Christiaan Posted March 22, 2012 Share Posted March 22, 2012 Say I have a simple 3D model of a compost bin made up of extrudes, what's the simplest way to go about creating a schedule of materials from it? Quote Link to comment
Benson Shaw Posted March 23, 2012 Share Posted March 23, 2012 Here is a quick and dirty way. Assign each extrude a name in the data tab of its OIP (eg Front, LeftSide,RightSide, Bot, Top). Create new worksheet via RB. Database header column criteria to produce a cutting schedule: =N to list each extrude by name =Width =Length Or did you mean how to nest the extrudes on full sheets for most efficient cutting? -B Quote Link to comment

Or did you mean how to nest the extrudes on full sheets for most efficient cutting? Not even sure what you mean here. Got me interested though. Quote Link to comment
michaelk Posted March 23, 2012 Share Posted March 23, 2012 Christian This works for me: 1. Each type of stock gets its own class. 2. In a worksheet use the class as a criterion. 3. Get the volume of each extrude. 4. Divide by the area of the cross section to get length. This gives you a cut list. Add xx% and divide by the stock length to get a shop order. hth mk Quote Link to comment
Christiaan Posted March 23, 2012 Author Share Posted March 23, 2012 Thanks Michael, that sounds like the ticket. Quote Link to comment
Benson Shaw Posted March 23, 2012 Share Posted March 23, 2012 Not even sure what you mean here. Got me interested though. Nesting means arranging the rectangles on full sheets. Arrange them one way and you purchase too many sheets and/or end up with a bunch of little remainder pieces. Arrange/nest another way and you purchase fewer sheets, or at least have fewer, larger remainders. -B Quote Link to comment
Christiaan Posted March 25, 2012 Author Share Posted March 25, 2012 Ah I see, I'll be working with solid timber rather than sheets. Quote Link to comment
Christiaan Posted March 25, 2012 Author Share Posted March 25, 2012 This is a where a specialised cladding tool would come in handy. If VW understood what a cladding board/sheet it could just do a take off automatically without the user needing to deal with all this backend data stuff. Quote Link to comment
Christiaan Posted March 25, 2012 Author Share Posted March 25, 2012 Add xx% What's this step for Michael? Quote Link to comment
Tobias Posted March 25, 2012 Share Posted March 25, 2012 Added xx% would be waste factor. Quote Link to comment
Christiaan Posted March 25, 2012 Author Share Posted March 25, 2012 Gotcha, thanks. Quote Link to comment
michaelk Posted March 25, 2012 Share Posted March 25, 2012 Christian This is an example for a different application, but I think the basics are the same. The worksheet takes each stock (by class) and divides the volume by the area of the cross section to get the length. It has a place to enter the length of the stock. It checks the length of each piece against the stock. It adds the total lengths, divides that sum by the stock length, adds 10%, and rounds up to the next integer. The intent was to generate a quick cut list and shop order, but it should work for what you are trying to do. Excuse all the mathematical gymnastics necessary when handing dimensions in cubic, square, and linear feet and inches. This only works for square end cuts. (or end cuts that are mitered exactly the same direction and angle). mk Quote Link to comment
Christiaan Posted March 25, 2012 Author Share Posted March 25, 2012 Thanks Michael, much appreciated. I ended up doing it like this. It's a zip file so remove the .vwx suffix to unzip it. Help yourselves if anyone's interested in building a 3-bin timber compost bin. Quote Link to comment
