thank you
that now brings its own set of complications to all the other parts, perhaps I will have to make the legs unique to each other so I can widen all the legs outwards.
Bt the way your example shows to use the move tool, is that doing the same job as push/pull ?
Flip the other legs to orientate them so that face is facing out.
Push/pull will work on a single face but move will work on multiple faces.
So if the leg was curved you could select all the faces of the curve and move them 15mm.
Thanks again, thats interesting about move compared to push/pull
As another example of the difference, using move you can select an entire end of a part, including structure such as dovetails, pins, tenons, or motises, and move the entire suite to alter the length of the part. I do so fairly frequently when I change my mind about the best size for a piece. You can’t do that with push-pull.
Edit: I also frequently move a copy of the end across to the opposite side of the piece, flip it, and put it in place there. Much faster than drawing it a second time and, at least to me, less effort than making a half piece, flipping a copy and then deleting the edges where they join.
Look at the my version of your project. You will see that I set it up so you can do things like changing the width of the legs and modify the length of the rails easily without redrawing anything.
I did a Design. Click. Build. Blog post not too far back that demonstrates this.
I opened the file you did for me Dave but to be honest I don’t see how it is set up, all I see is 2 tool stands that both look the same to me. Should I have dimensions set to show or something else Im missing ?
I shoved your model to the back down the green axis and redrew the model at the origin. Go to Window>Model Info>Components and tick the box for Show Axes. Then you can see how the components are flipped to make mirrored instances.
I understand the concept of flipping components ( I’m sure I saw it on one of your videos) but i don’t actually see anything in the drawing to indicate it. I see a couple of small axis marks in different parts of the model but thats all. I think I should go and watch some tutorials on using the axis
You really should start asking questions in specific threads with relevant titles, but I guess this one wasn’t really a question just a wandering thought.
However, you need to get a handle on how flipped components work, it’s pretty straightforward, look at the direction of the three axis colours at the origin of the component.
You can turn them by going Window/Model info/Components/Show Component Axes.
Here I have done a right angle to make it a little more obvious, by flipping the component along the red axis the push/pull will bring the ends together. If I move the copy the other way it would move the ends apart. and so on and so forth.
So think about a simple square table leg, which way do you need to flip each component to make the relevant faces P/P in the right direction.
I understand about forum threads, I will stick to them in the future, I guess I just kept this going as a conversation 
That is a terrific example of axis ( axis’s, axes), its clear now to see what DaveR was talking about. I just needed a more basic example ( which you have done)
Thanks again
