First of all thánks very much for your very usefull hacked version of the C3DPipeRules.dvb. But i found out that there is still a bug in the original and your version if you work with rectangular pipes which have a différnt value for width and height. The problem are always the line in the code like: oPipe.EndPoint.Z = (dNewPipeZ + oPipe.InnerDiameterOrWidth * 0.5) or oPipe.EndPoint.Z = (dNewPipeZ + oPipe.OuterDiameterOrWidth * 0.5) This statement is fine for circular pipes but i found out, that it gives you the wrong cover if you apply the slope and cover rule for rectangular pipes, e.g Communication duct with a width of 2.06m and a height of 1.30m. According my tests if would be better to use instead the following property oPipe.EndPoint.Z = (dNewPipeZ + oPipe.InnerHeight * 0.5) or oPipe.EndPoint.Z = (dNewPipeZ + oPipe.OuterHeight * 0.5) If you find my remarks usefull maybe you can blog them to all users. Kind Regards Peter Bartel Hi Christopher,

It does not go through and change any values until the rules are reapplied. Running the macro manually won\'t do anything productive; it needs to be run through the normal Civil 3D pipe commands that apply the rules. In the pipe properties make sure the pipe has the cover and slope rule as a criteria. Scott Kent gave a good presentation last year at AU that explained how the rules work (http://au.autodesk.com/sessions/detail/444/). The modification in the above post only affects how the cover and slope rule is applied when no surface is present. It sets the elevation to a user prompted elevation instead of 0 in the default rule. If you want to know how to change the "C3DPiperules.xml" check out my class at AU this year (http://au.autodesk.com/sessions/detail/830/). The handout should be posted this week or next.

The only rule that seems to run for me is the "Cover Only" rule. If I open a new session and apply the "Cover and Slope" rule to pipes it doesn't even load the macro. I can load the macro manually but it still seems you need to run it from "Apply Rules.." under the "Pipes" pull-down. All attempts run the macro manually have been unsuccessful. Any input you can provide is greatly appreciated! Mark Spatz, E.I.T. C3D 2008, SP2 Does the “C3DPiperules.xml” need to be fixed as well?

If I use "Cover Only" it seems to work. Does anyone have a working "C3DPipeRules.dvb" they could send?

The manholes are at proper elevation, but the pipes are not. Is this what you mean when you say, "after you have worked with a pipe (working with a pipe should load the C3DPipeRules.dvb file automatically)"? I would really like to see this address my problem, cause I figure it will be the 2010 release before we see Intellisolve integrated into Civil 3d. Thanks, John Cobb, LA Lexington, KY Christopher,
