Non stretchy doors

[Anonymous]

Hi
I'm doing a door object for calculation purpose.
My q is:
How can I do non-stretchy (fixed) doors where users are disabled to use the A value?

The approach will depend on the door(s) you are using. At the beginning of the Master Script you could add a line:
A=2'-6"
which would set A to the prescribed size and ignore the user's input (so you should probably add a Lock statement for A so the user realizes that they cannot change A).

Hi David
This was my first idea as well but....
the thing is that I want 4-6 different predefined (fixed) sizes of doors.

If modul = `M7` then A= .7
If modul = `M8` then A= .8
an so on.

another thing is that even the A is locked (Lock "A") the user is still able to stretch the doorhole graphically which is not the intention.
Is Wallhole2 the answer?

You can lock the value of A by using values lists.
1. Set a list of values for modul in the parameters script
values "modul" "M7", "M8", "M9"
2. Define values lists for A depending on which value is selected.
if modul = "M7" then values "A" 0.700
if modul = "M8" then values "A" 0.800
if modul = "M9" then values "A" 0.900
That's enough to set and lock the parameters in one shot.

Thanks a lot - it works
Why is it we need the " " with the "A" value?

While Andrew may have a more technical description, the quotes are necessary around the "A" because that is the variable being affected by the VALUES statement. The syntax is VALUES "variable" possible_value_1, possible_value_2,...possible_value_n. Furthermore, if the possible values are strings rather than numeric, they to would be in quotes.
