Hi RevitCity community!

I've been following your Forum for some time and have learned a lot from your answers and tips&tricks, but so far I've never made a single post.

Now I need help from you and hope it will not be a problem for someone to direct me to a right solution. I am using Revit Architecture 2014.

I have to make a wall opening with chamfered(?) corners (attached file "rp1"). I would like to have the opening parametric, since I will have to use it on my model more than once, but with different opening width and height.

I tried to create a new door family, made the opening with void extrusion and I chamfered corners with void sweep. Problem is that sweep profile (trinagle) is not the same on sides and on top of the opening (on sides is right triangle with sides 60cmx40cm, and on top is isosceles triangle with two sides of 40cm). Attached is result :-P

Then I tried to use just void extrusion and I created custom profile, but do not know how to get top of the opening chamfered.

Please help! Thank you!

Create a simple, face based void family with the void set to cut it's host. 

We have such a family that we call a wall nitch.  The width and height are controlled by reference planes located by instant parameters and the depth is a type parameter.  We can place this on any surface and adjust it from the place-ing view.

• Start with the face based template
• Add your control reference planes in plan view
• Create your void... 2 parts, sweep around the edge for the chamfer, plain extrusion for the depth set to a type parameter
• cut the host with the void.

Thank you for your answer.

Other than the different template to start with, steps you described in your post are basically the same I mentioned in my first post.

Will using different template solve my problem with meeting void sweeps that have different profile (see attached image)?

I see your image but it has no meaning.  If that's not what you wanted then your procee is wrong but you don't tell us what you want.  If you want the sweep to turn the corner...(miter)... then it needs to be one sweep - not 3.   ONE PATH.

Yes, I would like that sweep turn the corner, but can not do that by defining just one path because top sweep void profile is not the same as side sweep void profile. The top sweep void profile is right triangle with two sides of 40cm (isosceles triangle), and the side sweep void profile is a right triangle with sides 40cm + 60cm + hyp.

Then don't do it as a sweep!  Do it in segments....

Because this is so special, you can do it all in place in the model if it is one of a kind location.  If not - do it in a family.

I need that opening on several locations, with different opening width.

Could you please suggest me in short lines how to achieve my goal?

Thank you.

A user from other Revit forum helped me with my problem. He used door based family, but instead of using voids to cut the wall, he built out he masses.

I customised his revit door family with my parameters. Attached is one of probably many solutions to my problem.
