    cut on curveture surface

    John Smith

      Hi

      I am trying to draw a tyre I almost finish everything, but the only problem I faced is to make the hrizontal pattern on the top of the tyre surface.

      I draw the shape and made ( project cuve on the face) then tried to cut the face, but no luck.

       

      any suggestions ?

       

      many thanks

      John

          John, it might be easy for someone to look at your files or picture of what you trying to do and finally suggest you something. Since there are more ways to skin a cat the solution might be different based on the real condition.

            Hei'ya John, here's a sample of one file,

            l posted this in another thread somewhere,

            well here it is again, use the roll back bar

            and edit feature to see the work flow

            hope this helps- have a good'n kelef

                Hi Kelef...

                Thank you for your reply.

                I changed the revolved surface with revolved boss as you did with your sample file, but still can't do the cut.

                could you please check the attached file and tell me what is exactly wrong with it ?

                 

                 

                manu thanks

                    Hei'ya John, try this and reset the options as required,

                    your sketch needs to be checked in the original,

                    it was self intersecting(had dangling geometry)

                    hope this helps- have a good'n kelef

                        hi Kelef...

                        first of all, thank you for what you have done.

                        but, could you please tell me in more details what was my mistake ?

                         

                        Many thanks

                            Hei John, glad to have helped dude,

                            if you go to edit your sketch for the profile cut,

                            and right click on one of the contour lines,

                            and from the menu "select chain", zoom to selection,

                            and you will see that you have what is called dangling geometry,

                            in this case specifically- self intersecting*

                             

                            dangling geometry.png

                             

                            l just trimmed the obvious over-run, reposition to coincident with

                            the previous channel form- confirmed

                            and then used the model to pick the different from/to

                            so that any model changes they would update and not fail

                            due to dimensions or missing geometry

                             

                            trimmed.png

                             

                            the feature circular pattern l used the tyre edge,

                            but any concentric element would do,

                            best tempory axis, wheel origin or if needed produce

                            an axis as required

                            hope this makes sense- have a good'n kelef
