Hi- Question: Can I add a cylinder to an existing cylinder. When I draw a circle to an existing cylinder the circle does not form to the shape. See the attached image. I’m currently using SketchUp Pro 2016 Thanks [image]I’m using SketchUp Pro 2016.

A circle is a planar object that will never conform to the curved side of a cylinder. But if what you really want is a second cylinder sprouting from the side of the first, do this: draw the circle as per your figure push-pull it away from the first cylinder to form the second cylinder move the n…

Here is a quick GIF of what @slbaumgartner explained (I am a visual learner) [image] The only thing missing is deleting the additional geometry on the inside of the pipe.

Aron- After I compete this action I cannot push/pull the circle. Alert: Can’t push/pull on curved or smoothed surfaces.

That is correct. These steps will give you a circle on the side of a cylinder. Once there, it cannot be push/pulled. I am assuming that you are looking for a different final geometry. Can you explain what you are hoping to create, then maybe I or someone else on the forum can let you know how to…

[image] Runslongtrail: After I compete this action I cannot push/pull the circle.Alert: Can’t push/pull on curved or smoothed surfaces. Correctly speaking, the shape on the side of your cylinder is not a “circle”. It is a 3D curved surface whereas a circle is planar. Pushpull extrudes a pla…

Thanks for everyones input and help. I think I’m rolling. Mark

thanks TheOnlyAaron it worked great for me

Aron- What view are you working in for this tutorial. When I draw a circle to the side of my cylinder it lies flat on the red axis. Thaanks

Can you post another screenshot? I’m not sure what you mean… I was in an isometric perspective view.

I’ll refer you back to my previous answer to this question.
