2) Change the "Length" parameter to 8'-0" via the "Family Types..." button.
Just like this...
Good so far...
I am using the Double Door & 2 Drawer, as you can see.
and set (unless we previously set this) Line Based Families' "Family Category to be Casework, like below... But if not we can do it anytime and then reload!!!
This goes for exposing materials, etc., etc., ...1) New Family “Generic Model” (Square Column)
a. B Wd (B = Beam, C = Column, etc.)
b. B Ht
c. B Lng
d. C Wd
e. C Dp
f. C Top
3) Create Square Colum
a. Use the 3 shared Parameters: C Wd, C Dp, C Top
4) Create Round Column (Save As ???)
a. Use the 3 shared Parameters and Add:
b. C Rad (Make this equal the following formula)
i. = C Wd / 2
5) Make
a. B Wd =
b. B Ht = C Top+1.5
c. B Lng =
d. C Wd =
e. C Dp =
f. C Top =
6) New Family “Generic Model”
7) Create Beam
a. Use the 3 shared Parameters: B Wd, B Ht, B Lng
8) New Family “Generic Line Based”
a. Make Length 8’-0”
9) Insert Beam Perpendicularly to length line, Place it and Lock.
10) Copy it to the opposite end & Lock.
11) Add & Place Columns
12) Create a ‘Family Types’ Instance Parameter: Column Type and choose Generic Models. (or change column & beam families to their actual category and use those here)
a. Select all columns and set them to have the parameter Column Type.
13) Array 1st beam 2’-0”: Group & Associate, Move to 2nd, Constrain.
a. Select the Arrayed Beam and select the Array Control Line and add a Parameter: “Number of Beams”, Constraints, Instance and OK.
14) Dimension the 1st & 2nd Beams
a. Make it the Parameter “Beam Spacing”, Constraints, Instance and OK.
15) GoTo Family Types and add the following Parameter:
a. “Maximum Beam Spacing” , Constraints, Common, Length, Type OK in this dialog, then APPLY at the next; (Not OK…we want to stay in this dialog for a minute).
16) Make the Parameters the following Formulas:
a. Maximum Beam Spacing = 4’-0”
b. Number of Beams = Length / Maximum Beam Spacing
c. Beam Spacing = Length / Number of Beams
3. On the Modeling Tools choose "Void Form" and if you need the metal pan similar to the one I used choose the Void Extrusion... In order to draw the lines delineating the decks 'corrugation' I picked the floor plane that is staring at me (from the elevation view). 'Tab' may need to be employed to get the correct face... don't choose the top of the floor!!!
4. Next, using those lines (obviously) draw the shape to be voided out of the floor.
5. Just before finishing the family make sure the extrusion is long enough to cut the entire length of the floor in question, then using the "Cut Geometry" tool...
Cut the void from the floor. Finish the family and now a better "voilà"
Oh and as you can see from above a normal shaft opening cuts our floor...A truly elegant solution. Thanks Revit!!!
