Hello, I am looking for a lisp to help speed up the process of renumbering a selection of multileaders. We use multileaders to call out materials on our drawings, and often make changes to our Bill of Materials (BOM). Whenever a change to the BOM is made, we need to adjust a lot of the multileaders to match. For example, we may have a list of 30 materials, all numbered and bubbled out. Then our client comes back with a change, and we have to add a material between number 15 and number 16 (We can't just add the material to the end, because the BOM is organized by category, size, etc.). This means that every number from 15 to 30 increases by 1, and then all of the multileaders need to be adjusted. Currently we use one of two methods for adjusting the numbering. If it is a small list, or there is not a lot of bubbles, we just manually adjust each multileader. If its a long list, or there's a lot of bubbles, we use find and replace (In the example, check find whole words only, find 16, replace with 17a; Find 17, replace with 18a; and so on. Then once all numbers are adjusted, uncheck find whole words only, and find a and replace with nothing). While these methods work, they are rather tedious, and prone to error, especially when we have a long list of hundreds of materials. I would like to find a faster and more robust way of doing this, and I think a lisp is probably the best solution. Ideally, the lisp would allow for the user to take a selection set of multileaders, input a range of values to adjust by a user-specified delta, and then make all the changes in one go. In the example above, the user would get the selection set of multileaders, input a range of 16-30, and a delta of 1. Sometimes the delta would need to be more than 1, hence the requirement of a user inputted variable. Often, a material is removed from the list as well, which requires a range to decrease by one. So if the lisp could take that into consideration and allow for a negative delta that would be helpful as well. I have attached a dwg example with the multileader we use for reference. The multileaders are of the type Block, using Circle as the source block, and they are always in paperspace, not sure if that will affect anything. If anyone has any ideas, please let me know. Thanks, Noah BOM MULTILEADER EXAMPLE.dwg

Hello, I am trying to figure out a way to get all of my common data (detail numbers, sheet numbers, and when I bubble an item from my BOM) to update easier. The best way I found to do this seems to be using Field. Field works with regular text really well, but I cant figure out how to get the correct data from Mtext or from a table. Meaning, Field pulls all data from Mtext, and only table data from tables (i.e, nothing inserted inside the table, just table height and whatnot). I would like to use a table so that I can copy paste my BOM from excel, and Field reference to the data in that table. If you have an easier solution I would appreciate that too.. Using full Autocad 2017, Mechanical. Also, I tried using Custom Drawing Properties but that maxes out at 10, and I cannot populate it easily from the excel file. I know I can use sheetset for the sheet numbers, but see no way to use it for the BOM.
