Autocad 3d modeling9/10/2023 ![]() ![]() ![]() Then I created the two large cylinders and subtracted them from the brush cylinders. Then I Mirrored it and Unioned both pieces together.įor the brush, I just created a bunch of cylinders and arranged them on the head. Then I put a Fillet radius around the bottom edge. The only tricky part was the transition piece connecting the head to the shaft.įor the shaft, I drew the profile and Revolved it.įor the head, I drew the outline and then extruded it up a little. It's all pretty straightforward modeling operations. do you have the actual toothbrush from which you can take rough measurements? Any command you can think of has been demonstrated by someone at one time or another. there are tons of AutoCAD videos on the Internet. Again, you will have to consult your book and/or the Help file to learn how to use this command. Once you have them in place they could be shaped (higher at each end and the middle) via the SLICE command. I would made one set of bristles, then copy them to create the rows which appear to have 2, 3 and 4 sets of bristles. The bristles can be created using the EXTRUDE or PUSHPULL command. This needs to be a smooth transition as you are going from a round shape (the handle) to a flat shape (the head). The tricky part is the point at which the head attaches to the handle. The portion of the toothbrush head that holds the bristles could be created using the LOFT or EXTRUDE command. The same command could be used to create the bulk of the handle above the truncated cone. I suggest you look at the instructions for the LOFT command both in your AutoCAD for Dummies book and in the AutoCAD Help file. For example, starting at the very bottom two circles, one larger than the other (the bottom) would be lofted to produce the required shape (a truncated cone). CADTutor) has indicated the use of the LOFT command would aid in the construction of your 3D model. Judging by the image I see that this is an attachment for an electric toothbrush. ![]() If I still had full AutoCAD on my computer I could probably walk you through it but doing it using just typed instructions would be a bit of a chore but here are some basic ideas. ![]()
