I’ve purchased adjacent tiles of contour lines. How can I connect all the lines end to end at the tile boundaries?
Copy the line work from one file, open the file for the adjacent tile and use the command “paste to original coordinates” to have them together in one DWG. Use the command PEDIT (polyline ...
I’m looking for contour for a large area and I don’t really need the level of detail that comes with FBS 1m contours. Is there a more economical option suitable to my project?
Yes! We have OBM (Ontario Base Mapping) available in a variety of vector formats such as SHP and DWG. These maps were produced in 1983 by Ontario Ministry of Natural Resources at 1:10,000 (5km x 5km s...
How can I use the elevation attributes to label my contour lines in CAD?
You will need to create an attribute definition. Here are a few articles that describe the process: How to: Label Coordinate in AutoCAD Tutorial: Create attributes
The DWG files of Ontario Base Map (OBM) does not show the labels for elevations etc. How can I use the properties of the individual polylines to produce annotation?
Here’s a tutorial that shows how to use the features’ properties to apply a label. This is for the latest edition of the software, but there should be similar options available in whatever...
How can I generate a contour file or tin surface from the survey points and break lines in a DEM?
Here are tutorials that demonstrate the general process, although a some steps such as creating the break lines have already been done by First Base Solutions. Youtube: Civil 3D Surface Creation Youtu...
