AutoCAD Map 3D

[#1]

Any aware if these can be created in map? I can only find 6 year old posts about this so I guess there is no great demand!!

Unfortunately, AutoCAD Map 3D (or Civil 3D) don't have native support for Thiessen/Veronoi polygon analysis.
This has been logged with our development team as a wished enhancement for future releases. However, as you said there is no great demand for this functionality.

The only thing I can suggest is to search on the Internet for existing applications that can do this like for example the OpenSource applications QGIS - www.qgis.org  (with the "ftools" plugin - www.ftools.ca) or GRASS (http://grass.osgeo.org/).

Hope this helps.

Thanks for the reply.

It remains a bit disappointing though that Map 3D doesn't support this functionality and the user needs to go to 3rd party tools. If the 3rd party tools provide the functionality, then there must surely be a demand??

It isn't rocket science to produce these diagrams but it is very tedious to produce them manually.....

Thank you for your feedback.
I fully understand your point and I have forwarded your comments about the importance of this missing functionality to the product development team.
If you want, you can also use the Product Feedback page at http://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=1109794 for providing further comments about any improvements you would like to see within our products.

Thank you.
Kind Regards,

I see you submitting a few "feedback" now that you have a link to that site. 

Good luck.

Indeed - also submitted "feedback" about the dreadful retrograde transparency selection in 2012 but I don't expect a solution any time soon......

I have been waiting for a long time for the Thiessen polygons.  I have used the free package called R, and even the old old ARcView 3.2 could do this.  Map is in last place in the race to get this done.  It is a valuable tool for all kinds of natural resource issues as well as things like radio tower placement.  I wish Autodesk would put some money into getting this done.

There is a free GIS package called qGIS (or Quantum GIS)  - I use it for items like this.  You may want to dump out your data from Map 3D as SHP files (or raster) before you use it.  I have it running on both Windows 7 and my Mac Book.  

It's part of the osgeo.org suite of open source products (that also includes MapGuide).

qGIS has items such as Delauney triangulation and Veronoi polygons (among tons of other items).  Once you have done your analysis, just drag and drop the SHP files back into Map 3D.

Thanks for the source, I will get it for future reference.
