wkwiat Posted April 21, 2019 Share Posted April 21, 2019 (edited) Hi All, Looking for some help and direction. I am trying to estimate the weight of a truss grid with decking. Its a 36' (L) x 12' (W) x 12' (H) grid out of Tyler 12" truss. I am stuck at the first layer with the truss connections. I keep getting a warning "Cross section types do not match". I read a few posts about corner blocks and I have tried to use the correct corner blocks for the drawing and not what I am using in actuality, ie 5-way verses 3-way. I have attached a screen shot of where i am at currently.... Edited April 21, 2019 by wkwiat Quote Link to comment
SCParker Posted April 21, 2019 Share Posted April 21, 2019 I’m not at my computer at the moment but it will be helpful if you could post the file. Short of that, post a screenshot of each of the configuration windows for the braceworks objects. 1 Quote Link to comment
wkwiat Posted April 21, 2019 Author Share Posted April 21, 2019 Thanks for the reply Scott! Any help would be much welcomed. I uploaded a stripped file of the truss structure I am trying to calculate. Let me know if you need any further information about the structure and thanks again for your time!

SCParker Posted April 22, 2019 Share Posted April 22, 2019 wkwiat, I think the two types of truss you're working with are different. As in, one is the "AV" line and the other is the "Bolt" line. The corners seem to work with the AV line of truss. The workaround is an 11 step process that I've been able to figure out and you'll need to do it three times. One each for each truss object. You'll basically be resetting the cross section to 12" for each item and it should work after that. It might be easier to change the truss types in future. I hope this helps. Note that my workaround is likely not the "correct" way of dealing with this, but it worked. 🙂 Also note that this likely changes what an engineer would need if one is needed. If you want to calculate weight, you'll to add hoists. I know it's ground supported, but Braceworks doesn't understand ground support. Best, Scott Quote Link to comment
wkwiat Posted April 22, 2019 Author Share Posted April 22, 2019 I did notice in the object info window for each item that the cross section type was different but that they were both "connectable" with each others type. They are all Tyler truss elements. When you say "It might be easier to change the truss types in future." you mean change the manufacture? It is for reference anyway. It is ultimately ground support but we are intending to use hoists to lift for the build. I was making sure the truss was working before adding hoists. I have struggled with braceworks at times and learned to take it in parts. I also have to "attach" decks to the structure. In real life they will be secured with hardware and straps, but how would get that weight represented correctly? Would the best thing be to add a distributed weight load to the structure? Thanks for your time Scott and anyone reading! Wayne Quote Link to comment
wkwiat Posted April 22, 2019 Author Share Posted April 22, 2019 Another thing I have been trying and failing is using grapples? Quote Link to comment

This is one that you'll fair better by inserting corner blocks for most of your work and then change out for grapples after your calculation needs are done. Straight truss currently do not have a way of having this attached off to the side. Or, placing the side truss under/over the main truss line to make that connection point. 1 Quote Link to comment
Vectorworks, Inc Employee JustinVH Posted April 22, 2019 Vectorworks, Inc Employee Share Posted April 22, 2019 Keep in mind that the Tyler Truss symbols do not have cross section data and are missing some of the weights. We have tried to get the necessary data from them but have been told they are not willing to release it to us at this time. 1 Quote Link to comment
wkwiat Posted April 22, 2019 Author Share Posted April 22, 2019 Thanks for the response Justin. I did notice the missing weights of the corner blocks and added that in manually. I know the database is expanding and information sharing, in our industry, moves slower than most. Quote Link to comment

We are trying to make our industry safer and work easier and a major manufacturer is unwilling to work with others. Yeah I'm trying to find out the weight of a Tyler Truss 12x18x96" stick and that's frustrating. Quote Link to comment
Vectorworks, Inc Employee JustinVH Posted April 24, 2019 Vectorworks, Inc Employee Share Posted April 24, 2019 I would recommend to contact them and voice your frustration. Sometimes the "squeaky wheel gets the grease" approach can help to show a manufacturer that they need to be more forthright with their data or risk losing customers to other manufacturers that are sharing weights and structural data.
