Das Boot! RC1

[mjdanowski]

I have heard a lot of people request this, and have been in the process of upgrading my old rigged up version of it into something a lot more usable. Therefore, I have decided to release the "boot" takeoff that I have made for rectangular ducts.

Some key features:

- Ability to change angle of sloped "boot"
- Ability to change the protruding length of the takeoff (whilst keeping the boot angle specified)
- Ability to "switch" boot facing without having to deal with the mirror command (because that generally screws something up)
- Insulation and lining support
- Festive family name

Please post here or send me a PM if you experience any errors/problems.

In the spirit of one-upping Matt , I saw this one and I figured I'd post a version of this takeoff that I helped build when I was in support.

This one has all sorts of bells and whistles, as I got engrossed with fixing it one afternoon, and my trig hand was strong that day.

It adheres to SMACNA standards OOTB (Takeoff Length = 0.25 * Duct Width, 4" Minimum), but allows you to override both the length and the angle if desired, so this is really all that you need. To accomplish this, there are a bunch of nested IF statements that drive the dimensions, have fun going through it if you'd like.

I actually forgot about this family until I saw this thread, now it's time to get it into the product.

P.S. As this is not an officially released piece of content, it has not been through our QA process. Therefore I cannot gaurantee its behavior on all cases.

These are great, thanks guys. I'm having trouble getting them to work on vertical duct. I can rotate the fitting so that it works, as long as the duct is square. But if the duct is rectangular, the dimensions of the fitting do not change when it is rotated so it looks mismatched.

Also, any modification to the vertical duct being tapped into reverts the fitting back to its default orientation.

Just some input, I'm not complaining......really, these are great to have, thanks again!

Whose version do you get that error with?

[dmb.100468]

Sorry, I should have specified.

I get the condition with both families.

WOW! Christmas has come early!
Thanks Kyle / MJ. Looks like just what we need.
Interesting post from DMB re not working with vertical ducts. I've not had a chance to experiment myself yet (only just seen the posts) but I would hope that if there is a problem here, a solution wouldn't be hard to find. They are a "must use" fitting in risers in a multi-storey building.

Thanks guys,

Only problem is....it's imperial. I need a metric version.
Any suggestions?

I am a little dumb with metric in Revit as I have never used it before, but can't you change your project units to metric and it will just scale accordingly? There aren't any parameters that I know of that is based upon dimensions, it is all ratios and additions.

You're correct Matt. You can also change your Project Units in the Family Definition so any dimensions can be entered in Metric units.

For my version of the Family, I set the length of the Boot to be 1/4 * W of the takeoff down to 16" width, after which point I lock the length to 4". I would suspect that a Metric version would have a different length minimum that 4". That would be all you need to change in my case.

Well, a few weeks later and we have had a degree of success with this fitting. (see attached)
It looks fine, but there is still one problem, it doesn't actually "connect" to the main duct. It 'snaps' to it, but it doesn't actually become part of the system.

Any suggestions

Thanks,



Michael
