Hey all:
I have a .dgn file that contains a mixture of 2D lines and 2D smartlines that represent the proposed contours. What is the best procedure to convert these for using in creating a DTM?
Using Geopak Eng Suite V8i.
Thanks!
When I do the proposed contours for parking lots, I prefere to use lines for the proposed contours since the parking lots vary so much and for the many changes that will come. After I've created the proposed DTM is there anyway to make the parking lot an object in a model so that I can do the side slopes, ponds and roads by objects in the same model?

Hi Greg,
I'll tentaively answer YES.
Once you build the TIN from your graphical elements (as discussed earlier in this thread), you can import that as an Object into Modeler.
Then:
1) Create a new Object (type Parking Lot would make sense).
2) Drape the graphical elements that make up your Parking Lot onto that Object that was created by importing the TIN.
3) Now your PL Object has the graphical elements and it should merge in your Site Project so you can do the other Objects (ponds, buildings, roads etc).
This does seem a more difficult way to do things. I'd typically suggest you design the Parking Lot inside Modeler as well as the other objects. While I've always found grading linear elements using the Site Modeler tools the most efficient way to design Parking Lots, you can still use contours if thats the way you want to design... Just add the contours within Modeler to the PL object.
Does this help?
Yes that helps!
Some questions on the Tolerance setting:
If a spot elevation is within 0.75 master units of a longitudinal reference, the software projects the spot onto the reference (perpendicular) element and uses the elevation to interpolate.
does this mean that the text must be within 0.75 (or whatever the setting is) perpendicular to anypoint on the line?
2. from help:
Spot elevations can be represented by graphical elements or text. For each MicroStation longitudinal reference element, GEOPAK locates the spot elevations nearest to and on either side of the element endpoint. Then, the elevation at the element endpoint is calculated. For example, the example shown below calculates an interpolated elevation of 137.57 from elevations located 10 meters and 25 meters on either side of the element endpoint
what is this talking about? Is the text assigned to the longitudinal reference to the nearest perpendicular or to the nearest endpoint?
