Hi Everyone,

I'd really appreciate some help!

I have a corbel foundation family that mitres at corners using the modify - geometry command but when I add this to the base of another structural element it won't mitre...do you know why this could be?

I have also got a family with some mass concrete and dry pack modelled which would go under the existing corbel footing - I have them as separate families as the corbel itslef is existing and the new mass conc is new construction and Revit doesnt seem to allow 2 phases in a family.

The same problem occures when I add this family to the model under the corbel - unless there is a gap, the elements won't mitre!

Help! These families are going to be used in pretty much all of my projects so am hoping I can get them to work.

Any advise will be great, thank you!

(I have attached the families)

I don't think you did your foundation the correct way.  I would have done this as a profile and swept it around I think.  You are not going to get it to miter the way you have done it. I don't know what the modify-geometry command is that you are refering to??

I also don't think you need to create a family for the concrete and dry pack, you can do this as a perhaps a structural floor or wall I would think.

Thanks for this.  You may be right.

I simply took a standard Revit ground beam family and edited to suit, so it may have some errors.

I pretty much used the same way of modelling as some other corbel families I came across and modelled void extrusions and locked them to some reference planes.

The command I was refering to was the beam/column joins command, which works but not when in touch with another element.

The conc mass and drypack only took 5 minutes to creat so kept the same ref planes etc as the corbel family as they will link hand in hand with eachother, but, yes thanks, will keep that in mind for the future.

For now I have managed to solve to problem by just drawing a ref plane, and cutting the corbel to the plane, but as I will have this set-up in most of my projects it is time consuming.

I will give the corbel family another go using the sweep command rather than building it of extrusions and see if that helps.

Thanks

So I tok your advice and made the profile and used the sweep command but the only difference I can see if that the profile is modelled as one, and I had mine made up of sections.

I still can't manage to get it to mitre like a normal beam/wall

What do I need to do to the family to allow this?

Thanks in advance
