just leave the counter solid and use a symbolic sink that does the rest of the work.

I just used this technique to make a door with an optional raised panel at the bottom on each side. Clever! Thanks, Scott!
