Library object inclusion with CALL command?

Anonymous — Thu, 08 May 2008 08:27:59 GMT

Dear GDLers,

I have created my first HelloGDL parametric table. However, instead of the BLOCKs I used as chairs (that are parametrically laid out around the table) I would like to use one of the many chairs from the built in library.

I could certainly copy the Script from the chair in mind from the library into my script and call a subroutine or s.th. but I am convinced there is a more ellegant way than this.

I guess the CALL command is a potential candidate, but I could not figure out how to use it properly .

I was not able to retrieve anything after browsing the docs.

Has somebody a small example for me?

Thanks a lot in advance
Jakob

Hello,

Just make new (length) parameters in the main object;
leg_x_dim
leg_y_dim
leg_z_dim

and the main object's 3D-code;

!--calling lower left leg
add -a/2+ leg_x_dim/2, -b/2+leg_y_dim, 0
call 'legmacro' parameters a=leg_x_dim, b=leg_y_dim, zzyzx=leg_z_dim
del 1

!--calling lower right leg
add a/2- leg_x_dim/2, -b/2+leg_y_dim, 0
call 'legmacro' parameters a=leg_x_dim, b=leg_y_dim, zzyzx=leg_z_dim
del 1

In the 'legmacro.gsm' you have 3D-code;

add -a/2, -b/2, 0 !<--movement to centralize the leg
block a, b, zzyzx
del 1

!--the leg dimensions can be hard coded too -> so no need to make parameters 'leg_x_dim' , etc.

call 'legmacro' parameters a=0.03, b= 0.04, zzyzx=0.7

The point here is to have parameters of same name and type when transferring data; here A, B, ZZYZX.

You could also;

call 'legmacro' parameters

In this case the leg has the macro's default dimensions.

Hope this helps.
