Parameters for Listing

Dave Seabury — Wed, 21 Dec 2011 18:40:35 GMT

Is there any way to schedule roof pitch? I have a parameter 'pitch' where you enter the value for 'x'...........x/12. I am trying to schedule the value x/12.

pitch = 8
PARAMETERS pitch_for_listing = pitch/12 ....results in .667
PARAMETERS pitch_for_listing = '/12' .........results in /12

Is there any way to get the value of 'pitch' in front of /12? 8/12

Thanks in Advance

Dave:

You need to combine the numerical value with the text, so your code should be something like:
PARAMETERS pitch_for_listing = pitch + "/12"

I'm getting a "incompatible type expressions" error. The value for the pitch has to be a dimension or a real number and the pitch_for_listing is a text value, so i think this is where the error is coming from. I tried looking through the GDL help file to see if i could convert the pitch value to text but didn't come up with anything. Do you know if this can be done?

Thanks for your input

Hello,

Make the pitch_for_listing as a string type parameter.
Then you could use for example;

pitch_for_listing= str(pitch,1,0) + '/12'
parameters pitch_for_listing= pitch_for_listing

Hope this works / helps.
