[DTM site modifier errors]

i simplified my life by tracing the footprint of the basement, extruding the poly, and then subtracting the extrude from the site model. good enough!

thanks for all the suggestions!

[DTM site modifier errors]

i've tried regenerating the site model from my existing data, but as soon as i put the site modifiers in i get the same error message of a pad intersecting a fence. i tried removing all but one pad and the fence but again--error...i tried starting with a new pad and a big fence around it, but nothing changed when i hit update.

maybe i am not using the site modifiers properly?

i am trying to excavate a basement by drawing a pad and putting it at the proper elevation for the basement floor(which is 8' below the lowest contour elevation on my site model--is this a problem?

is there a better way to show a basement excavation so that when i show the architectural model the light wells don't look like they are filled in?

i was also trying to use pads to define the different elevations of the garage floor, the main floor of the house, and the courtyard.

in the site model layer i am working on, i have only the regenerated site model, four pads at different elevations, and one fence surrounding all the pads (with no visible overlapping). i don't have a nurbs road or any plugins.

there are no pads intersecting and

no plugins on the site model layer.

i use VW 12.

nocholas-i'd like to avoid redoing the site model completely--you said you regenerated your site model with the same data, can you elaborate?

i first generated my site model by importing the surveyor's plan as an image file i had scanned, traced the contours with polylines, converted the polylines to 3D contours then created the site model. i remember a pop up window asking if i wanted to keep the original data in the source layer (or something like that), but i think i chose no. do i need to start over from the point where i traced the contour lines with polys? do i need to redraw the site modifiers too?

thanks!!

any other suggestions would be greatly appreciated!

[DTM site modifier errors]

i have been working on a DTM with some frustration b/c each time i try to update my site model to reflect the site modifiers i have drawn, it gives me this error message:

"pad intersecting a fence"

but i have inspected my pads & fence very closely and can not find any intersection!

i have several pads at different elevations drawn within one fence--is this a problem?

one of the pads is for the basement so it's elevation is far below the lowest contour--maybe there is a better way to show excavation of the basement on a site model?
