Slopes in generic model by void

[j-davelaar]

Hello,

This is my first post and I hope to find guidance here.

My company makes stackable units. These units their construction is a frame of structural columns and beams with a concrete floor in between.

One of the floors, which I need to create, has 2 sloped areas in it. I was planning to make these slopes with a box-shaped void, which I would rotate in 2 ways to make a slope. The highest point is -6mm and the lowest point is -30mm.

When I try to rotate my void, it says "can't keep elements joined" and then it doesn't cut my extrusion.

Any ideas on how to solve my problem?

How about modify subelements? Possibly combining/joining multiple floors... edit: misread, you're using a generic model apparently, why not use regular floors?

[j-davelaar]

Would be a great option, but unfortunately this doesn't work for my generic model

[martijn_pater]

It's a one-directional slope? Not sure why you wouldn't be able to cut with the (in-place?) void... You could share the family/model to have a look perhaps...

[j-davelaar]

Well the void must be tilted 2 ways (see image of wanted result), but 1 way already gives errors.

Hereby the file and how to slope it (back view). I place the rotational point at top left (see image) and I rotate it at the end of the void, 2 ref planes down.

Like the attached? *can't seem to add/upload as image.

That would be the best possible outcome, but this would also be fine(see image).

Just what is doable.

[martijn_pater]

You could try building it as adaptive component family, not sure how you'd want to parametrize it though. It's a somewhat different approach I suppose. Otherwise you'd have to build it up from several joined solids, while making your section extrusion from different workplanes (not from section).

Or, maybe do build it in a project file using the modified subelements functionality you could parametrize that aswell using global parameters...

edit: hmm just thinking if I'm not overcomplicating it...

What is this for kind of family that you created?

Welcome to the forum. 

You know, there might be a better way to model this Revit/BIM Content.  You wouldn't by chance have any company/product literature on these stackable units that you could share with us?  Pictures, specs, what-not?  

[j-davelaar]

Thank you!

The choice of setting it up like this, shared nested parametric generic models, was a choice of the BIM consultant who is advising us.

Until this point it worked perfectly fine, but this problem is a minor problem.

I have added an image of the stacked units in Revit. This will be the structure family.

In the next year I will have to make a wall family (generic) and a roof family (generic). After that some small components like a radiator, toilet and airconditioning.

After that I will focus on adding information to the families which can help other people within the company do their job better or easier.

[martijn_pater]

Hmm, well I think I would sooner do something like this with groups and/or (bound) linked model perhaps, not as a family although it is an option ofcourse. But much like recurring questions for how to do hotelrooms such as this one ie. or storage units I think like this topic...

[j-davelaar]

@martijn_pater , I do understand the thought, but model grouping is more for interior design, isn't it? The most important about the units I make is that the modellers must have a list of default wall options, a list of default floor options and a list of default roof options, so they can quickly create the desired building of stacked units.
