I have made some code to construct a part to be used in Eagle3D.

If the part where i create the pins is placed outside the macro that creates the
shell all goes fine.
But when i place it all inside the macro it complains that the closing bracket
for the object cant be found and it finds object instead.

union{
    difference {
        cylinder{<(breite/2) * -1,0,0><breite/2,0,0>(i_radius + dicke)}
        cylinder{<(breite/2 + 0.1) * -1,0,0><breite/2 + 0.1,0,0>i_radius}
        box{ <(breite/2 + 0.1) * -1,(i_radius + dicke + 0.1) * -1, 0>,
             <breite/2 + 0.1, (i_radius + dicke + 0.1), (i_radius + dicke +

Maybe my use of object/union/difference is faulty but i cant see it.
Its sometimes not logical i think but maybe i am not thinking locical.
p.s. It looks that i am the only one using this newsgroup
