Why there is a bad display with /ESHAPE,1 command with nodes initially coincident and have different

  This is a limitation of /ESHAPE and PowerGraphics. /ESHAPE,0.99 is the correct workaround. From /ESHAPE: When nodes are initially coincident and PowerGraphics is active, duplicate polygons are eliminated to conserve display time and disk space. The command may degrade the image if initially coincident nodes have different displacements. The tolerance for determining coincidence is 1E-9 times the model’s bounding box diagonal. Since the tolerance in 1e-9, you can shrink as little as /ESHAPE,0.99999999.
