Multiple specs in the same service.
« on: Apr 16, 2019, 10:50:36 PM »
Is it possible to have multiple specifications in the same service? My idea is to have templates, one rectangular, one round, but it looks like you can only set one specification as a default in that service. This doesn't work when I load the service into Revit-setting the spec at the default for rectangular means I have to manually select spec and material for every round piece, and vice-versa. I guess I can split them out if this can't be made to work.
 
All suggestions gratefully received...
I didn't touch it.

Your spec should contain both Rect and Round in the same spec....and if you're unlucky enough to live in certain areas of the country...Oval too.

A single spec is used to handle all shapes.

This does mean a lot of redundancy in areas, it would be great to be able to apply a different spec per shape but it doesn't work that way.

The only other alternative is a separate service per shape which does not seem like a good idea.

Darren, I'm building my specs per the pressure classes laid out in SMACNA, so they're going to be different for rectangular and round. You answered my question though. I've got my specs and rec & round templates built, it's just a question of copying & pasting.

Thanks,

If I'm understanding you correctly, you're building separate service template for rect/round?

I get SMACNA has different specs for rect and round. But a single specification can contain both, rect and round specs.

Create a new spec. One of the dropdowns below the name shows the "Shape". This is NOT assigning a shape to the spec.

Set the drop down to RECT. Add a few entries. Now set it to ROUND. The bottom of the screen will change columns. Add a few entries.  Now change it back to RECT and you'll see your original RECT entries.

This is similar to the STRAIGHT/FITTING/BOTH dropdown as well as material.

However, in the case of material, while you CAN have different entries for different materials in the SAME spec database entry, it's best practice to build a SPEC per material.

You should be able to do all shapes in the same service. The only issue with Revit is you cant really have multiple materials in each spec. After parts are drawn Revit only gives you the ability to change service, not spec or material. Because you must specify the spec in the service, it requires you to make single material services and matching spec files.
