Wesley Burrows Posted November 9, 2017 Share Posted November 9, 2017 (edited) For manufacturers that wouldn't (or just haven't) provided the truss cross-section information to be included in the Vectorworks truss library. (Ugh) What is the right information to ask for from them, on an individual request basis? I think I remember it primarily being the lxx, lyy, and lzz. But I can't remember the exact terminology. Or should I just send the screen shot and ask them to be so kind as to provide the asked info? Edited to add: Tomcat responded to me and they aren't providing that information at this time, but their engineers have a meeting with Vectorworks after LDI. Fingers crossed :-) Edited November 9, 2017 by Wesley Burrows Quote Link to comment
Wesley Burrows Posted November 9, 2017 Author Share Posted November 9, 2017 1 minute ago, Rob Books said: we request from them, Moments of Inertia, Bending Moments, Shearing Force, and Tube Force. and Yes, hopefully we will Get Tomcat and J. Thomas onboard after the meetings at LDI. for some that are missing Data, the Manufacturer is working with us, just taking them time to get the data to us and then converted to the cross-section in Vectorworks. the nice thing is that I was able to set most of them up with an ID so that once the Cross Section is in, it will auto correct and we won't have to re-issue libraries. For those those of us that also have some quantities of slightly less mainstream manufacturers. (Applied Electronics in my case) Where they aren't in the library at all, what would be the appropriate method to try and obtain that info? Quote Link to comment
CETLV Posted December 11, 2017 Share Posted December 11, 2017 Has there been any updates on this? I am still searching for accurate cross section info. on a multitude of manufacturers. Quote Link to comment
CETLV Posted December 11, 2017 Share Posted December 11, 2017 (edited) Well, its hard to say. I design for different manufacturers all the time depending on who the house rents from. One of the most common ones I have seen lately is XSF. Its just sort of a bummer that braceworks is essentially useless with its math unless you get very specific data. I am also curious about the chain cross sections in the hoists. rigid seems like itll work just fine, however not all chain has the same details. but i mean if a chain fails before other components, you failed math in first grade. I am indeed a SS guy, so I will keep a lookout. Edited December 11, 2017 by CETLV Quote Link to comment
Wesley Burrows Posted December 13, 2017 Author Share Posted December 13, 2017 (edited) Seems pretty short-sighted on Tomcat and J Thomas' part. Seems akin to some curmudgeons in a boardroom circa-1995 harping on about how the internet is a fad. Edited December 13, 2017 by Wesley Burrows Quote Link to comment
CETLV Posted December 14, 2017 Share Posted December 14, 2017 Perhaps they believe that people are going to rely on the software and despite any "disclaimer" they are not going to get out the calculator and do the actual math! Quote Link to comment

And to further that, I might assume that any company forwarding that information, regardless of it’s accuracy, is opening itself to liability concerns from a legal standpoint. Quote Link to comment

If they use the heavy duty numbers, and get the OK in Braceworks, then actually rig light duty and it fails, then thats what they are likely thinking. However someone who is serious enough about rigging knowledge to pay 5 grand for a license you would hope wouldnt be so negligent... Quote Link to comment

I mean, CM motors have a liability disclaimer on them about not for use for lifting loads above peoples heads. ¯\_(ツ)_/¯ Quote Link to comment
Enoch Seutter Posted March 9, 2018 Share Posted March 9, 2018 Speaking of Christie Lites coming on board, I have noticed the link bars on B-Type 16" truss don't work properly when connecting them. It only acts as a short extension and doesn't change the angle of the truss connection. Picture attached : Top is what BW and Insert Truss Tool does, bottom is what it should actually do. At this point the link bars appear to be useless. Enoch Quote Link to comment
SCParker Posted March 10, 2018 Share Posted March 10, 2018 Enoch, Timing is everything. I have been playing with the link bars as well. I made a tiny L-corner that matches the 7.5° link bar. I've not had time to make the rest. File is attached. LinkBar.vwx Quote Link to comment
Enoch Seutter Posted March 12, 2018 Share Posted March 12, 2018 Awesome thanks Scott! I have been messing around with the 22.5 degree link bar myself. When making a full circle I can't get it to match up 100%, eventually I will get the L1/L2/L3 just right that it will work. Quote Link to comment
CETLV Posted March 12, 2018 Share Posted March 12, 2018 just as long as you guys realize that these custom bars that are being made are NOT accurate in the braceworks calculations. unless you have the exact cross section data you cannot reliably use anything generated from braceworks.

Enoch, I discovered that changing the drawing units to Microns was very helpful. Change back after you've built the L corner. Quote Link to comment
Projx_CA Posted March 12, 2018 Share Posted March 12, 2018 Are the Christie Lites truss symbols supposed to have Cross Section data? They appear to be set as RIGID Quote Link to comment
SCParker Posted March 12, 2018 Share Posted March 12, 2018 Same here. I meant to comment that the link bars missing that info didn't really matter since they're all set to rigid. Quote Link to comment
Projx_CA Posted March 23, 2018 Share Posted March 23, 2018 On 3/13/2018 at 6:18 AM, Rob Books said: The way that Braceworks gets the data for the cross sections is it reads a file in Vectorworks. All truss that has been released, including the Tomcat/Thomas, once we have the data and put it into the program, and that service pack update is released, will then populate with the non-rigid data automatically. Rob, Does the cross section file need to be updated separately, or is it part of the service pack? The Christie truss still registers as rigid, even after the SP3 update. Thanks!

SCParker Posted March 27, 2018 Share Posted March 27, 2018 Hey Rob, Is there any way for Braceworks subscribers to obtain the needed info without having to wait for service pack releases? Wouldn't it be possible to either open a file that contained updated truss objects? Or, simply enter the numbers into the cross section info box? Thanks, Scott 1 Quote Link to comment
SCParker Posted April 1, 2018 Share Posted April 1, 2018 Hi Rob, Understood. If you have the info for truss, is there a way to obtain the update without having to wait for the next service pack? Quote Link to comment
wadecordts Posted March 11, 2019 Share Posted March 11, 2019 I got a reply from my email to XSF. They said that they have been working on putting together models for Vectorworks for over a year, and that they sent over the models to Vectorworks about a month ago. They said they are just waiting on Vectorworks at this point. On another note, It seems like there is only 12" truss for XSF in the library. Why is the 20.5" truss not available?
