I am trying to design a bicycle wheel. Initially, I've created a plane just above the tyre surface and sketched the design of the threading. Next, i have created another sketch on tyre and applied revolve feature so that the surface acts as reference for the cut extend feature to apply "upto next" option for threading sketch to project and cut upto the reference surface . But when i try to circular pattern this cut-extrude feature, it shows "geometry pattern fails". Couldn't figure out what possibly I could have done wrong. I am kind of beginner in cad designing...so i'd be very grateful if you could help. Thanks in advance.
using "upto next" under Extrude cut Feature is the root cause of the Problem. Patterned feature can not find the "upto next" reference you used in first extution therefore Shows the error "geometry pattern fails".
using 'Blind' Option and you will be all right.
Extruding the sketch directly won't help because tyre contour is not a plain horizontal..so it must be projected to get threading right...anyway i have attached part file..feel free 2 have a look
I sometimes try differently (although not so nice way). In your case, instead of 'extruded cut' try 'extruded Boss' the master pattern (without merging it with tyre). Then pattern the solid master pattern around the tyre. Finally use substract Option under 'combine' Feature to substract all the patterned solid from the tyre.
maybe you can upload the file (if it's not sensitive data) here so that I can have a look.
Sahedul Abedin, thank you 4 responding. I've initially tried that. but as the design is on a horizontal plane, it isn't getting projected onto the surface. Instead it cuts upto the distance we input. I need the threading upto a depth of 2mm. For this reason i've created before mentioned surface inside tyre. I've attached images to question showing the usage of blind option. Have a look.
Try extrude cut from the surface and then use blind direction.
