Is there way maintain as one line or surface even when they are exploded?

“When a line or surface is mirrored, two lines or surfaces become one when they are joined. Is there a way to maintain them as one line or surface even when they are exploded ?” .

Unless you run SimplifyCrv on the joined lines, if you Explode the resulting polyline, it should go back to 2 separate line segments.

Similarly, unless the joined surfaces are coplanar and you run MergeAllCoplanarFaces on them, if you Explode the polysurface after joining it should re-separate into the individual surfaces.

It’s working well, Thak you very much ^*^
