Rotating a sketch / other way to do this,

eric_carlstrom

Hello!
Here's a pic of my sketch =


My idea is to have that circle & arc combo that I have up top also at those yellow circles. The problem is that since the constraints on the arc are horizontal, it doesn't translate to the angles versions on the sides.
Is there a better way to do the arc bit or could I rotate my sketch so that all 3 sections all use their own local horizontal constraints somehow?

I appreciate any and all help! 

Cheers.
Eric

Given a choice, I most of the time would rather do a feature patten, rather than a sketch pattern

By the way, in the manner that I did the extrudes, if you try and boolean those three inner cylinders with the outer part, you’re going to run into problems.

So you could either do a composite or there’s other solutions, such as doing an overlap of the inner cylindrical parts with the outer shell, or separating the cylinders from the shell. Or you could extrude the little wings up to the same elevation as the top of the cylinders and that’ll take care of it

Added a second booleaned part studio

Do it the way Steve showed.

Why didn't you draw your part on the default planes?

Thanks Steve!
I apologize for the late response, but I've been swamped and unable to work on this. Looking at your sketch I instantly wanted to slap the past me. It really was not a difficult problem, even for me as a beginner but I must of gotten trapped in a box of my own making which made me unable to see this solution.
I really appreciate the help and effort.

Cheers!

Happens to a lot of us

Seems like I’m trying to punch my way out of wet paper bags more often than not at times
