Hi Xueling7,

How are you ?

I must say I do not write in English very well, I’m brazilian,  so forgive me if you do not understand something…I’l try again, if you need.

The way you can use AutocadMap is the way you need to reach some results, let’s see:

• if you work with raster images, maps, graphic and nongraphic data, you can work very well and linking maps to associated databases;
• you can add data to maps and produce thematic maps with legends;
• you can clean up maps, manage multiple drawings and multiple projects;
• you can build polygon and networks topologies for analysis, queries, etc;
• you can digitize maps, divide maps, work with attribute information, etc.

I’ll suggest you to find on line some free autocadmap manual (you can find it easily) and then avaliate if your work will be better done using all these resources, but in my opinion only having data to attach, topologies to analyse / build or any other result you need you should use autocad map. I think it is a very good software, but you should know what results you need,what kind of project you have in mind, before starting with it.

Good luck and e-mail me every time you need,

Candida
