Build custom AutoCad fields into Dynamic Blocks and write extraction code for AutoCAD LT

I have developed a series of Dynamic Blocks that contain attributes and custom properties. Primarily our company uses AutoCAD LT for design work and I would like someone to build fields into these blocks. Ultimately I would like to to extract field data into a table that can be totaled - Maybe with an ATTEXT script? Perhaps their is a better way or an extraction program, but it must be suitable for AutoCAD LT 2015/16. The fields I need generated are mostly repetitions of block properties such as polar distances and viability states, however I would like to add values so that I can extract that information and quote with my drawings. These costs need to be variable based on Polar Parameters ie IF (Polar Value) A < AND > B (Field) = C I have a library of parts and if successful with first stage of the process there will be opportunities for more work. The DWG attached has a single Dynamic block (PANEL BLOCK) Fields needed: 1. ) Field name: TRUE VALUE [ CENTER TO CENTER LENGTH ] and [ CODE ] (polar parameter) (vis state) eg. field displayed as [ 3.3 L 80/32 ] 2. ) Field name: ROUND VALUE (for viability states without an S eg. DL 80/50) IF [ CENTER TO CENTER LENGTH ] is less than 1.3m field value equals 1.1 IF [ CENTER TO CENTER LENGTH ] is greater than 1.3m and less than 1.8m field value equals 1.6 IF [ CENTER TO CENTER LENGTH ] is greater than 1.8m and less than 2.5m field value equals 2.2 IF [ CENTER TO CENTER LENGTH ] is greater than 2.5m and less than 2.9m field value equals 2.7 IF [ CENTER TO CENTER LENGTH ] is greater than 2.9m and less than 3.4m field value equals 3.3 IF [ CENTER TO CENTER LENGTH ] is greater than 3.4m field value equals ERROR: CHECK LENGTH 3. ) Field name: ROUND VALUE (for viability states with an S eg. DLS 80/50) IF [ CENTER TO CENTER LENGTH ] is less than 1.3m field value equals 1.1 SHEETED IF [ CENTER TO CENTER LENGTH ] is greater than 1.3m and less than 1.8m field value equals 1.6 SHEETED IF [ CENTER TO CENTER LENGTH ] is greater than 1.8m and less than 2.5m field value equals 2.2 SHEETED IF [ CENTER TO CENTER LENGTH ] is greater than 2.5m and less than 2.9m field value equals 2.7 SHEETED IF [ CENTER TO CENTER LENGTH ] is greater than 2.9m and less than 3.4m field value equals 3.3 SHEETED IF [ CENTER TO CENTER LENGTH ] is greater than 3.4m field value equals ERROR: CHECK LENGTH ATTEXT CODE REQUIREMENTS: ATTEXT CODE 1.) LIST: TRUE VALUE ie: TRUE VALUE ----------------- 3.25 L 80/32 2.6 D 50/50 1.6 DLS 80/50 3.3 NLS etc . ATTEXT CODE 2.) LIST: INSTANCES OF ROUND VALUE ie: ROUND VALUE INSTANCES --------------------------------------- 3.3 5 2.7 1 2.2 2 1.6 4 1.1 1 3.3 SHEETED 2.7 SHEETED 1 2.2 SHEETED 2 1.6 SHEETED 5 1.1 SHEETED 1
