Ryan Seybert Posted May 17, 2021 Share Posted May 17, 2021 Not sure if I've missed a checkbox somewhere or if the software is just disconnected from reality. 36" lighting pipe out-hung off the top of 12" truss. Changing the connection type between "fixed" and "Pliable" makes no difference. Help? Quote Link to comment
Vectorworks, Inc Employee jcogdell Posted May 18, 2021 Vectorworks, Inc Employee Share Posted May 18, 2021 The most likely cause for this from your image is that the pipe has lost its connection to the truss and truss cross (blue diamond). If the problem is not visible in a 3D view, the easiest way to check if this has happened is to hit the 'Change trim height of system' button in the Truss properties and once in the Change Trim Height dialogue set the 'Change' drop-down menu to either stacked or entire system. This will highlight everything that is connected to the truss system, not just the objects directly associated with the truss line itself (which is displayed by the select system objects button). If this is not the case PM me the file and I will see if I can figure out what is going on Quote Link to comment
Mike Wright Posted September 21, 2021 Share Posted September 21, 2021 Hi I'm coming across the same problem here. If I use the insert connection tool to add a pipe, it draws the pipe and connection at a different height (in the picture below the truss Z value is 0mm, it has inserted the pipe at a Z of 1835mm When you change the trim height, the connection symbol adjust to the new height but the pipe just moves up by the amount entered. See below: After the trim height is adjusted: Quote Link to comment
Vectorworks, Inc Employee jcogdell Posted September 21, 2021 Vectorworks, Inc Employee Share Posted September 21, 2021 Check that you don't have enable vertical offset toggled on in the insert connection tool mode bar (its the green tick icon to the right of the tool preferences) Quote Link to comment
Mike Wright Posted September 21, 2021 Share Posted September 21, 2021 That's sorted it thanks. It's not an option I've ever used though so perhaps it is default on by mistake? Quote Link to comment
J. Miller Posted September 21, 2021 Share Posted September 21, 2021 same problem here. The light pipes w/ out rigged fixtures are connect to the truss. I can change the elevation of the entire system. but i get all kind of errors when running calculations in braceworks. Can anyone tell me what is going wrong? VW2021 Thanks Jeff Quote Link to comment
J. Miller Posted September 21, 2021 Share Posted September 21, 2021 juat to follow up it seems connections must be type rigid . If an outrigger pipe is used i can not attach a fixture to that truss system without getting the warning of "point load assigned to (2) elements) it seem the calculations are working anyway with that warning is this a glitch?? Jeff again Quote Link to comment
Vectorworks, Inc Employee jcogdell Posted September 22, 2021 Vectorworks, Inc Employee Share Posted September 22, 2021 @JMiller 11 hours ago, J. Miller said: it seems connections must be type rigid that is the designed behavior, a flexible/pliable truss cross is designed to represent fixing the pipe with a steel rope or some other form of non rigid (movable) attachment method (which in the case of an out-rig pipe would be dangerous), where as the fixed definition is to model a rigid or hard connection like when using doughty clamps or burgers. 11 hours ago, J. Miller said: If an outrigger pipe is used i can not attach a fixture to that truss system without getting the warning of "point load assigned to (2) elements) I not 100% sure whether this is bug, as I can kind of see why it might get triggered. I'll contact the developer and ask about it. 11 hours ago, J. Miller said: It seem the calculations are working anyway with that warning Not all warning/error messages will prevent a truss system from calculating, typically as long as the issue will not physically prevent the calculation then Braceworks will calculate the system. The issue highlighted may for example just refer to a potential documentation problem like having several hoists with the same ID. Quote Link to comment
