Autocad Lisp Count Objects

Here’s a way to count the blocks in your drawing. Use the command BCOUNT and you can individually select blocks, use a window selection or type ALL at the command line and every block in your drawing will be selected.

In AutoCAD, there is no direct method to find number of objects in AutoCAD but you can harness features of quick select tool to do this task. Solved: I have a simple lisp that selects (and holds using sssetfirst) Mtest & Text. I would like it to display on the command line how many objects.

After you make your selection set, hit and in the command line, a list will show the name of the block and the number of occurrences the block either appears in your selection set or if you entered “ALL,” it will show how many times every block appears in your drawing. To see a more full list, hit F2 and a window will pop up. This window is your command line in a bigger format and it allows you to see your command history more easily.

And in this case, allows you to see your list of blocks better. From this list you can select the list and copy and paste it into a text editor if you needed a text file of your blocks (just an idea) (I promise, that when I figure out how to post code using the blog editor, I will post some AutoLISP/VisualLISP codes that do a better job at counting blocks). Hello Jose, I’m happy that this site is useful for you. The command BCOUNT is an Express Tool.

So the problem may be from one the following problems. 1) Express Tools are NOT included in AutoCAD LT. Therefore it will not work. Or 2)If you have the full version of AutoCAD, You may not have the Express Tools loaded.

You can load them following the directions that I made for Loading them with AutoCAD Architecture. You can follow these instructions the same way with regular AutoCAD.

I hope this helps ~Greg. There isn’t a programmatic way of doing a block count like shown in the post. If there LT has Quick Select (QSELECT) you can use it to select all instance of a block by the block name and then use the LIST command to see how many are selected.

The FILTER command is similar and will show you automatically how many objects (block in your case) have been selected [edit] I just though of an easier way depending on whter or not AutoCAD LT has this functionality – Select the block you want to count. Right-click then click “Select Similar” from there you can either look at the command line history or use the LIST command to see the results.

Selection sets are groups of one or more selected objects (entities). You can interactively add objects to, remove objects from, or list objects in a selection set. The following example code uses the ssget function to return a selection set containing all the objects in a drawing. (ssget 'X') AutoLISP provides a number of functions for handling selection sets. The following lists some of the functions available for working with selection sets: • ssget - Prompts the user to select objects (entities), and returns a selection set.

• ssadd - Adds an object (entity) to a selection set, or creates a new selection set. • ssdel - Removes an object (entity) from a selection set. • ssname - Returns the object (entity) name of the indexed element of a selection set. • sslength - Returns an integer containing the number of objects (entities) in a selection set. The ssget function provides the most general means of creating a selection set. It can create a selection set in one of the following ways: • Explicitly specifying the objects to select, using the Last, Previous, Window, Implied, Window Polygon, Crossing, Crossing Polygon, or Fence options • Specifying a single point • Selecting all objects in the database • Prompting the user to select objects With any option, you can use filtering to specify a list of properties and conditions that the selected objects must match.

Note: Selection set and entity names do not remain the same between drawing sessions. The first argument to ssget is a string that describes which selection option to use.
