ericepv Posted February 25, 2017 Share Posted February 25, 2017 I am having trouble with importing a DWG topo map. I watched Chief's video 1056 (Import a Surveyor DWG file for a Site Plan or Terrain Perimeter) and I followed the instructions for joining all of the perimeter polylines but I still cannot get the entire set to highlight so that I can convert it to a Terrain Perimeter as shown. I have also tried creating my own Perimeter by tracing over the lines in the imported DWG and then placing the imported elevation lines on top of it - no go. I noticed that when I imported the DWG, I got (2) sets, a large one with no elevation lines and a much smaller set (off to the lower left) which does have the elevation lines. The layers of most relevance are: - 4 (elevation lines) - 8 (elevation labels) - 17 (Perimeter) Can anyone can figure out what I'm missing?

RL-inc Posted February 25, 2017 Share Posted February 25, 2017 Not at my computer right now to look at the file but I would suspect that you are missing something in the steps of the import process. When you import are you selecting terrain perimeter for the boundary line layer and elevation data for the contour lines? In regards to not getting the boundary lines to join that sounds like an issue with cad or snap behavior settings. Link to comment Share on other sites More sharing options...
glennw Posted February 25, 2017 Share Posted February 25, 2017 OK, lets first deal with the terrain perimeter itself. I think what is happening is that when you are importing the data, you are telling Chief to import the terrain perimeter. So what is happening is that Chief is creating a rectangular terrain perimeter over the small plan to the left. Once Chief has created this terrain, it won't create another one as you can only have one terrain in a plan. Display only the Terrain Perimeter layer, select and delete the terrain perimeter. Now you will be able to create your own terrain perimeter. Link to comment Share on other sites More sharing options...
Alaskan_Son Posted February 26, 2017 Share Posted February 26, 2017 or...is it possible your polyline isn't actually closed? Try going around and checking your connections or maybe try clicking Close Polyline. I opened that DWG up and noticed that not all the perimeter polylines are actually connected.

ericepv Posted February 26, 2017 Author Share Posted February 26, 2017 Michael - The file I posted is the original file which was sent to me. I did enclose the perimeter and also connected a few other lines but it still didn't work, I've attached the file here (I should have done this originally). Any thoughts?

Here's a quick video... Link to comment Share on other sites More sharing options...
ericepv Posted February 26, 2017 Author Share Posted February 26, 2017 Michael: Thanks for the video, that worked great! I now have converted it to a terrain perimeter but it is just a flat lot (should be sloped) even though I brought in the elevation lines (and specified them as such during the import) along with all the other layers. Any idea where I went wrong? Eric Link to comment Share on other sites More sharing options...
