Yes, can be done, fairly easy.
Have not done in ages so don’t remember the tool name….check the user manual
Essentially you select the shape, hit the tool for mirror, pick the plane you wish to mirror across, and the distance.
Do it last after one whole side is done because from then on everything you do on one side repeats on mirror copy…but if you break the link then it no longer works that way and hard to get it back.
If you wish to make half an object, mirror distance set near zero, then select all points along that plane of both object halves, then weld together and you have one whole object.
