How do I mirror this selection (in x axis) so I can select the other side (same vertices assuming my mesh is symmetric) I just want to select the other side not do any operations.
Choose Mirror from the Select menu and check the Extend option.
- Go to edit mode
- Go under the modifiers tab and add modifier. Look for the Mirror option under generate.
- Ensure that the X-axis is checked. Click on the vertices buttons under the Mirror modifier and you should be able to see it in your 3D view.
- To apply the mirrored vertices click Apply.
