I need to draw a plate which is the surface will match the contour.the picture below shows a plate. noemal to the bone. Any one can suggest how does it can be realized. Thank you
I'm afraid I don't really understand what you want to do. Do you want to make a plane that is tangent to the bone at a particular point?
If so, use Features/Reference Geometry/Plane. Pick the surface that you want to be tangent to as the First Reference. Pick the point that you want to be tangent at for the Second Reference.
Thank You Jerry,
Actually i wanna make the plate as in picture I post and make the surface to follow bone contour
You could try a technique like I used in the attached file. I copied part of the surface of the femur with the Surface Offset tool (with 0 offset), then trimmed it with a sketch, then thicken the surface. However depending on what parts of the surface you encompass with the plate it might have trouble doing the thicken feature. If that happens other people might have suggestions on how to resolve it but I don't have much experience with surfacing.
how to trim the surface with a sketch..it is in different entity?
Trimming a surface is just like Cutting a solid. Edit the part with the surface in it. Use an exixting plane or, if necessary, make a plane in the right orientation, to put the sketch on. Make a sketch with the proper outline. Pick the Trim feature in the Surfacing Toolbar or Insert/Surface/Trim.
In addition to Jerry's advice, make sure to use the "Manual" option when trimming.
Thank you, I manage to trim but when I used thicken command, I got an error like in atachment file ( failed to offset or face could not be deleted)
That usually means that your offset thickness is greater than the minimum radius of curvature. You can probably use the Curvature Display to find the face or area that is causing the problem. You can then Offset the rest of the faces and the patch the missing area, probably with a Fill Surface. Then use a Boundary Surface or a Fill Surface to add the sides, Knit it together, if necessary, and Thicken, if necessary, to get a solid.
