Inserting knurl feature on cylindrical surfaces

Pattern a helical sweep cut.

Then do another one in the opposite direction.

But only if you really really have to.

" But only if you really really have to."

Indeed. Much better to use texture mapping to put a picture of a knurled surface on your model. Actually modelling it is a waste of time and savages graphics performance.

Or create a cosmetic thread and detail it as a knurl on the drawing

: Or create a cosmetic thread and detail it as a knurl on the drawing : Good suggestion, only a cosmetic thread creates a dashed representation of a thread surface in drawing views. Once again, PTC, for the hundred millionth time, we need a COSMETIC KNURL!! It would take input on type (straight, angled, diamond), pitch, tooth depth and, then, in the model, show lines indicating knurl crest or root and in a drawing view, present a note containing the basic knurl information. This just can't be that difficult.

I totally agree David! Since Pro/E falls into the MCAD category, you would think that it would have superb knurling functionality. Especially when you consider the number of years that the application has been in existence.

This has come up several times recently, any other ays? Any nays? Pete, Dammerl, Chris, Dakeb, meld_b, Gwilym, Shankar, Martin, Mike, Dave, Kenny, other regulars?

Sort of like a cross between textures (which don't show up on drawings) and cosmetic features, I'd like to be able to simply apply a cross-hatch to the knurled surface in two directions, and define the spacing/angle. This would look good in the elevations on the drawing. It would probably be listed in the cosmetic feature menu.

I am not sure about ANSI or any other national standards, but in the German standard (DIN) there is the possibility to display the knurl as a partial x-section. Basically in drawing mode, you draw a closed loop around your cylinder and fill that with a x-section according to the type of knurl. Just a workaround and takes some time, but you get your display properly to the standards. Add the according note and you are all set.

I guess in part mode, a texture is the best way. Cosmetics other then threads have the disadvantage that they shine through the part from the back-side. Modeling only if you need more time while zooming and other display operations (for coffee and such).

I'd sure love to have that. While we are making up a wish list, how about modifying the Hole Wizard to allow simultaneous creation of multiple holes of the same type and size (one of very few features which are IMO much better in SolidWorks: you put points at future hole locations, select the hole type and size, and voila! you are done). Also, get rid of the 3D note the ProE Hole Wizard creates and make a set of parameters created with a hole more flexible to allow people to tailor drawing hole callouts to their company standards.
