parametric row seating

[mocito.agostinho]

Hi,

I am trying to create a parametric seating row with a Generic Line Based family.

If you check the file for the Lenght (default) parameter, I am multiplying it by the Arm Distance (600mm) so that the pattern repeats while I stretch out the line.

=Chairs * 600 mm

I want to add a parameter for the Arm Distance linked with the actual seat so that if I make the chair wider the pattern would adjust accordingly.

=Chairs * Arm Distance3

This way I could adjust the chair width and Line Based family all at once.

However, I am finding that when I add "Arm Distance3" to the equation the Line Based feature stops working.

What am I doing wrong, or cannot it be done?

Cheers,

J

I looked at your family. With some small modifications you can do what you want.

See attached screenshot.

I locked the second chair to the right reference line, added dimension (as parameter will not attach to the existing dimension).

To the newly added dimension I added a parameter (arm distance3).

You now can vary arm distance and chair amounts.

As I am working in version 2014 and you in a previous version it is of no use to attach the modified family.

Works as a charm, thanks. 🙂

One question, though.

After loading it into the project, shouldn't the number of chairs increase while dragging the line?

The way I have it, the only way yo change the number of chairs by typing in the parameter field.

hi

1- Reference Line Seat With reference to the line Lock.

2-Create a Spaceing Parameter Between the Seats.

3- Clean the Length Formula and then Create the Round Formula For Number Array:

 roundup(Length / Spaceing)
