Derived Sketches - How does one......

[Aquatic]

mirror the entities?

I need to place a derived sketch(sketch 2) on the highlighted face at the bottom. But when I do it the sketch ends up in free space 180° out of position.

In the "Lombard Bible" it says "you can change the position and orientation"
Is it possible to mirror the derived sketch?

Cheers

Just use RELATIONS is petty simple...

start at one end and make a coincident relation etc..

I'm obviously too simple.
There absolutely no way to get this right. As soon as you add the 3rd relation it over defines the sketch without bringing it into the correct position

[suzukirmz]

use one collinear and one coincident.... not two coincident


this can not go wrong

Still not winning.

This is what I have done, please could you advise on my errors

I have a 5 blade item that has pockets on each blade. The pockets for each blade are not the same, but very similar and related.
I have put all 5 sketches on blade 1 so that I can constrain them in relation to sketch 1 and any modifications and transfered to all the sketches.
From there I use derived sketches to transfer the appropriate sketch to corresponding blade Blades 2, 3 & 5 work, no problem.
But on blade 4 the derived sketch is mirrored and in open space between blades 1 & 2.

I have added screen captures of the sequence

next 5

I am getting extremely frustrated with this.

please ignore the right side of the pictures. that is my dual screen setup running mspaint making the pics

just make a mirror of your base sketch and use that for derived sketch

Thanks suzukirmz

I was hoping that this wasn't the solution. Just makes the whole part a bit messy. My limited experience with SW is that most things work pretty easy. this one of those things that doesn't.

To follow on from this now:All suggestions appreciated

I need to make Ø19mm x 11mm deep pockets at each of the circles. The thing is they are not flat to the face but at 12° and the orientation follows the curve around the corner. So the pocket closest to the body is 12° facing forward along the body and the last pocket's orientation is perpendicular to the first pocket. 12° @ 90° to the body.

How do I keep this operation as simple as possible?

Thanks in advance
