Applies to: ZWCAD 2018, ZWCAD 2017, ZWCAD Classic, ZWCAD+ 2015
Issue:
Double click to open multiple drawings, what we need is that each drawing will be opened with a new tab in the current ZWCAD window. But the result is that every time we open a drawing, a new ZWCAD application will be executed.
Solution:
To solve this problem, execute system variable "SDI", set it to 0 (re-opening ZWCAD may be necessary), then the drawing will be opened with a new tab every time.
