Yes. See the Register_Blocks document for information on registering your blocks. However, it may be necessary for you to edit the tag string in the attributes of your blocks. Occasionally, attributes are not completely defined in blocks. The program uses the tag string to differentiate between the attributes in a block and to register the fields. Q: How long does it take to register my AutoCad blocks? A: Most blocks can be registered in a minute or two. It depends on the complexity of the block. For example, an instrument bubble typically only has 2 attributes, one for prefix and one for number but a drawing frame can have many more attributes in it. Obviously it is going to take longer to register a drawing frame than an instrument bubble but typically it only takes 10 to 15 minutes to register a drawing frame.
