    Ambulance Design Grades

    Any good sources of design criteria (or suggestions) for grading a vehicular access for an ambulance at a medical center? I'm referring to the area where an ambulance would park while it unloads its patients and the manuvering area for the gurney. Maximum allowable grades?

    Acad Function to sum selected lines/arcs or plines.

    Is there a function (routine, lisp, etc.) that will add up the lengths of selected objects? For quantity calculations it would be nice to be able to select a group of lines/arcs or pline and have ACAD sum the lengths.

    Autocad 2004/Land Desk/Civil Design

    Utilizing Xclip on excessively large xreferences can reduce the processing time when regenerating your file. Pick a workable boundary on the xreference and clip to that boundary. It will speed things up if your reference files are the problem.

    HEC-2 Help

    It's been awhile, but from my past experience it was fairly common to improperly enter data using HEC2. (It sounds like your creating a "punch card" and running it through the program.) If you haven't used HEC2 much you might want to double-check your data entry; make sure your...
