Issue：

some of our users have reported that they have encountered this problem when they are openning multiple drawings, see below pictures.


Cause:

As the prompt said, there is not enough memory space (RAM) for ZWCAD to open more drawings


Solution:

  1. Please try to close some of the unneccessary application or some of the current opened darwing to free some memory.
  2. Try to use the 64bit version of ZWCAD, since there is no limitation of memory use for 64bit version theoretically.
  3. You can try to increase the virtual memory, the method is to right click on my computer - Advanced - Performance Settings - Advanced - Change Virtual Memory - Set the minimum and maximum of the D drive to 1.5 to 2 times the memory of your computer. (Don't take too much)
