Modelling - Creating Tripod Object I am trying to make a city landscape but I can't figure out how to make those fancy rocks on the beaches. I've tried multiple things but they don't seem to work out well. Any help would be appreciated. Thank you.

Edit - These are four conical sided rocks.
Here are some methods for a 4 studs shape:

First method (Boolean):


Create a cylinder (12 vertices), put its origin to its bottom.
Duplicate it with a shiftDenter.
Rotate the copy 120° (or whatever angle you need) on the Y axis.
Duplicate the second cylinder and rotate it 120° on the Z axis.
Again create a fourth cylinder and rotate it 120°.
Now use some Boolean modifiers to merge these 4 cylinder.
Remove doubles to make the final object clean. You should not have any vertices inside your mesh but if it happened just delete them.




Second method (non-Boolean):

1 - Create a cône of 3 vertices, Radius > 1, Depth > 1.5, it gives a 4 faces pyramid

2 - In Edit mode, select all the vertices, and bevel them with ctrl shift B

3 - Select the 4 hexagons of the shape

4 - Extrude the hexagons with alt E > Individual Faces

5 - You have a basic 4 studs shape

You can add a Subdivision Surface modifier, you can make each end round with W > Loop Tools > Circle, you can add Edge Loops, etc...



Third method (better non-Boolean):

1 - Create a cône of 3 vertices, Radius > 1, Depth > 1.5, it gives a 4 faces pyramid

2 - Subdivide each angle of the pyramid

3 - Select all the new vertices and scale up so that you have some kind of regular hexagons on each 4 faces of the shape

4 - Select all the faces and alt E > Extrude Individual

5 - Keep the end of each extrusion selected and W > Loop Tools > Circle

6 - You can add a Subdivision Surface modifier, can add Edge Loops, etc...
