Quantities For Phases

Someone in the office was complaining that I didn't include everything that I could have in my last post; so I am going to expand on what else you can do with Map. In this example I will add object data to some polylines.

To start we are going to need to create an object table. To do this go to Map>Object Data>Attach/Define Object Data

Create a new table. In the new window that pops up give it a name that you like. In the field definition area type the field name you want to use (remember no spaces in the name). I am going to add streetname, fill in description and default and click add. Make sure the type matches the values that you are going to use, ie character for words, integer for numbers. You can add more but that is all I will need today. You can always come back and add more. If we have standards the tables can be added to the templates.

To add object data to objects go to Map>Object Data>Attach/Detach Object Data. It will ask you which table to use, select the one just created and then press the Attach to Object < button. Select all of things you want to add data to. Once you have selected all of the items hit enter. To see what we have done select an object and look in properties to see that we have added object data to the object. You can change the value in the properties.

You can then do what I did in the last post, but this time go to the object data under the properties folder to add it to the export. With a little rearranging and editing you can then copy the information out of Excel and bring it into AutoCAD as a Table. So you end up with a table showing each street and the lengths of each street. This is not limited to streets Jason used it to report the lengths of the wetland encroachement for a project.

The ability to annotate the objects is also possible, this will add a label to the objects with the information we just added to the polyline.
