Many CAD users know that blocks can be repeatedly inserted to reduce unnecessary operations, therefore are widely used. Double-click blocks to enter the reference editing or block editing and we can edit objects in the blocks.
What is an attribute block?
Attribute blocks are blocks plus some text attributes and the text can be easily modified. Attribute blocks are widely used in engineering and mechanical design. For example, the axes in the following architectural drawing are one block, but the attribute values are 1, 2, and 3.
We can define similar objects as one block and adjust the display of blocks by modifying the attributes. When the text attributes in some blocks need modifications, we can add attribute text in the blocks and define them as attribute blocks.
What’s the difference between attribute text and regular text?
We have briefly introduced the concepts about blocks and adding attributes to text, so what’s the difference between attribute text and regular text? It’s actually pretty easy: just draw a circle, write a 1 using Single Line Text in the middle of the circle, and then select the circle and the “1” to make them block and you can see what happens. Try yourself and see for yourself, I have summarized the differences as shown in the following:
The biggest difference is that attribute text is very easy to modify: double-clicking the attribute block would pop up Enhanced Attribute Editor and we can modify the attribute values or we can modify the attribute values in the Properties Panel (CTRL +1) by selecting the attribute blocks.
The regular text in the blocks is like other graphics, if you want to modify the text, you have to Explode blocks or use block editing command: Refedit or bedit. As a result, when defining blocks, we can define text that needs to be modified as attribute text and define other text that need no modifications as regular text.
