    Scale Conversion of 3D Objects

    I am seeking to expand our use of 3D Vectorworks into allowing my students to export 3D pieces of their stage designs into STL files for use in our 3D printer. From my understanding, the STL does not include whatever scale you have your layer in when you export the 3D object, or at least my version of Vectorworks does not include this information. For an example, I have created a 4'x8' platform, a structure which consists of a 3/4" thick lid, and structure members made of 1.5" x 3.5" materials. I have created this in 1:1 scale on my layer. If I were to change the layer scale, the objects will adjust to the new scale. When the objects are exported as an STL and imported into the slicing program, it appears the full 4' x 8'. Not entirely unexpected, as I am aware the layer scale is for configuration within Vectorworks, and the actual size of the object is not converted. So, what I'm wondering is if there is a convenient shortcut method within Vectorworks to convert the scale of the object to a desired scale, typically 1/2" or 1/4". This could be done manually using the Modify - Scale Objects. For my platform example, I can mentally convert 4' down to 1" for a 1/4" scale model, and enter the appropriate measurements in Scale By Distance. However, with more unusual measurements, this might be a bit more tricky. So, is there a command function that will allow you to select an object (or objects) and scale them down to a particular scale ratio? I'm probably missing something incredibly obvious, but if someone has a thought and/or direction I could try, it would be great. Thank you very much.
