i just followed these exact steps and the drawing is not updated when i change the values in the data card.
Variable Mapping for AutoCAD Example: Mapping to a Drawing Title Block
To map to a drawing title block:
In AutoCAD, identify the block and attribute name (tag) used in the drawing title block.
In the Administration tool, create a variable named Drawing number.
Click New Attribute.
Under Selected attribute:
For Block name, select Title_1.
For Attribute name, type Draw_No.
Type the AutoCAD file extensions that contain this block, separated by commas.For example, use the following file extensions: dwg, dxf.
In the Card Editor, open the AutoCAD file data card.
Add an edit box and select the new Drawing number variable as the Variable name.
Save the card and close the Card Editor.
When a user adds a drawing to the vault, the .dwg file data card displays the title block information found in the file. Multiple layouts contained in a drawing appear as tabs in the file data card, with values specific to each layout.
Hey Ahmed, have you used the name of the block the autocad attribute is located? If you've used title_1 as the block name it won't write to it, unless your block is named title_1. In the variable settings you'll need to use the block and attribute name as they appear in your autocad file.
