AutoCAD Based Calculations (Ribbon/Toolbar/Location)

Button: Start Autocalcs Function: Finish Area


AutoCALC is creating extra node points where there shouldn't be.  In the image below, node 45 shouldn't be created as there's neither a flowing head nor a change in diameter at that point.


'extra node'

'extra ref point'

'extra reference point'




Unknown but related to the flowing head markers (block OPHEAD)


Return to the drawing then;

a) Use the EBB command to erase all the flowing head markers (OPHEAD).

b) Delete all the white nodes using the DL command (HYD2 layer)

c) Type in ERASEX<enter> to start the hcad_erasexdata command

d) Draw a new rectangle for the remote area, delete the old one

e) re-insert your flowing head markers for the area in question.

Then re-run your autocalc.  You should be all set.
