hi all its been a long time
 

i have been working on this just for a little bit obviously but as i have been working last night i noticed that all the vertices had seperated (so that edges ran randomly thru the peice ... as it does not have too much geometry yet it was OK to just methodicly go thru and stitch them back together ... but it leaves me with the question "what did I do to cause it in the first place?"
i have attatched this file just so you can see the way I am working tho i have currently no verts that are unattatched

Any ideas/sugestions would be much apreciated:bow:

further info that may be relevant
 

i have just been extruding edges and merging verts. ... this has ment that every now and then I have had to set the Normals to Face
if that helps:bow:
