Hello everyone. I have a question about opening and closing parametric bi-fold doors so that the 3d panels are operable for views. I want to be able to open and close the 3d panels via percentage. I have placed the bi-fold door family within a curtain wall system as the curtain wall panel (Will this be an issue?) The door I am currently using has 4 door panels.

Ideally I would like to create the option to fold the door panels 2+2 or 4+0, with percentage opening between closed and 100% open.

Would be so grateful if someone could help me. There are no tutorials posted on the web currently that cover this.

I have attached the door that I am curently using. The door panel is nested within the bi-fold door family. 

Thanks

Slejj.

I believe you would need to put an angle parameter dimension on your doors.  The file that you attached does not open your family.

Revit does not work dynamically so either the door will be shown according to how it is set it to show from the family.  Typically, most users show the door open in plan (might be adjustable) using symbolic line work and closed in elevation and 3D views using model elements. 

You could create type based families that have different settings for the angle of the model components.  You can also to do this with instant parameters using different model components that are switched on/off or with adjustable angles.  << Some users have made these for door open / closed.  But in all cases, it will be a static setting.

To create a family that partially opens that has multiple leaves will be difficult because the hinge point moves.  Download the Families Guide from the AutoDESK website.  It will show you how to use reference lines to control angles of elements in families.  I must warn you.  This can be quirky at 90degrees.

I did a quick test, and it does look like it's possible to create a parametric bi-fold. I only tried it with two panels, but that worked, and adding more should be possible. I used nested families for the panels, and locked them to ref plane intersections, not to each other (see attachement). Then I used some trig in the formula to drive the Width parameter (in a full family this would be a separate 'panel open width' parameter). It seems to work just fine.

As WWHub said, Revit doesn't seem to like 90° and 0° angles, but that seems to be confined to testing inside the family. Once the family is loaded into a project, it seems to (generally) work ok. If any angle other than 90 or 0 is working in the family, 90 and 0 will probaly work in the project.

I created this door in Mar 2010, maybe this can help you: http://www.revitcity.com/downloads.php?action=view&object_id=9052

You can open and close in any view, it's 100% parametric, 0° angle to open completly or 90° to close.

The formula for a door swing based on a percentage value is simple. See the attached image. This assumes 90 degress is 100% open.

Thanks a lot to everyone who replied to my thread. I really appreciate your help. Thanks Typhoon for the door file. Thanks Tkennedy and

jterrell for the formulas and diagrams. I will combine those and try make a 4+0 with my own family. 

Cheers
