OpenScad not interactive modeler. Instead, it is similar to 3D compiler that reads a script file that describe the object and render 3D models from the script file. How OpenSCAD for Mac to export more parts of it from a script? Let us explain.

How OpenSCAD for Mac to export multiple part tutorial from a script
One way to generate them pile geometry derived from a single script as STL file without comments / annotation cancel code.
A variable PARTNO, for indicating the current operating member being exported. If PARTNO is 'undef', it is not exported anything.
PARTNO = undef; // default Part Number
module tree（）{
Color ( "green") of the cylinder (r1 = 12, r2 = 1, h = 30);
// ...
}
module trunk（）{
Color ( "Brown") of the cylinder (r = 3, h = 10);
// ...
}
module base（）{
color（“white”）translate（[ - 10，-10,0]）cube（[20,20,5]）;
// ...
}
if（PARTNO == 1）tree（）;
if（PARTNO == 2）trunk（）;
if（PARTNO == 3）base（）;
// 0 for the whole object can choose to use
if（PARTNO == 0）{
basis();
translate（[0,0,5]）trunk（）;
translate（[0,0,15]）tree（）;
}
An interactive work, PARTNO variable at the top of the file can be set from the GUI display / export number of components.
By writing shell scripts on Linux or MacOS or write a batch file on Windows, you can automatically export all components. shell script looks like this:
STL export to the part #
openscad -DPARTNO = 1 -o tree.stl model.scad
openscad -DPARTNO = 2 -o trunk.stl model.scad
openscad -DPARTNO = 3 -o base.stl model.scad
# Export images all combinations of parts
openscad -DPARTNO = 0 -o model.png model.scad
These are the answers to how OpenSCAD for Mac to export more than part of the problem from a script, I hope you can help.
