Can someone give me tips on how to create this feature and what it's called. It's built on radial feature. Most hemostats have them.
I don't know what it is really called, but I would call it a ratchet.
To make a nice, clean tooth, I would put a plane at the bottom of where you want to add the teeth. Draw radial lines running to the center pivot of the handles to represent the bottom of one tooth. If you are really fussy, put in a construction line midway between the two lines. Put a plane perpendicular to the end of the construction line. Draw your tooth profile on that plane, adding Pierce relations between the two bottom end points and the lines in your first sketch. Sweep the profile with the two lines in the first sketch as path and guide line. Trim the beginning and end with a drafted cut using arcs in a sketch on the first plane. Circular pattern the tooth around the center pivot.
Thanks. I've never used the pierce relations. I'm also using 2003. Will it work with that version.
Should work in 2003.
I created three sketches
Then I get stuck by not knowing which steps to take to create the sweep.
Any additional tips will help.
If you're doing it as a sweep and I'm reading Jerry's instructions correctly, then you will need to make a couple of changes to your sketches. The sketch that's vertical is giong to be your sweep profile but first, you'll need to make that vertical line construction geometry. A sweep profile in 2003 can only have a single closed loop.
The sketch that's laying flat is going to define your sweep paths and guide curves. But in 2003, you can only have one guide curve per sketch. So create a new sketch on that same ground plane, use convert entities to clone the left leg of that triangle, then make a new sketch and clone the center line and a new sketch, cloning the right line.
The next thing you do is create your sweep. Select your vertical triangle as the path. Select the center line on your ground triangle as the path. Change the profile orientation to 'Keep Normal Constant'. Then, in the guide curves box, select the left and right lights of your gorund profile. The preview should look like a shard of glass if everything works right. Click OK and you've got the first of your four teeth. Use an array to make copies of the teeth in a circular orientation.
It's probably a good idea to build the base of the hemostadts under your tooth before you pattern it. I know 2003 supports multi-body modeling, but I don't remember how well it implements it and I'm sure it doesn't have a combine fetaure, so you'll have to build this using a single-body methodology.
I also put together a quick video showing an alternate construction technique. I use 2013, so the dialogs will look a little bit different, but all of the functions I'm using are in 2013.
Thanks for taking over the thread and helping Mike out. (The day job got in the way yesterday, so I had no time for the forums.) Good explanation, and then a bonus video to boot!
