I have a simple "Block" object. It represents 2x6 PT decking. I need to find the surface area of the object in the master script....Parameter A x Parameter B......then divide by the surface area of a 2x6x16' (7.33 sq. ft.) to find the number of 16' pieces required. <BR /> <BR /> I seem to recall that there is a certain function you have to perform on the A and B parameters in order to change them from feet and inches to something that you can multiply. <BR /> <BR /> I feel ridiculous asking this because it seems like it should be so simple. Any help would be appreciated. <BR /> <BR /> Doug</T></DIV> Tue, 17 Dec 2013 02:11:17 GMT https://community.graphisoft.com/t5/Libraries-objects/Multiply-quot-A-quot-times-quot-B-quot/m-p/114663#M12851 Anonymous 2013-12-17T02:11:17Z https://community.graphisoft.com/t5/Libraries-objects/Multiply-quot-A-quot-times-quot-B-quot/m-p/114664#M12852 Internal units are meters.
