Issue:

There are many modes for object snap, and users need to set the desired object snap modes according to their actual needs. Where can this be configured?

Solution:

On the software status bar, right-click the Object Snap button and check the desired object snap modes from the menu. Alternatively, click Settings to enter the Drafting Settings dialog box (the DSETTINGS command can also be used to call out this dialog).

The value of this setting is controlled by the system variable OSMODE.
