If you are a long time AutoCAD or IntelliCAD user, you may be used to simply typing the required entity snap at the command line when you want to 'latch onto' a geometric point on an entity - typing end, mid, node etc. This may not work! IntelliCAD 2001 appears to handle entity snaps differently to IntelliCAD 2000.

Intelligent Snaps

Out of the box, ICAD 2001 now features the flyover 'Intelligent Snaps' found in AutoCAD Rl14 and this may cause problems if you try to type the OSNAP setting after starting a command. The osnaps do not appear to work in the way that they do in 2000. 

There are several 'fixes'.

You can turn off the fly-over feature. To do this type PR and adjust the Enable fly-over snap settings as shown in the figure below.

If you really want to wind IntelliCAD back to an early state, disable fly-over snaps and enable the aperture box. IntelliCAD then works like early versions of AutoCAD. 

However, this does seem a rather retrograde step and short sighted as flyovers can be useful. It is better to learn to use them as discussed below.

It is better to ensure that the entity snap toolbar is showing (using View>toolbars. Then look closely at the toolbar. Running object snaps are indicated by a depressed icon. Int the figure below, END and QUA are on and so the cursor snaps to the quadrant of the circle when a command is started and you are asked to select an entity.

Now when you issue a command such as LINE and try to lock onto an entity and type an object snap, (say MID) the command will work you will be rewarded with the equivalent of AutoCAD's Intelligent snaps.
