bridle

[matteo17]

good evening everyone I can't use the two-way bridles I feel better in the leg with the adjustment spots the engine point does not move the adjustment of the chain I would like to use 2 m chians with 7 cm rings I am certainly wrong with some settings do you have any advice thank you

[jcogdell]

Currently there are no 2m chains or 7cm rings in the stock bridle parts library that the bridle tool uses to configure the steel for a bridle.
 

You can add new parts to your own custom bridle parts library with slings and other objects by opening the Stock Bridle.vwx library file.

Its located in your application folder>Libraries>Defaults>Stock Bridle Material

and can be edited like any other library file.
Bridle parts should be stored in the file resources and have to have the BridleItemRecord attached to them to be classed as bridle parts

The record defines the parts behavior with the bridle tool and object.
the easiest option is to duplicate an existing part and edit it to create the new part.

Once you have added the new parts save the file back into the same location, make sure to create a back up of it as well as it will likely get overwritten if there is a update to the default libraries.

open a new empty file,

open the bridle parts manager and hit the update button to import the new parts into Spotlight.

You should then have access the newly created bridle parts

 

Let me know if you have any more questions

unfortunately I haven't solved it I can't figure out how to create a new stac chain, but when I choose the material from manage bridle parts for the bridle I saw that I can modify the chain from there both length (min and max) and the links

[VIRTUALENVIRONS]

Could you post a picture of what you want to create, from any source.  If we could see the problem, it can probably be solved.

Hello I have to create a two-way bidle, the beams are 50cmx20cm, 2mt basket, distance between the beams 4m, fixed leg of the bidle 4m steel cable - leg with 2m steel cable adjustment and 2m stack chain, apex height approximately 13.5 m

[matteo17]

this is an example I have to insert the bridles to have the regulation of the chain in the construction I can't figure out where I'm wrong in the settings, basket 2m leg with adjustment 2m + 2m chain stack fixed leg 4m apex height 13 m anchorage height 16.5 m

This is a long standing known issue with the 3D representation of bridles.
its a purely visual issue that doesn't affect the bridle parts calculation or configuration, only how the part symbols are used to draw the bridle when the simplified view of the bridle is turned off in the properties

Its caused by a combination of 2 issues

• Bridle parts are basic symbols not parametric objects, this mean the bridle tool can't adjust the parts geometry to display things like wrapping around a beam or adjust a chain to show only the correct number of links being used.
• the second issues leads on the from the first, the bridle tool doesn't compensate visually for the bridle basket dimensions and draws the parts from the rigging point down to the apex, which results in a visual errors when the bridle parts are  are correctly configured in the bridle configuration dialogue. Either the part overlap at the apex or there is a gap

The limitations of this 3D view mode is why the bridle assmebly diagrams where created, these provide a far clearer and more accurate representaion of how the bridle should be assembled, including the length that each chain must be adjusted to to correctly configure the bridle.

so even if i don't create a stack chian from mt t but i just change the length when i insert it i will get real adjustment ? che i.postazioni devo usare per relolare in modo ottimo il mio bridle ?

Is it possible to have the "Stock Bridle.vwx" file in workgroup libraries? I just did a test and it did not work on first try.

[jcogdell]

@Stefan B.
Yes this should be possible. you may need to get rid of the default version

 

[Stefan B.]

On that note, does Braceworks calculate by the length of the parts or by the length of the Bridle settings?

 

Edited May 31, 2024 by Stefan B.

[jcogdell]

it does both, the 'leg length x' fields are the length the bridle tool calculates as the ideal leg lengths based on how the bridle is drawn and the 'Part length leg x' fields are the actual length of the legs based on the bridle configuration.

My understanding on how VW Workgroup folders/files ("Default Content") work is that if you have a file with the exact same name it will use the version that is "closest" to the user.  So User Folder > Workgroup Folder > Application Folder.

 

If you want to use the version in the Workgroup folder preferentially, then you have to remove or rename the version in the User Folder.

I did a test(accidental) on Friday before your reply. And Braceworks does not change its results based on the parts used in the bridle.

I have copied a version of BridlePartsList.xml and put it in my workgroup folder. I tried to rename the one in my userfolder to BridlePartsList-backup.xml. 
When i update the parts manager it then just creates a new BridlePartsList.xml in the userfolder and does not use the one in my workgroup folder.

 

[Pat Stanford]

The Default Content is standard Vectorworks files (VWX) not xml. The XML may not work from the workgroup folder. @jcogdell can you comment on the requriements for the bridle XML file?

[jcogdell]

The xml and the bridle part library are 2 seperate things.

The library is a user editable vwx that stores all the bridle part symbols and their basic data, this is what users should be editing and customising to control their own bridle part libraries. Normal workflow is that this will replace the default bridle part library once edited and saved into either a user or workgroup library as described above.
 

As far as I know the xml is created by the Bridle parts manager whenever it is used to edit the bridle parts library, and will be over written everytime the manager is used. This stores the application availability of parts from the library based on editing the vwx library file (important to note not the curretn show file). Because this is application preferences this is stored in the user library folder and should not be moved or manually edited.
 

[Stig Runar]

@jcogdell Okey, so this is working now. But it looks like it just adds the content from the file in the workgroup folder and does not overwrite the content from the default installation. For me I just want to remove all symbols that are not metric. So I delete or rename the Stock Bridle.vwx in the default installation?

[jcogdell]

there are 2 options,

1. Deleting the file from the application library folder, however since the library will be reinstalled with every update, you'll have to do this again each update.
2. The better option is to open the original library file in the application library and use the manage bridle parts dialogue to uncheck all the imperial parts in the use column. save back to the original location. Then update you application preferences (in this case the xml file in the user folder) by opening an empty file and hitting the update button in the bridle parts manager.
   This requires a bit more work upfront but you shouldn't have to worry about any content updates, and has the added benefet that the imperial parts will still be available if you need to coordinate with a US rigging team or production, they just won't be used automatically by tool to configure bridles.
