solidworks refuses to extrude  ... *again*

I wish I could help, but the best thing that I can tell you is that more experience and more care with sketching will just about eliminate this problem.  I agree that it can be frustrating when you can't find what's wrong with a sketch.

Within an open sketch or in edit sketch mode, go to Tools > Sketch Tools > Check Sketch for Feature Usage. SW will find the issue for you.

Follow Deepak's advice. That is an automated troubleshooter that works excellent for problems like yours.

If you RMB a line and select "Select Chain" does it select everything? If it does, delete everything and see what is left. After that, Undo.

hi all

*again* this same problem of either a tiny piece of line somwhere or a small invisible gap in my sketch making program refuse to extrude ...

is there not a quick way to solve this kind of trouble .. this is way too much time spent for what its worth .. btw i feel solidworks should help us with that way more . fix sketch tool and zoom will not do much, most of the time it shows nothing  ...

Marc,

Please don't take this personally. It is not meant to be critical or mean.

The problem isn't so much the software as it is the way you are using the sketch tools. If used correctly,  tiny pieces of line or small gaps should not be created.

Are you rushing when sketching? Fixing sketch problems several times, instead of taking your time and doing it correctly the first time could save you much time & anguish.

Are you using the sketch snapping options?

Are you using the "click-drag-drop" or "click-click" option when drawing lines?
