AutoCAD Map 3D

[#1]

Sorry, at work Youtube videos are blocked by firewall, so I can't see it.

Anyway, issue _MAPWSPACE and turn it on,  then in Display Manager => NEW => LAYER

 

This applies to my glorious Map2006, so in your version it might be different.

what exactly do you mean by join?

i placed A-21, A-22, C-21 as texts in autocad. i just linked them by loading the excel using mapattachdb, double clicked the sheet, defined the link template, clicked the link records and selected the objects. is that it??

[#3]

May you attach your Excel file?

For me, join=link...
Do you speak italian, or only spanish? 

[#4]

i am a filipino actually, so i can only speak english

here is my excel file...

[#5]

No way, lady.

As suspected, your spreadsheet does NOT contain the A-21, A-22, C-21 values, so you cannot link automatically Acad objects to Excel records.

In XXI century, we don't join them manually one-by-one, so please feed your .XLS table with those values. 

When you're done, issue the _ADEGENLINK command, and choose the "Enclosed text" linkage type.

Haha. sorry about that, i am actually a chem engineering student, and autocad is not my thing..

hope you'll reply for further more questions
