Copying, pasting or mirror certain section

I have this cylindrical port on one side of the cylinder head and i need to flip it onto the other side to align with the other ports (pill shaped on opposite side of cylinder, not extruded and cut yet), not sure how to do that exactly.

Your file should be following a methodology that allows you to first Mirror the manifold body on the left, and then without joining, reposition the new manifold with a Joint.  (However, the left manifold is one piece with the barrels)

Once both manifolds were constructed, they are then Combine Joined onto the barrels.

Be aware that blue sketch articles are not stable, and fully constrained sketches are recommended, for accurate updating.

If you are repeating work like this - you can make things easier by using techniques for Fusion to do the extra work for you.

Also, shouldn't the Block and the Cylinder Liners be separate components - just like the real world?

Would you be willing to start over with step-by-step instruction on more efficient techniques?

im not sure what the blue sketches are that you are referring too. does this mean if it were machined some measurements would turn out to be incorrect?

[jude_a_williams4]

i think i understand what your saying, but not 100% sure. The block and cylinder liners are one because eventually i was going to cut cooling fins up to the outside of the cylinder walls, as this is designed for a vw type 1 air cooled engine. I could start over and learn more efficient techniques. If i were to cut the cylindrical port in half would this be machinable by cnc?

oh so the red lock sketches just prevent sketch lines from accidentally moving or being resized?

And gives you complete robust and predictable control over your work.

hello, can you check this sketch? I think it looks better. If i am planning on this fitting with very little clearance do i design it into the sketch (for example i have one circle at 90mm and another at 90.025), or do the people machine/cnc shop take care of the clearances and all i have to sketch is the perfect fits without clearances? Thanks

Much better, however can be more efficiently done, if you decide mirror in the modelling window.   

Based on other questions you have asked, this appears to be a "Layout Sketch" for the barrels, pistons, head and Bolts?  Not sure.

This means consideration of Rule #1 with some of this sketch in those Component's inputs.  Early stages now, but end result should be driving the inputs.

Does this help?

Clearances - you need to develope a strategy for all your modelling,

places where you decide how to make pistons with clearance in a barrel, cylinder sleeves in a block, bolts in bolt holes, there is no right or wrong answer.
