Issue:

When executing drafting commands, why doesn't ZWCAD capture the objects when the [Object Snap] is turned on? 

Causes:

Please make sure that the [Object Snap] is already turned on, and check whether the relevant snap modes are selected.

If the above is checked, the possible reason is that the object snap marker and magnet are turned off, and users can't feel it even when the ZWCAD has already captured the object.

Solution:

Turn on the object snap marker and magnet.

Execute the OPTIONS command to open the [Options] dialogue, go to the [Drafting] tab, and tick Magnet and Display smartsnap tooltip and Display smartsnap marker options.

You can also adjust the snap marker color, thickness, size, and Aperture Size in this dialogue.
