Hi All,

I work for a partioning company and I am using Revit 2013 to create glazed partitions panels and doors.  Each panel is made up of many components, which are nested together so they can be scheduled.

At the moment I have created the components in both casework and generic model family.  These components were then loaded into a curtain wall panel family to nest together.  The reason for loading the families into a curtain wall family is because our partition panels do not have a set width or height, so therefore a curtain wall option allows our partitions panels to flex to chosen size.

Once I have loaded the families into the curtain wall panel family, I want to add a 45 degree cut void through a few of the component families.  Revit does not allow me to create a void cut through the families.  

Would anyone know of any ways in which I can achieve a cut within the nested family?  Or recommend a way to assemble our panel more efficiently.  I have read through the Revit families guide, yet still do not understand how best to solve this issue.

I have attached a sample Revit file in which I have tried to used Generic Model family to produce a void extrusion with no luck.

Thanks

Have you just changed your name?  This question was answered in a previous post:

Your approach is bad - don't use a curtain panel.  All families can be parameteric and that is what you should be using.  A casework family with all nested families being casework.

I haven't changed my name my colleague asked the same question before but failed to figure out. The reason why we use the curtain wall panel is so we can create a wall of desired height and length, split into equal number of panels and then load in our curtain panel which consists of casework families nested together. 

Surely the way you are suggesting we would have to load each panel individually and then copy it several times as our panels are used repetitively in a long linear stretch of partion. This process would be time consuming.

If we are to use the curtain wall method then can you please suggest a suitable solution for creating our panels with components nested within.

If you could help with this issue it would be much appreciated

The previous poster indicated these were basically casework elements nested in a curtain panel and he wanted them cut in that family.  I explained in that response why that would not work. 

Your question is a little different but you are still talking about voids cutting nested elements. If you are doing doors and partion type panels, please consider the following.  This can be curtain wall with the 'mullions' being your edge conditions and the panels being either doors, curtain panels or walls!  But curtain panels have explicit rules they follow and what you and your co-worker have previously presented will not work.

Why don't you give us a plan section and elevation of one of the proposed panels with the joining framing and maybe we can direct you better.

Thanks,

I will send an AutoCAD plan, section and elevation of an example of a proposed panel as well as a Revit file of the example. Did you want me to attach the files to this forum or to your email address?

Please find attached as requested; Plan, Section and Elevation in dwg format of a typical glazed panel we produce. As you will notice from the drawings our panels are constructed of small components assembled together at the top (Head Track) and bottom (Base Track) and side (Abutment Track) with glass. 

We need a method to create the components so that they can be assembled together to form our panel. When we schedule we want to see details of all components. The reason why we use curtain wall panels is because our panels are not fixed in height or width.

With the curtain wall if we have a partion span of 10m we can easily split the grid into equal panels and load our panels into it. We have experinced creating the panels with both casework and generic model families but struggled to use void cuts.

Could you please advise a solution to create a panel of our components which can then be loaded into a curtain wall and yet have the ability to void cut panels to create a panel with a 45 degree angle.

I hope this information is useful and we would really appreciate your help.

Neither one of those files tells us very much.  We need an image - plan and elevation - with maybe some notes showing us how this thing might look and be repeated.

These can just be curtain walls with specialized mullions (no mullions in glas to glass places).

Could you  possibly expand and explain in a bit detail.  We have sent you images, plan, section and even the revit file. Yet we still do not know how best to create these panel.  

If you could kindly tell us in step by step ...as in what family to create the component...what family to assemble the components before loading into a curtain wall...it will be really apreciated.

You have been helpful..but your short answer replys do not explain and demostrate us how best we can achieve our goal.

So please if you can spare some time to explain in step by step...we will sincerely appreciate it.

Look at some of these tutorials.  http://www.youtube.com/playlist?list=PL557EAE1AE6EF1C01

What WWHub is saying is that you just dont put a mullion in where the glass meets glass.  I really don't understand where the casework families or nested families come into play, from the pictures that you sent it is simply a curtain wall.

ok..so your saying we dont need to nest familes together.  Then how do we create the panel.  which is made of the many components nested together.  what family would you create the components (see the cad file my colleague uploaded)... the reason for nesting was so when we schedule the curtain wall each components is scheduled individually.

There has not been any CAD file uploaded in this thread.

You Revit families and your images don't tell us anything about what you want to schedule or what is parametric and what isn't.
