ignore backfacing while selecting

[isaac_cm]

I discover that even I choose "ignore backfacing" option when selecting vertices I still able to select backface vertices also !! any advice for that ?

 

I use Max design 2009 with last hotfix applied !

 

Thanks

ignore backfacing is useful for any kind of selection like edges and vertices at least this is what the instructor told me !!

 

when you have 35 vertices and you can select them with a selection drag or you want to just select them one by one ??

Ignore backfacing is extremely useful when selecting vertices or edges etc. It works with all sub obj types.

Just be aware you can still select vertices that are "through" your shaded object if the vertices is attached to a face that's normal is facing you.

Agreed, you can use the facility in older versions of max and it is very useful.

IMO this is a major failing of max's selection tools. most other apps (modo, c4d, xsi) have raycast selection which means that you can only select forward facing elements that are visible to the camera. max 2010 is supposed to address this but i downloaded the demo a couple of days ago and although the paint select works better, it still doesn't work as it should.

[/url]thanks Gus_Rayvus and all guys for explain but I am very agree with derek forreal !! this stupid behavior of selection making alot of trouble to me !! if you follow my previous post I found a strange faces in my polygons, maybe this because I select the behind vertices accidentally while modeling now I suppose to select them one by one and count them to make sure I did not grape the wrong vertex!!

 

I have polyboost plugin , can some one please tell me how I can use it to select only the vertices I am facing or any other solution to this ??

 

really stupid thing in a major software like MAX

 

Thanks

There are very valid reasons to want to select backfaces - doing a lasso/marque selection of a 'leg' or portion of an object that you want to get 'all the way around'.

 

If you couldn't select in the above manner, then you'd have to select each face presented to you and then rotate the model to continue selecting the previously hidden faces.

 

I grew up on Max 8 and modelling complex mechanical models (cars, spaceships, robots, etc) and the ability to toggle the ignore backfacing is a blessing.

 

Use it when you need it, turn it off with a single mouse click when you don't.

 

I really think HOW it's interpreted depends upon HOW you first learned modelling.

 

To answer your question, you can select a face that is towards you, hold the control key down while selecting Vert or Edge mode and the verts or edges associated with that face will be automatically selected for you.

 

You can select an edge, then RING or LOOP the selection, then hold down the control key while selecting Vert mode and the verts associated with those edges will be selected.

 

You can also GROW or SHRINK your selection.

 

You can also do a marquee selection and then hold the ALT key while marque-unselecting some unneeded verts.

thanks for your advices, I know the select backface vertices is also important , but as I said the option "ignore backfacing" is not ignoring backfacing at all !!!

agreed - i'm not saying that backface selection isn't needed, infact, as you say it is a necessary selection method.

 

but so is the ability to select only polys that are visible to the camera. look at my example. i select some of the external polys (bottom left viewport) but i can't avoid selecting the polys inside the tube (see perspective view). i must either select the polys one by one, or use one of the methods you describe above. but the methods max offers are workarounds IMO, and none are as fast as a simple raycast paint selection.

exactly... but is it possible that no one report this to Autodesk !!
