i have a package unit on the roof, and on the concrete foundation i shall place the package units on spring support to hold the weight
(please picture attached)
am not really great in modeling but i need an advice (step by step) or if any one can send me the family file for the the spring
plese check the attached file and let me know if it is can be done on revit or no ?
Solved! Go to Solution.
Life is too short to be modeling the spring unless you are specifically told to do otherwise. We (or I) show *representations* of the units. I love getting manufacturer models and striping away bolts and other unnecessary stuff just to show their rootop unit. Having said that, the spring *can* be modeled. I'd use the sweep extrusion myself.
FIrst off - what do you want/need from this Family? Would it have to be parametric (change sizes)? Is it going to be scheduled as an individual component? Is this a general representation or are the details/dimensions crucial? We need to determine the criteria in which this family will be created.
Sorry if I came off a bit rough. When I am tasked to go to XYZ manufacturer website to get their revit family, we find it to be overloaded.
If we step back to look at the overall goal - that is of showing a *representation* of the product that we are specifying on our drawings, then things such as:
All these things make the family "heavy" and can sometimes weigh in larger than the actual project we are working on. Again, recognizing that the piece of whatever we are modeling is what *we* spec, doesn't necessarily mean that that will be the piece of equipment that will end up on the finished project. As long as the manufacturer holds to our designed parameters, their unit may be a totally different shape.
This is why I am a HUGE proponent of generic equipment. Just something to show to the architect. 9 times out of 10, the BIM will go no further than the architect, so the client will not be doing elaborate flythroughs so that one can see the intricate details of the model. Rather, a box to the dimensions that we specify, if it has some sort of economizer on it, etc. will do the trick for us.
And if the equipment is to be out of sight (concealed in ceiling, plenum, attic, etc.), then it is even more generic. At the end of the day, if we engineer and design the unit to work under the tolerances specified on our schedules, including duct opening sizes, pipe sizes, etc. - if we have done all of this, then we, in my opinion have done our due diligence.
If you are wanting the spring for a detail, I've not seen 3D details. If you are working for a manufacturer, then please take the comments above as constructive and consider making changes. I'm sure I'm not alone when it comes to "heavy model" concerns. if you *truly* need to show that sort of thing (which I said in my previous post it can be done), Google it and you'll find people as far back as release 9 Revit asking that exact same question. But I would consider using a program such as Inventor, where it is second nature to design a spring and will take 1/16 of the time it would take to model it in Revit. (my opinion). And we all know that time is money.
Off my soapbox.
Two more questions: #1: how versed are you on Family creation and #2: what version of Revit are you using?
This shouldn't be too difficult - aside from the spring, of course. I'm not entirely certain how to go about making a "true" spring in Revit, but I've made "reasonable Facsimiles thereof" a couple of times which only takes a couple minutes. Upon close inspection (in 3D), the imperfection may be noticed. If you're interested, I can post a short video. But I would also say to consider Rick's advice - not all details are necessary and over-detailing will only prove to bog down the Family and bloat its file size. One spring shouldn't matter terribly, though.
See Chronicle Video below. Note that at the end, you can easily see the imperfection when the spring is spun, but otherwise it should be pretty unnoticeable. I would recommend using Reference Planes to host the various extrusions (other than the spring). You can either create the spring as a nested Family or draw a Reference Line at the top, bottom, and/or center of the spring and create a Group, so it can be controlled and constrained, if need be.
