properties expression in schedule

Dave Seabury — Thu, 03 Oct 2024 15:46:40 GMT

Trying to get the height of the rough opening into a schedule. I have a property with the following expression, W/D Nominal Sill Height - .375in. The schedule will give the correct height of the sill but will not subtract the .375 for the rough opening. What am i missing?

Thanks for any insights

So if you select any window, open the property settings and press the 'Evaluate' button, do you get the correct answer?

If not, then there is something wrong with the expression.

Maybe show a screen shot here.

If that is all good, are you adding that property as a field in your schedule settings and not just using the sill height?

Evaluate does not return the correct value. it only shows

feet and inches (4'-2") no fraction, it should be 4.'-2 1/8".

the schedule shows 4'-2 1/2" which is the value of

W/D Nominal Sill Height.

I'm thinking that i have to somehow qualify the Value of

W/D Nominal Sill Height as an expression using feet and

fractional inches not just feet and inches.

I am not sure about expressions when it comes to Imperial units.

I know with metric we can convert to the unit we want.

Maybe also the Working Units or Calculation Units in the Project Preferences will have an effect?

Calculation units was set to 1", changed to 1/16" and

all is as it should be. Thanks yet again for your help
