Hi everybody!

I am trying to create a custom lattice family by using the template of a metric curtain wall panel.

I am able to create a solid panel (I know, so easy), and after that I start to modify the extrusion by using as a template a cad drawing imported into the family.

In theory all is ok, I can make all the holes necesssary for the lattice, and I can import this family into my model. The probkem staets when I try to change the glass panels of my curtain wall by chosing this lattice I have prepared. Impossible!!

Any suggestion? How can I do to create this custom lattice that I need?

Thank you!

Not enough information. 

The problem will be in your solid panel family.  You probably have geometry or voids that can not be created when the family is flexed in the project.

Thank you for your answer.

Surely the problem is in the fact that you point out, the lattice I had modeled had lots of complex voids -it was an arabic pattern- so surely it was impossible to flex when inserted in the curtain wall.

I have solved the problem by doing a model in situ, but that meant not using a curtain wall and doing other solution.

Anyway, thank you again and if somebody has any suggestion or has faced a similar problem before, please comment it!

Did you know that you can place any wall into a curtain wall panel location?  So the 'wall' could have been defined like you did with uour panel and you could have had a face based void family to cut holes in your wall.

I didn't know, I suppose that I should transform before the in model component into a wall.

I will try!

Thank you again

Using the process I described....

Pick the CW pandel and change it to the wall you re-defined.  In my case, it was a 1" solid wall.

Add a face based family that cuts the host.   Mine was much bigger than the area but no problem.

Hello WWHub!

After some weeks in which I was working on other projects, I started again to work with the pannels and lattices.

I have tried to follow the process that you told me but I can not create a face based family. The only way I found to create that was creating a panel with the exact dimension that it will have in the curtain wall, so it has not to flex.

Could you give me a more detailed explanation please?

I have seen in more recent posts that I am not the only one working in the middle east facing these problems, here lattices and mashrabiyas are everywere... Revit should create a plugin to design these features!

Thank you,

Alarife

The process I used was all wall based, not curtain panel.   With CW's, you can assign a wall insetead of a curtain panel and it will flex with the curtain wall.  Then the void is a face based family applied to the face of the wall. 

To make the void, create a new family - generic, face based.  Create the void form as an extrusion and make it deep enough to cut your wall panel.  Set the void to cut the host.  Load it and place it.
