i used clone single command to clone an object ...... it worked perfect and also when i edit the original mesh the cloned mesh also updates real time.....but the vertices located at the middle line doesen't seem to be welded ..... can we make them welded and begin our process or is it ok to keep it as it and after finishing our model & just weld it ? ......thanx
