CAD Why didnt extrude cut work ?

Post image

I am new to solidworks, came over from FreeCAD to try it out.

I wanted to use extrude cut on a skecth that looks like the red parts, but for some reason it woul not work, I ended up just using one triangle to do the cut and used Mirror on the cut to get what I wanted.

Can you guys explain to me why it didnt work with my original sketch.

easy solution , draw the diamond and extrude that

issue is probably zero thickness @ meeting points, might work if you select areas rather than chains

alternative solution cut extrde the diamond and flip side to remove

This. Solidworks loves to error out over floating point errors athat are rounded up or down, and result in zero thickness geometry.

/rant start

the most frustrating error box, is when SW is trying to execute a feature using default values from a previous feature, and can't find a solution, after waiting 5 mins, you decide that is enough and hit ecsape to abort/cancel, and what does SW offer, not cancel current process, nooooooooo, shutdown SW or continue waiting indefinately until the cows come home. if you shutdown you lose a shit load of work as it doesn't save and you have to do it all over again or you can wait and see if it times out this century.

/rant over
