Example: Modify node point B02 length from 3.00 ft to 5.00 ft, what will happen? which of the 4 intersections below will or will not be affected and why? Answer: Correct !!! the same as found on the previous WIKI page. Intersection between Segment D and E After making the modification, select Tools> Model Consistency Check Report> wait for the report to be displayed. Note the W726-35 warning: * * * W A R N I N G - MODEL * * * W726-34: Inconsistent coordinates were reset at following point(s) D04 Now that the graphics have been reset, look again at the AutoPIPE model. Question, Why did this happen at this location and not somewhere else? Answer: Ah that is an easy one, Because of the model configuration with the segment directions. Detailed Answer: the node point modification was made on the input grid where it is automatically assumed that the "Apply offsets to all following points" option is enabled. If that is true, then all points downstream of B02 will be affected by an additional 2.00 ft offset in the +X-axis direction. Ok now from the image below, note the segment directions and keep in mind that the model is created based on Delta offset from the origin point progressing to the end of the segment. Using simple logic the following is determined: B02 moves 2.00 ft in the +X-axis direction Therefore the origin point for Segment C (B07) moves the same distance and direction. Since segment D has its own origin point but is connected to segment C at node point D04, the origin point for segment D is moved in the same direction and distance. Therefore, since the Origin point for segment E is D00, all the points on the segment E will move in the same direction and distance all but the connection point to Segment A, why? Because, the connection point is A03. A03 is drawn on a segment that occurs in order before segment B and the Origin point for segment B is A03. Therefore the modification at B02 does not get applied to A03 Hence the last node point on segment E, E01, is relocated based on the modified value and the connection from E01 to A03, is automatically calculated and connected. Thus the offset piping now exist between A03 and E01.
