Help with a project
-
I am trying to design a component for a project. Sketchup should be able to handle this but as a newbie, I am not sure how to get it done.
I want to create a 2" diameter by 2" high cylinder that has two 3/8" intersecting "tubes" bisecting the cylinder from the curved edge. The angle between the two tubes is 60 degrees.
When complete, the cylinder will have 3/8" rods inserted into the four holes created on the edge of the cylinder. When viewed from the top, you will see a circle with four rods radiating from it in a narrow "X" pattern. The angle between the rods will be 60 degrees.
I would really appreciate it if someone would help me get started on this project. Creating the intersecting tubes has been a real challenge for me.
Thanks in advance.

What have you got so far? Making cylinders in SU is pretty straight forward. Do you need to show the thickness of the tubes as in the walls of a pipe? You use some terminology that may be confusing or may be indicating something more. I'll post a picture, since you do not, to see if it looks something like and everyone could take it from there.
This is a thin wall version.

This is exactly what I need. Where can I find a tutorial on how to make this? Could you attach the actual file so I can do some further modifications?
Thanks,
Bob

Nothing special to Do!
So you have a tube as Volume
Make any tubes you want at any dimensions and positionsIf you have the Pro version you can make a boolean operation (Intersection...)
else Intersect your tubes and erase by hand the no wanted volumes! -
As per Pilou, draw the circles you want. Note that when you draw them (by entering "(integer)s" or aftewards, in the entity box you can change the number of sides. Use Push pull to pull them up. You pull out the radius, click, then type in the proper radius.
For the horizontal tubes move your view so you are looking at the horizont, choose circle tool. hold it up in the "sky" till you get a red or green circle. hold shift and draw your circle. You can then pull a cylinder that is parallel to the x or y axis. Make it a component.
How to position? I would go to an overhead view and turn on hidden geometry. Move your small cylinder from the top edge up or down until you see z axis (blue) indication and press shift. Move up and down and align the top edge with the top of the fat cylinder (a component) (leave top face on the fat cylinder for now). Then with move tool hover on the top edge of the small cylinder and find the "Midpoint" of that edge. Click down move the cylinder to the top edge of the fat cylinder and hover, then move to the center of the top face of the fat cylinder to find "Center" inference. When the move snaps to that point let go or click. Similarly you can use the edges and points on the cylinders to snap / move the small cylinder down to the midpoint of the fat one.
Use the rotate tool (with option key down for duplicate)to rotate a second component at 60 deg. Get a blue protractor with the rotate tool then press shift. Hover on the top circle edge of the fat cylinder and then move to the center of the top surface to find the center. Then you can click down to establish center of rotation. No need for shift key then, but use option key and rotate a duplicate component at 60 deg.
What is this for. If only for a model or picture that will be viewed as-is. I would not explode the components or affect their geometry. I would not make holes in the cylinder. Instead I select the three components and context menus intersect with selected. this will give the appearance of holes by placing edges in the model. Group these edges for security.
If for some reason you need to make holes. You will have to work inside the components. Holes in the side of cylinders in SU can make messy geometry and also may not look smooth, depending on how many sides they have.
Main things are rotate and move. Learning to use inferences, and constraining movement on an axis.
