I'm wondering if I'm missing something in terms of the control we have over site modelling in Vectorworks. I've attached a screengrab of a site model I have created. Blue lines are the 3D polyline contours I have drawn and set to 0.5m height intervals, the green lines are the contour lines generated by the site model calculation by Vectorworks, using my blue lines as input data. I have two big issues with this output, namely: I want the model to EVENLY interpolate between the contour lines - for example on the hill to the bottom of the screen grab, I want the mounding to extend evenly to the left, I don't want flat platforms between each level. I want the contours to actually follow the curves I have drawn, and not truncate my contours in large angular lines!! (As seen in the middle of the screengrab.) Is there anything I can do, aside from draw contours at really tight intervals to reduce the visibility of the problem? Is this just how the site modelling algorithm works? I understand the need for a mathematical algorithm, but this results in a fundamentally incorrect site model I can't really use for anything in terms of BIM or production information, as it isn't giving me smooth grades. I'm sure I could fudge it for visualisation purposes, but I need an accurate technical model I can issue in IFC form to provide information for collaboration and also construction. I've turned on mesh smoothing in document properties, which makes the rendered model appear slightly less angular, and also turned on contour smoothing display, but I need an accurate model in terms of BIM compliance and I'm not sure I have this control outwith doing an excessive amount of contour drawing. Is Vectorworks the wrong software for this, or am I missing something? Any ideas or advice would be much appreciated. Lisa
