Issue:

Why the calculator's SeqAdd function is not working in ZWCAD and receiving an error message "Objects type of selected is not Text"

Causes:

Because the selected text objects are Multiline Text (MTEXT) type, and the SeqAdd function only works with numbers in Single-Line Text (TEXT) type

Solution:

  1. Click the menu Express → Text → Convert Mtext to Text (or use the MTEXP command).
  2. Select the multiline text objects containing numbers that you want to calculate and convert them to single-line text.
