Stacy Posted March 14, 2007 Share Posted March 14, 2007 I keep getting an error message Could not compute roof, house drawing too complex to compute roof. All I'm trying to do on the roof is change part of the roof to a gable end with a 100mm overhang. I can have one or the other it won't allow both options. Quote Link to comment
Guest Posted March 14, 2007 Share Posted March 14, 2007 Send the file to tech@nemetschek.net - you can even just send the roof without the rest of the file - along with a description of the problem and we will be able to take a look at the problem. Quote Link to comment
P Retondo Posted March 14, 2007 Share Posted March 14, 2007 Stacy, you can always convert the roof to a set of roof faces by ungrouping, and have more freedom to adjust the overhang. Quote Link to comment
Jonathan Pickup Posted March 14, 2007 Share Posted March 14, 2007 You might have parts of the roof that don?t make sense, i carry on editing the roof even though i get the error message that you get. Quote Link to comment
Amy L Posted March 15, 2007 Share Posted March 15, 2007 What qualifies a shape as too complicated? From day one I?ve been getting the same message as Stacy. Here?s a comparatively simple foundation outline that I attempted to convert by using the ?create roof?. (I can get the tool to work on simple geometrics.) After I select the polygon, fill in all the appropriate boxes, click, and get the evil message, I notice that a polygon is duplicated over my original. (no ridges, valleys, or overhangs) What?s up?

CipesDesign Posted March 15, 2007 Share Posted March 15, 2007 Each one of these (failures to compute) is somewhat unique. In your case I would guess that the rectangular inset along the bottom (just left of the 3 sided bay) is what's throwing the program for a loop. Often you can solve these issues by simplifying the original shape, then adding bits and pieces back on (either using the edit group command or, my usual choice, ungroup the roof into roof faces, then add faces as needed). Another thought/question: why is that inset "closed"? By doing this you have created a poly within a poly. Try removing the horizontal line that runs from the bay to the left and see what happens. Additionally, if you double click on the original poly you can check to see that each side has only 3 vertices (two corners & a mid-point). If there are extras these should be deleted (with the little "-" sign in the reshape tool) before running the command. HTH's Quote Link to comment
mike m oz Posted March 15, 2007 Share Posted March 15, 2007 Peter's right on the money. I pasted the image into a file and traced over the outline. Once you delete the indent the roof works. Having a quick look at it I think the reason it doesn't work as you have drawn it is because it actually can't work in real life (I might be wrong, but I don't think so). There is too much going on on the bottom side and the the valleys from the indent can't reconcile with the remainder of the geometry. You may need to think about the roof form again. AmyL if that is a simple roof I would hate to see one of your complex ones. Quote Link to comment
Stacy Posted March 15, 2007 Author Share Posted March 15, 2007 The roof that I'm trying to compute is simple. It allows me to create the roof but it doesn't allow me to edit certain areas of the roof. Quote Link to comment
mike m oz Posted March 15, 2007 Share Posted March 15, 2007 Stacy's problem was simple to fix. One edge was not horizontal by 20 mm (3/4"), This slight out of squareness was enough to make the Roof Tool not allow the conversion of all the hip ends into gables. (NB - VW 11 file) Quote Link to comment
Amy L Posted March 15, 2007 Share Posted March 15, 2007 Thanks guys?. I tried this once again with the original offender. (the inset was not originally selected, btw.) There *were* extraneous vertices that were eliminated. The new problem with this example is crashing after ?create roof? command on two computers, one with VW 12 and one with VW 12.5.1. So, thinking corruption I tried a new file with a whole different foundation and got results. (goofy roofline, but at least it worked.) The quality of the original polygon seems to matter. As far as complexity, shouldn?t any shape be ?roofable? (and then adjusted as needed)? The original example was just a portion of a ?real life? foundation. The garage was deleted out prior to this test, but the roof has been engineered and is under construction?.and this is a simple one. In real life the plate heights are all different, but being able to have a starting point from which to adjust things would be nice. Quote Link to comment
Vectorworks, Inc Employee Robert Anderson Posted March 15, 2007 Vectorworks, Inc Employee Share Posted March 15, 2007 Any time you get a "too complex" message, you should submit as a bugfile attachment to bugsubmit@nemetschek.net (This is how we eliminate all those "unique" failure conditions.)

Amy L Posted March 15, 2007 Share Posted March 15, 2007 Uh-oh, Robert. I can clog your in-box with ?unique? failure conditions. I can get this tool to work for me, but just for the simplest of perimeter shapes (see outhouse). Just kidding?.;-) I know I'm missing something. Quote Link to comment
AECCADPROcom Posted March 18, 2007 Share Posted March 18, 2007 i cannot add dormers. the documentation says i cannot use a plug-in object. but i seem to have no non-plug in objects in my rescource browser....why not?? the documentation doesn't explain fully - C:\Program Files\VectorWorks 12.0.0\VWHelp\wwhelp\wwhimpl\js\html\wwhelp.htm Quote Link to comment
Jonathan Pickup Posted March 18, 2007 Share Posted March 18, 2007 you can use a plug-in object to place a dormer, but you have to make it into a symbol first. Place one of your Resource Browser objects on the drawing, away from the roof. use the Object Info Palette to edit it to suit your situation. Then make it into a symbol, from the menu bar choose Modify > Create Symbol... now that it is a symbol, find it in your Resource Browser and place it on the roof. Quote Link to comment
AECCADPROcom Posted March 18, 2007 Share Posted March 18, 2007 thanks jonathan, sorry to be somewhat ignorant but now i can add the symbol to the roof however i still cannot get to the roof properities dialog with the dormers. I have already added roofing members, i don't seem to be able to select the roof only the framing members...any advice? many thanks, Dave Taylor Quote Link to comment
AECCADPROcom Posted March 18, 2007 Share Posted March 18, 2007 nevermind got it. thanks again for pointing me straight. Quote Link to comment
Guest Posted March 19, 2007 Share Posted March 19, 2007 Hi Dave Nice to see you here. How is the TC connection still - and your connection with Robert Berry ? And best of all the good luck to you and Jack new company. VW is great. Conrad Brink Quote Link to comment
AECCADPROcom Posted March 20, 2007 Share Posted March 20, 2007 Hi Conrad good to see you here and thanks! Things have been really busy but well for Jack and I. Rob remains loyal to TCAD and we stay in constant contact. Jack and I are not using TC at all and are loving Vectorworks as we continue to go thru the learning curve, really getting the hang of it now. Jack is focused on the drawing services and I am more on sales and training for Envisioneer and just starting to train and sell VectorWorks. We would like to do some training vidoes soon...so stay tuned. Quote Link to comment
Jonathan Pickup Posted March 20, 2007 Share Posted March 20, 2007 Dave, when you made the framing members they came to the front, so when you tried to put the dormer in the roof, you were snapping to the framing member. Send the framing menbers to the back then you should be able to add the dormer. Quote Link to comment
Daryl Wood Posted March 20, 2007 Share Posted March 20, 2007 Hey Dave and Jack, Good to see you two here, good luck with aeccadpro.com Quote Link to comment
