DTM definition meaning 1 Z value for a pair of XY coordinates. Well, picture the face of a cliff, there may be several Z values for one XY coordinate. So I want to make a mesh or build a surface not confined to a projection. I can do this in other software but I am not sure how to create this within Bentley OpenSite products. I have Open Roads InRoads and my client uses the civil packages for design. Any help would be appreciated.</p> <p>Thank you!</p> <p>Fred</p><div style="clear:both;"></div>
