Truss Cross: what why, how to get rid of?


Recommended Posts

What is this crap and how do I get rid of it?

See attached pic and file

I tried using an existing symbol in my library and a newly imported symbol from Tomcat.

I placed the corner block using the insert truss tool from a front view to stack it on top of a 10 vertical piece these data tags became visible.

When selected they show up in OIP as a Truss Cross.

There's no class associated with them.

So I deleted them, only to have them come back when I nudged the whole truss piece

WTF is this crap?

A new "tool" that I didn't ask for?

Why Why Why Vectorworks do you make my life so miserable?

Anyone know how to get rid of them?

Thanks

OK this is weird and should not be happening. Just taking a look.

 

They denote a connection between 2 separate rigging items and have data fields so force data can be populated after a braceworks calculation. 

 

However, your truss should be able to just connect, so I am just doing a bit more digging now...

OK I think I have fixed it. The truss symbol data was missing Bottom 3d (Screenshot Attached). This was causing the truss to connect using the insert connection mode (as if you were doughty clip the two truss pieces together). By validating this field (that side? or face?) of the truss object will now connect using the preferred truss connections and will no longer create the connection crosses on your drawing.

Thanks Tom,

That's something that needs to be fixed in the Tomcat library.

This must be some new feature because I've never seen this before.

Did you just check the unchecked box, and fill in the XYZ based on the top?

I'd like to know in case I see this again

It looks like the issue is not with the truss corner as the corner is setup properly.  That particular corner has no Bottom 3D connection as it is a 5-way corner and the geometry reflects that as there are no gussets on the bottom.

 

This may be a bug in the truss code and not the content.

@JustinVH You bring up an interesting point.

In a 5 way corner what is "top"

This might explain some of the cussing I was doing at VW while trying to build a simple 4 post truss box around a stage.

Using the insert truss tool I had placed a 10' stick as a leg vertically, and when trying to insert the corner block it kept putting it on the bottom of the leg and not the top.

I had to manually move it, then it all of the various pieces I attached using the insert truss tool where sideways not top and bottom.

A simple 30'x30' box with 4 legs should have taken 30 seconds to a minute to build using the insert truss tool, and instead it took me a half hour part of which was fighting the anomaly we see here.

It seems the VW truss tools have gotten more complicated than useful.

How would I set a 5 way corner so the open end is on top, or on the side if the corner was part of a larger system?

In a 5 way corner the open end of the corner is considered the top so this particular symbol is upside down so that will be corrected for the next version.  It is an older symbol and was missed when the standards were changed a couple of versions ago.

 

When I build truss structures that beed to be built vertically I always do so from an isometric view so that I can pick whether I want to build up or down as the default direction is down when building in Top/Plan view.

 

In order to have a 5 way corner with the open to the side you have to manually rotate the corner once placed or make a duplicate symbol and adjust the 3D geometry so that the open end is on the side that is preferred.  I was able to manually rotate the corner using the rotate tool to get the open portion to different directions.  It appears that when the hanging angle of 90° is used to insert a vertical truss the corner connections get rotated oddly.  This is what was causing the open end to be in an odd location.  I found that if I insert the first vertical leg on the ground from a Top view and connect the corner I can then switch to a front view and use the rotate tool to rotate the whole structure vertical.  From there I can connect the remainder of the truss to complete the rig.

 

I have also attached two corners for you, one with the opening at the top which is correct and the other with the opening to the right.  When you place the corner with the right opening onto a piece of truss on the ground and rotate to vertical the opening will be at the top.
