Dynamic Mirror - A really quick tip for instantly creating symmetry within a sketch in SOLIDWORKS.
1. Draw a centreline, ideally going through the origin
2. Within the active sketch, select Tools > Sketch Tools > Dynamic Mirror
3. Select your centreline, two parallel lines should appear at either end of the centreline
4. As you create a sketch on one side of the centreline, the Dynamic Mirror tool will automatically create a symmetrical shape the other side, which has the same relations as the sketch you’re creating.
A simple tool but can save a lot of time especially on complex symmetrical sketches, give it a go!
