Yeah, symmetry in LDDP doesn't work great for primitives. I suggest to use MLCad for that.
First set your rotation point on world origin (settings > rotation point). Select everything you want to create mirror, copy/paste, then Edit > Move > Keyboard entry (or keboard icon in toolbar). There check "Use rotation matrix value". Transformation matrix is displayed as "1 0 0 0 1 0 0 0 1". Change the 1st "1" to -1 for a x mirror, 2nd for a y mirror, 3rd for a z mirror.
Note that if a single primitive is selected, you may see the absolute transformation matrix of the primitive instead of identity matrix "1 0 0 0 1 0 0 0 1". In this case just select another element that will be mirrored too... but it doesn't matter much if you select a comment line
