Mirror Function in Modeling I am a beginner with Blender, I have the newest version of 2.9. I have been successful using mirroring in sculpting mode. However, I cannot get mirroring to work fully in low-poly modelling. It works with grab, extrude and scale tools, but not with others, such as loop-cut or poly-build tools. Is it something I am doing wrong, or the software currently doesn't support it?
For example, in the screenshot shown, I have made the extrusions from the cube successfully with the help of mirroring on Y axis turned on, and now trying to use loop-cut tool. But it does not repeat my loops on the other side.
I don’t know if this function is in sculpting, but it is in the mirror modifier! In blender 2.79 in the modifier is a mirror, in the settings there is a function &quot;Adjust edit cage to modifier result&quot;

Enable all functions in the modifier window, and try different actions, watching your model!
