I'm going to preface this post by saying I'm a complete newbie to mapping with AutoCad. That being said, I do have experience with other CAD products.
The project: Taking survey data (x,yz) where x,y are coordinates and z is elevation and drawing a 3d polyline in the program. It is my hopes that I can do so over a basemap of the area we are working in. I am hoping to do this as simply as possible.
I was wondering if someone could speak to the basics of how to do this or provide me some good references to use. In addition, I am a student (this project is for engineers without borders) so I have access to a wide variety of CAD and GIS suites if you feel that one will suite my needs better.
Thanks in advance,
Thanks for the reply! I don't have much now to take a screenshot of. Let me try to clarify my intent?
We are contructing a water pipeline in a foreign country as volunteers. Our survey team recently surveyed the area and gave us various coordinates for the pipeline.
They are in the form <Easting,Northing,Elevation>
I am able to plot the line to problem using these points; however I would like to incorporate a basemap of the area to go under this data. (e.g so that the points of the pipeline corrsepond to a point on the map).
I guess i'm just wondering what the best way to approach this project is.
Well, if you want to put a background aerial image under your 3Dpoly, you may _MAPCONNECT to a WMS server like http://wms.latlon.org/?layers=osm
If I understand you correctly, you wish to draw a polyline between a set of xyz points.
I use civil3D. I don't really use Map3D but maybe the commands are similar or if you also have civil3D, then it is pretty easy:
- insert menu, import tab, create points from file (say ENZ space delimited for x y z file). Each individual points will automatically be assigned a number starting at 1.
- now you can create either a 2D or 3D poly depending on your needs - similar process.
- command 3DPOLY (PLINE for 2D)
- when it asks to specify the start: type the following to specify you'll reference point numbers: 'pn
- then when it asks for the point number type in the point number range to include: 1-50 (assuming you have 50 points)
Hopefully the process is similar in map3d.
PLINE for 2D
The above command closes automatically the chain, while a simple _LINE command will create an open one in the 1-N range.
I wonder why the OP wrote "I am able to plot the line...": I think he'd like only to have a background imagery under his existing polyline...
