Side arms

Recommended Posts

So I'm modeling some basic booms from my theater. Because I have time on my hands, and can be nitpicky, I'd like to have the lights in the drawing on side arms like they are in real life. Using the Safer Sidearm from the resource manager, when I insert it, it either ends up in space about 20' from the light or it puts the c-clamp end in the middle of the light where the shutters are. I don't understand how this is supposed to work.

You linked me to a very informative webinar that didn't answer my question. In the webinar he builds booms with full 2" pipes rigged 90 degrees off of a vertical pipe that he converts to hanging positions and hangs lights off of. The sidearms I am dealing with are of the 1/4" pipe rigged to a light in the place of a traditional c-clamp which has a c-clamp on the end of the pipe which is then hung on a vertical pipe. In the resource manager library there is a symbol under lighting accessories that is just the type of sidearm that I'm talking about. It is the City Theatrical Safer Sidearm. It being a light accessory, I would think that I would be able to attach it to a lighting instrument in the correct fashion coming off the top of the yoke horizontally 90 degrees. Instead it attaches to the light in the center of the fixture and doesn't perform the way that I would want it to at all. Now all this being said, in the 5 days since I initially asked this question I have modeled my own sidearm that is more realistic looking to my purposes and gotten it to behave the way I wanted. But thank you for trying to help.

Having replicated this issue myself just now, @TomWhiteLight I wonder if you or someone could share what the proper method is for using this symbol as a static accessory. I assume I'm using it improperly or have an incorrect setting engaged somewhere. Or maybe the Safer Sidearm just isn't designed to be used as a Lighting Accessory but instead only as a hybrid symbol with the Symbol Insertion Tool.

 

In my workflow I have previously always used my own hybrid symbols to represent the different kinds of Sidearms, and haven't actually inserted them as lighting accessories to date. Clearly this symbol is supposed to be inserted as a lighting accessory, but isn't functioning properly in my tests, so I'm curious as to what I am stuck on.

 

Like @AWaters said, when I try and associate this static accessory [Light Acc City Theatrical Safer Sidearm] with a lighting device, it seems to place it somewhere in the middle of the Z height of the 3D portion of the lighting device, or below the 3D geometry of the lighting device, like in the screenshot below.

This differs greatly from how I had placed it in Top/Plan (see below). I'm left wondering why the 3D orientation (rotation and +Z height) were completely changed when it became associated with the lighting device, and how we are supposed to use it when hanging a light from a vertical position. Here is how I inserted it:

1716005505_ScreenShot2020-08-17at11_59_12PM.thumb.png.174feec90b48c1aff6653e3ac24d9c6b.png

 

Again, the thought being that by inserting a Hybrid symbol from the default libraries, I am interested in using the 3D portion of the symbol to communicate how it is hung in real life - off of a vertical position or "boom". The sidearm's 1/2" (or so) Pipe would be at the height of the fixture yoke where the C-Clamp is drawn attached in 3D, and the rotation would be taken from what I drew in Top/Plan.

 

Instead what seems to be happening is that the symbol is following the behavior of any scroller lighting device accessory. It seems to have a +Z height of +0" starting at the "front" of the fixture, aka the gel frame slot. Mind you, this is the expected behavior for a scroller accessory, since they are mounted to the front of a fixture. However, it doesn't carry over to this type of accessory. Adding any +Z to the sidearm, +18" for example, causes the accessory to be moved "down", further away from the front of the fixture. So, further away from the yoke's mounting point. I cannot put in a negative value into the Z field for an associated lighting device accessory, which I'm assuming is purposeful and has to do with the relationship to the "parent" lighting device.

 

Like I said, my personal workflow has been using homemade symbols for various "Iron" in the past (sidearm, c-clamps, cheeseboroughs, etc). Curious to see how the provided Safer Sidearm symbol is designed to work as an accessory so that I may incorporate that in the future. I'd rather not be stuck in the 2008 way of doing things if there is a more efficient way!

 

Thanks in advance!

I think I understand, Just CC'ing my colleagues as this will have implications for future versions

 

So in the real world the safer sidearm replaces the C clamp and attaches directly to the yoke. They are rare over here in the UK I didn't notice them in the library before.

 

You could make these static accessories but you are going to need fine control of the orientation of the side arm. Rotating accessories is a few more clicks than rotating hanging positions. I think its misleading from us to have these in the accessory folder, I understand why they were put there but I think we need a different folder called 'rigging hardware' or similar.

 

I understand that they are permanently attached to the yoke, but they will need to be easily re-orientable and the lighting instrument will need to slide along the arm much like a lighting pipe. I know that an accessory will rotate with an instrument but we need the C-Clamp part of the side arm to remain a fixed point that the lighting device pivots round.

 

I think moving forwards they really should be a rigging object.  I don't think these objects will meet the criteria for accessories in the future.

 

Workaround

 

I would make the side arms hanging positions (you could make them rigging objects but HP would be easier for now) and use right click attach to rigging object.

 

Select all of the side arms on a position and use Spotlight Numbering to assign names of positions...

 

For my Stage Right 1st side position I make the prefix SR1/ Then I number incrementally from bottom to top so I am left with the following names

 

SR1/1

SR1/2

SR1/3

SR1/4

 

I would also duplicate the leko symbol you are using and make a version without the C-Clamp, you could even make a version that had the small clamp that the safer sidearm uses. Do not delete or remove any Loci during this process.

 

If you need to create a report of which units have the side arms, I would use a custom field in the OIP which can be created through Spotlight preferences. If you need to send this information to Lightwright I would repurpose one of the user fields for this, perhaps rename it rigging or hardware.

 

Reach out to me if you need help with customising data fields.

So last week when I realized that I wasn't going to get a fast answer I made this model. This is a decent approximation of what a standard sidearm looks like here in the US. The Safer Sidearm is a modified version of this that puts more strength at the clamp on the pipe, but I've never actually seen them in real life. I started with a c-clamp that I found in the Resource Manager, extruded a 1/2" diameter circle off the center of the clamp, and then modeled that little tee piece that connects to the light. I converted this all to a symbol. When I brought the symbol into my drawing I converted it to a static lighting accessory, and then attached that to the rigging position that is my boom. I then did what you suggested and made a new version of the light I intended to hang and removed the clamp from that symbol. Then I went lazy and just lined up the top center of the yoke with the tee on the sidearm in 3D. Then I attached the light to the rigging position that is the boom as well. So now I can move the boom anywhere in my drawing and everything moves together. The light and the sidearm aren't technically attached to each other, but it looks right in my drawing and that is really all I'm worried about.

Correct, you can just use the rotate tool and it'll spin around the vertical pipe. The loci that is part of the c-clamp that I built the symbol around stays at the center of the pipe.

 

Edit: You just have to make sure you select both the arm and the light since they aren't technically connected.

I just discovered that they were provided when @AWaters asked about them, and I completely agree. I think that reclassification would be great. Just to prevent confusion.

Exactly my thoughts. It's that "one other axis" that I was thinking about as well: the Tee sliding along the arm. And the issue of where the Loci actually wants to be.

 

Also, thanks for your workaround suggestions. Like you suggested, I have been doing reports using my own symbols which has always worked well and gotten the core of the data I've needed (how many sidearms / where are the sidearms).

 

@AWaters solution of relating the lighting device to the rigging position and jumping over the sidearm is what I'd personally do now if I needed 3D representation of sidearms. It sounds like making the sidearms rigging objects or hanging positions would be the next step. It's certainly the only option now to have 2 versions of the fixture symbol (with and without a c-clamp) for efficiency as well as accuracy. A long term solution could be the option to choose "clamp/hardware" from a OIP dropdown and have a selection of C-clamp/Mega-Clamp,Tee, etc. I'm sure that's been requested before so I'm drifting off topic.

 

Appreciate your responses and the discussion.

Sidearms are so common that I'm surprised that this hasn't been addressed before. But I also don't know how long we have been able to associate lighting accessories with lights. It's been a long time since I've used Vectorworks on a regular basis.

It's very much a theatrical workflow which to be fair is only a part of the Vectorworks Spotlight Users. In the UK we use De-Rig arms (Pipe) and I have noticed most users not wanting to bother drawing them.

 

We will take both your thoughts and suggestions moving forward.

@AWaters Is correct.  As a US based designer, the Side Arm (with or without the "Safer Side Arm") is a common accessory.  As it also is a replacement for the c-clamp mounting, it is vital to the shop order.  The steel must be ordered/pulled/replaced, etc.  So in my workflow, it is always a "missing" element that I must manually enter and calculate into all documents.   (including Lightwright) 

 

In today's world, the visual representation is becoming more and more important -- and taken for granted many times.  Rather than looking for a note or refence, the tech will just look at the drawing and hang the gear the way it "looks" >>> not the way it's noted on the side.  Add the fact that VW is a fantastic visual tool ... and 3D representations ... the mounting details become more and more vital. 

 

If y'all can implement the addition of these accessories that would be fantastic!

Hi Preston,

 

Alot of the sidearms you mention are in the libraries but under accessories. Now I don't think they should be accessories but rigging items. More on that longer conversation later. 

 

I will notify the content team of these. Also there is a new webinar coming out which will cover this workflow in great detail, look out for a Vectorworks webinar by Mark Doubleday. I would recommend you check it out.

 

Best wishes

@TomWhiteLight THX for the reply... I have searched and searched thru the libraries; both Accessories and Rigging. ... but unable to locate one.  I will try again! 

 

As an accessory >>> you would place the accessory and then associate it with the proper instrument.  Thus all paperwork and information will associate the sidearm with the appropriate instrument.  Also, there are several rental companies that install c-clamps as requested as the attachment point is not always the same.  And in this case, the Sidearm.  Inventory calculations change.   Even prepping for the hang, knowing how the gear will hang is needed. 

 

I just looked up what a "de-rig" arm is.  I've seen those also here in the US.  And those would be considered "rigging".  As you still utilize the supplied c-clamp on the instrument to attach to the de-rig arm.  Whereas the antique-style Side Arm is actually more a part of the lighting fixture once it replaces the c-clamp.  (Personally I would prefer the de-rig over a side arm!  I wonder what the cost difference would be... ???)

 

Looking forward to see how this workflow should work.  Great news.

 

THX~  P.

@BSeigel this is PERFECT!  And thank you for the Video Tour! 

  • Did you create this "Source-4 w/SideArm" symbol? 
  • The actual SideArm is NOT an accessory, but will create a different count of fixtures? 
  • Those with C-Clamps and those with SideArms?
  • Do you need one for each degree-type?

The City Theatrical Side Arm is a different creature... but will count the same. (?)

 

THX for the input!

You are very welcome,

 

"Did you create this "Source-4 w/SideArm" symbol?"
I did create a symbol for the sidearm/clamp that I nested in the symbol for the Source 4
 

"The actual SideArm is NOT an accessory, but will create a different count of fixtures?"

The sidearm is inserted as an an accessory, clamps can be set as accessories in 2021. For counting fixtures I would recommend using a worksheet that summarizes fixtures based on instrument type. 

 

"Those with C-Clamps and those with SideArms?"

The clamp came from the VWX libraries, I think I modeled the rest. Should be easy enough to customize. 

 

"Do you need one for each degree-type?"
I would recommend creating a symbol for each clamp/fixture combination

 

Hope this helps!
