Hi...i'm new to Solidworks.

I'm looking to design a circle extruded to a cylinder but divided into 8 parts.

The radius of the cylinder is 40mm and height is 8mm, and each division is going to be 45 degrees each.

How do i do that?

Thanks

You can do it many different ways. Let's start with 2 suggestions.

1. Extrude a 1/8th pie and perform a circular pattern of bodies
2. Extrude one full cylinder and split it in 8 pieces.

  Hi Alin,
  
  Thanks for replying. I did the extrusion of the 1/8th pie and performed a circular pattern but it gives me a warning.
  
  Here's what i mean.
  Thanks Alin Vargatu

    You haven't selected the anything for the axis of rotation, in this case you can simply use the edge. Also, pattern the body, if you pattern the feature you will end up with one solid disc.

      Hi @Erik
      
      I have just followed your instruction and i had these.
      
      But i would like to make the cylinder look split like the image below but into 8 divisions. So. i can select a part and check the coordinates of just that part. Would it be feasible to send a sldpart as well?
      
      Thanks a lot for replying @erik

        Onyekachukwu,
        You have the Boss-Extrude feature selected to pattern, you need to clear that and pattern the body. You have the option of patterning features and faces, or bodies, but not both in one pattern.

  Hi Alin
  
  I have also implemented the second procedure but it reads the sketch has a self intersecting contour.
  
  What could have gone wrong?
  
  Thanks

Correct Answer
Create the 4 planes (45 degrees) and use the Split feature (not Split line).

EDIT: You can create 3 planes actually because you can reuse the top plane.

  Jackie Yip thank you so much. I tried using this method to work on something similar but i have failed.
  
  Its a similar circle with 80mm diameter extruded to a height of 8mm but sliced into 14 parts such that it looks like the figure below.
  
  How do i go about that?
  
  Is it possible to send an sldpart as well.
  
  Thanks a lot.
