panthony Posted August 27, 2006 Share Posted August 27, 2006 Here is how I find the valley lines in 2d using VW.... Please excuse the large images as I am trying to show detial lost with reduced image sizes. And here is an example of 5 complete roof hidden lines using the way stated above. Quote Link to comment
islandmon Posted August 28, 2006 Share Posted August 28, 2006 Here's a simple Worksheet describing the angular relationships based on a dual Gable roof design recently published in the 'wishlist' forum.. Quote Link to comment
LarryAZ Posted August 30, 2006 Share Posted August 30, 2006 With all the great solids modeling capability of this software it amazes me that we can't trim roof face 1 to roof face 2. Quote Link to comment
Abacus Posted September 4, 2006 Share Posted September 4, 2006 Anthony, The valley angle can be defined and drawn by the rise of roof 1 over the rise of roof 2. Per your first illustration the valley angle (ratio) is a 10/6. Example to form valley of 10/12 and 6/12 roof: Draw a line 10 units horizontally. From right end of that line, draw a second line 6 units vertical (up). Draw a third line connecting the ends of the first 2 lines (the hypotenuse). That is the left valley. Sorry for the long winded explanation. Actually much easier just double clicking on line tool and entering values for X and Y. Quote Link to comment
mike m oz Posted September 4, 2006 Share Posted September 4, 2006 (edited) Panthony, the roof object can do what you need very easily. All you need to do is create a roof object using the complete 'T' shape with a pitch of 39.806? and then modify the parameters of some elements: - Alter the slope of the individual roof faces forming the 'T' to 26.565?. - Change the Thickness parameter to Vertical Thickness so the different roof slopes match properly. - To get the eaves heights the same either adjust the eaves overhangs to the lower pitch roofs, or the pitching height, whichever is correct for your situation. This will give you the valley lines you are chasing in rendered views. If the 'T' slopes need to be rendered differently to the other roof slopes Ungroup the Roof Object to convert it to its individual Roof Faces.

panthony Posted September 4, 2006 Author Share Posted September 4, 2006 Mike, I realize that the roof tool will create the simple roof I used as an example. However the roof tool will not work on the complex roof samples I displayed. In the case of the complex roof layouts you need to work with simple roof objects to build most of the structure than you need to convert to hidden line and trace over with polys to make the planes. The roof tool needs some work to create complex structures and with that work I believe that NNA will add the trim plane features that we are all looking to see. Pete A Quote Link to comment
mike m oz Posted September 4, 2006 Share Posted September 4, 2006 Panthony - I agree that the Hidden Line rendering mode should generate surface intersection lines as well as edges. Hopefully it will come soon. Your roof examples are quite complex - way more so than anything I get involved with. I can't imagine you ever being able to do these with a Roof Object.

azizg Posted September 5, 2006 Share Posted September 5, 2006 if you make your big roofs using a combination of different roof objects, then once they are in the right location you can ungroup them to convert them into individual roof faces. Delete the roof faces you don't need, and double click on the remaining to change there shape so that they meet were there supposed to. Big pain in the neck but it should work. until some thing better comes along. Quote Link to comment
