Extruding edge is not properly working

[Anonymous]

Hi, 

Im encountering a problem when extruding edges.. Whenever i extrude edges and i want to move them, it only give me a limited face or it doesn't work properly.. please see the attached images to this problem.

im new to maya and right now im learning  to model a human face by watching a video tutorial . I'm starting to use "create polygon tool" in "front View"then after that i want to extrude the edges and so on.. but im stuck on extruding edges because it doesn't move properly or the behavior is not as expected as the tutorial im watching.. maybe there are settings that i need to fix first before proceeding.. Thanks for your help.

Hi there, I can see from your last screen shot that you have point snap turned on. This may be the cause of your problem as it looks like the centre of your edge has snapped to the corner of your polygon. Try turning point snap off and see if it behaves as you would expect 🙂
