Need assistance building and or editing familys. I need a family to use for embed connections for precast walls, columns, beams, and double tee's. I've seen a few familys for steel connections. but none as yet for precast. What I need to create are plate connections with various plate thicknesses widths, and lengths also these plates require a parameter that would allow for chamfers and holes as well as various rebar lengths, sizes, and quantity. Anyone have any success creating anything similar to what I have described . Any help would be greatly appreciated.

What do you need is not ONLY one family, it's a bunch of families, to control the holes you must create a voids with arrays and lot of parameters to "holes as well as various rebar lengths, sizes, and quantity."

Do you have some screenshots to figure out what really do you need?

Typhoon is correct you will need multiple families to achieve this.

 

The end result can be one family but it will need to have the other types nested into it. 

 

This is in part due to the limitations of an array parameter. (The quantity must be an integer greater than 1) 

 

I would highly recommend using the "face based" family template.  This will allow you to place the plates on any face of an object regardless of its category. (wall, column, beam, etc)  It will even align the plate to curved surfaces. (The plate will still be straight)

 

Based on what you've described I would envision 7 families:

 

  • Host Family - contains all the nested families listed below, parameters include embed type, plate material, plate type() stud material, stud length, stud Ø, edge distance width, edge distance length, Number of studs length, number of studs width
  • Single Stud - Contains nested stud family and both plate families. Parameters include plate width, plate type, plate length, plate thickness, stud length, stud Ø, stud material, plate material.
  • Single Row Studs - Contains nested stud family and both plate families. Parameters include plate width, plate type, plate length, plate thickness, stud length, stud Ø, stud material, plate material, number of studs length.
  • Multiple Row Studs - Contains nested stud family and both plate families. Parameters include plate width, plate type, plate length, plate thickness, stud length, stud Ø, stud material, plate material, number of studs length, number of studs width.
  • Flat Plate - Contains parameters for material, length, width, and thickness
  • Chamfered plate - Contains parameters for material, length, width, and thickness
  • Stud - Contains parameters for stud material, stud Ø, stud length

 

As with most revit practices there are multiple methods for achieving a single goal.  You could skip a few steps and leave the families seperate rather than nesting them.

I would also recommend taking on this family yourself.  It is complex in its nature but if you trudge through it you will gain a pretty advanced knowledge of families and their capabilities.Edited on: Wed, Jul 30, 2008 at 11:22:55 AM
