No, this was all done in picoCAD; I've not delved into the import/export functions yet (I'm planning on familiarizing myself with other software like Blockbench, Crococtile3D (and maybe Blender at some point) sometime next year, though I have a little experience using/editing .obj files from my days modding Fallout4 using Nifskope) I found that the easiest way to create the tail was just to extrude the different segments all in one direction & then manually adjusted the angle of each part thereafter. Appreciated Ben!
