CAD tip # 6678: Question CAD% platform category Sequential numbering in AutoCAD blocks If you need to insert blocks with incrementing numbers in attributes, or automatically renumber existing blocks in your DWG drawing, you can use the free CADstudio InsertC utility. InsertC contains two commands - InsertC and BlockC. The InsertC command is a 'counting' version of the command. It inserts a specified block and automatically fills its first (resp. Specified) attribute with an increasing number in a series. You can either specify the block by picking an existing reference, or by entering its name.

I had this interesting request come in by email: I have a problem where I have a block I need to insert into several parts of a drawing. The block has three. CAD blocks are named groups of objects that act as a single 2D or 3D object. They’re used to create repeated content, such as drawing symbols or standard components.

The BlockC command takes the selection set of existing blocks and fills (renumbers) their first (resp. Specified) attributes with a series of incrementing numbers.

You can sort the blocks (influence the numbering order) by their selection order, or by their X- or Y- coordinates. Both autonumbering commands allow to specify the starting value of the counter, the prefix (you can also add leading zeroes) and the postfix for the generated number. You can also use the insertc:Inc LISP variable to set the increment (if other than +1), insertc:Prec for decimal precision (for decimal increments) and insertc:AttNo to specify the attribute number. (setq insertc:AttNo 2) The LISP utility InsertC is available for download on See the animated sample (click to enlarge): ACAD ADT. CAD 17.5.2009 47911×.

Autocad Blocks

Use the Express Tools command BCOUNT to generate a list of blocks. Follow these steps:. At the command prompt, enter bcount.

When prompted to select objects, either make a selection or enter all. Press F2 to open the AutoCAD text window. A list of blocks and the number of references present in the drawing will be displayed in the text window.

For AutoCAD LT, the BCOUNT command does not exist because the program does not support Express Tools. As alternatives, use the QSELECT, FILTER, or SELECTSIMILAR commands.
