For the knitters out there, just ignore this post.
I'm posting this to my blog because it's information that I have to access every couple of months and I end up forgetting out I did that.
I found a good resource on how to convert your ESRI *.shp files to contours. I end up importing the lines only to find the line work is inserted at layer 0 - Can't make a surface from that! When I click on the line and look at the properties, the elevation info is contained within the database attached to the linework - GRRR! Note: I have to open a new drawing and import the SHP files from Map > Tools > Import - then save it and do the next stuff. I have not been able to define contours from large data sets of SHP files via the Data attachment with Task Pane. Anyone know?
But the next step is where I have to look up time and again - which takes about an hour to find each time.
Attach the contour dwg you just imported your contours into into your main dwg.
- Define Query of attached dwg
a. Location (usually All)
b. Query Mode (Draw)
c. Alter Properties
- now, click Expression - navigate to Object Data
- Hit "Add" button - do this for each data set. Then Hit OK
- Hit "Execute Query"
When you are building the surface, add them as Contour Data.
