Hi
I am having trouble trying to mirror a part, and I am hoping someone can help me.
I have drawn a part, with various holes and extrusions etc, and this makes up a right hand side plate of the mechanism I am drawing. I now want to make a mirror image copy of this part to make up the left hand side plate. How can I do this?
Regards

Use the Scale function. Feature>Scale...then set one of the axis to -1. (negative one)

I ALSO HAD PROBLEMS MIRRORING A PART, E-MAILED ALIBRE AND GOT THE SAME ANSWER. YES IT WORKED BUT I DON'T UNDERSTAND THE LOGIC OF USING A NEGATIVE ONE (1) TO ACCOMPLISH THIS. CAN ANYONE EXPLAIN THIS TO ME?
THANKS

Using a negative number for scaling one axis is the same as multiplying each coordinate for that axis in your original sketch by that negative number.

For example, if you had a square that was defined by these coordinates:

Point 1: 0,0
Point 2: 0,1
Point 3: 1,1
Point 4: 1,0

And used a scaling factor of X = -1 and Y = 1, your new sketch would have these coordinates:

Point 1: 0,0
Point 2: 0,1
Point 3: -1,1
Point 4: -1,0

In effect, the sketch is mirrored about the Y axis.

MAKES PERFECT SENSE

Just browsing this forum,
That -1 to mirror is a stone age way to perform a mirror,
This is a basic 12 parameter matrix command
I thought that new software was better than that

I agree...but it is what it is.
