Parametric frame

Anonymous — Fri, 10 Jan 2020 13:36:41 GMT

HI everyone
I want to ask about your opinion with my problem. I need to create simply frame from various profiles.
I want to create axis frame. than to every axis assign corect profile ( which i draw). With changing of the axis frame the profiles are changig with it. Than i need to create for every profile parameter length and color a get the bill of material.
I tried curtain walls, generic componet but i am new at revit and i need your advice what is the best way.
Thank you

Perhaps you don't need to create it. Look in the families library for Structural framing, where there are trusses that have been built where you can add a profile. If these frames are not the correct type, use one as a starting point.

I think the structural frames are not good for me. look at my frame - every color means diferent profil with

information about the length. Do you think i can make it with structural frame?

Is this for a school project or something else? What's the purpose of the construct? Does it got a name? Got pictures of the finished product?

It is not a school project. It is a facade modul. I need to define basic geometry and then get bill of material. I need the amount for every single profile with length and colour. Curtain wall doesnt work for me because Revit devide every vertical and horizontal profile in croosection-than i can not get the right length for the profile. now i am trying the structural frame.

I still don't quite understand. Sounds like you want to subdivide components for more accurate accounting. Maybe there is an application for Parts here?

Just model it? Using the different frame profiles where you need them w. beams/columns. You can put it in an assembly or group then if you like also.

Using some sort of family and parts seems a bit farfetched tbh, but... maybe.

How do you want it to be parametric? It is a repeating frame in the project I suppose?

Parts seems farfetched? Really? I'm talking specifically about Dividing Parts. That's what it sounds like the OP is doing. But, maybe I'm misreading.

@barthbradley I know what you mean, i wasn't dismissing the idea. Just wondering about these questions above though, and if that would be the right approach. Edit: farfetched perhaps was not the right choise of words...

Use a curtain wall.
- Create different mullion profiles and load in project
- Create different mullion types and assign profiles to them
- Create a curtain wall and assign different mullion types for borders and interior
- Draw curtain grid as you want
- if you want to change a specific mullion to a different type, select it, unpin and change

...but then you can't create the mitered corners.
Maybe you can create a structural truss for it, unpin 1 of the profiles and change that ~~& group it~~ (will give inconsistent group error).

I have no clue what that kind of façade element is that but I think what @ToanDN suggested is the most practical.

Looking at the image, it doesn't seem to have mitered corners … curtain wall with blank panels 100%

Re: Parametric frame

martijn_pater — Sat, 11 Jan 2020 09:18:48 GMT

It is practical, but I still have the question; how does it need to be parametric?

To just make a frame, with mitered corners, I think I would just model it using structural framing profiles, set justifications as depicted, and just make a group out of it probably...

martijn_pater — Sat, 11 Jan 2020 10:17:33 GMT

@AnonymousOw, actually you could load your structural framing profiles/families into a 'complex and truss' family, and model the frame there. Actually that's better then grouping and you could make it parametric also. Although I don't know about scheduling (parts?) for that, but should be doable?

@martijn_pater

I did say I think...Practicality is something which is RELATIVE to the user and not a assertive benchmark.

If you find working with structural framing profiles, setting justifications, using groups and nesting into other families for a one off set of elements, others might jump in and say

Do it all using in-place components
Do it using an adaptive component
Do it using a pattern based family applied on a custom pattern (one guy asked about those sometime earlier this week)

I personally find it more practical to use an OOTB tool which can offer the same output without having to blow my head off wondering what I can do more for it to be more complicated. Hence, I second @ToanDN suggestions

Nothing personal 🙂 I like you and Toan eaqually

this solution is not good for me. revit devide all profile at the crossection. (I think they need it for the the glass and panel geomety).

this is solution but it is to complicated.

Re: Parametric frame

martijn_pater — Mon, 13 Jan 2020 08:37:45 GMT

@AnonymousToan's suggestion is the most workable solution probably depending on what you need to do.

I tried to find another solution for you creating a frame as in my previous suggestion, loading four structural framing elements into a "complex and truss" family. But this is somewhat complex it seems.

Getting the materials from each profile doesn't seem that complicated, but I kind of got stuck with getting the structural framing properties from such a family for each profile, ie cut length. You could add more parameters to the family yourself for scheduling for that, but it would make sense that you could get these structural parameters for each profile from this family somehow...

Maybe structural columns and beams?

Re: Parametric frame

martijn_pater — Mon, 13 Jan 2020 10:30:36 GMT

@binYeah, suggested that in post #7, but it's still unclear to me how it needs to be parametric... It is possible to create a parametric frame using my above suggestion and then schedule everything through shared parameters... it is a complex solution though, if you want to do it this way... I can make a step-by-step later... BTW You could just use framing, no columns.

I try this solution. first i have to create my own profiles and then model the frames.
Parametric - my first idea was to create lines grid and to every line assign a profile. There will be two variables length and high and with this variables change the whole geometry - geometry of profiles and glass/panel.
