Serious Snap problem...

[ernia]

Hi Lem,
Try snap 3d instead of 2.5d when in perspective or snap in the orthags.

p.s. Hehe. Time for my dog to 3D snap his muzzle to his dog dish. Hope your project turns out ok.

YEah, 3d seems to work. What a bad trap. It should not snap there in the first place when it doesn't align later. You can even zoom in and out and it still stays there. Till you pan... Must be a difference between internal representation and viewport display. Internal is probably not updated, viewport aligns because of some logic, till a refresh by paning or similar is revealing the lack of snap. Well, a know enemy now.... damn...

If you REALLY need to snap a point, and snap isn't doin' it, select the target one and get its XYZ data, select the one to snap and 'set point value' with those numbers. It's too much for everyday use, but it will get both points to the be the same point.

Now, with snaps, remember to turn off snapping to grids and guides unless you need them. What about two 2D snaps--one in plan, one in elevation? Are the objects fairly isolated to avoid other thing confusing the snapping?

[Simon Wicker]

you are just confusing what 2d and 3d snapping does.

3d snapping positions points in an absolute fashion (i.e. the xyz values match) so they are co-incident.

the 2d (and 2.5d) snaps only work in 2 dimensions (i.e. in the plane created by the viewport) so while the point lines up within the plane of the viewport the third dimension is still free-floating and thus your points no longer line up when you rotate the view.

it is a bit like holding up two pens, one six inches away and one at arms length. it is trivial to line these up so one covers up the other but as soon as you shift your head you can see the pens are not really co-incident at all.

cheers, simon w.

Hi LemonNado
use 3D Snapping - Gridline Snapping - Point snapping
.
you can watch the video tutorial here .. Download Snapping (http://www.bleedingpixel.net/downloads/snap%20to%20point.zip) ..1.94 mb .ZIP

Thanks for the replies, and yes Simon, after sleeping over it I got to the same conclusion. Like Eshers Buildings, once you move the POV the illusion crumbles... I tangled myself up pretty well yesterday. Tight deadlines lead to tunnelvision. Btw... I am missing that tunnelvision viewport setting ;)

Have you tried the free COFFEE plugin CPPP? It does exactly that. Even for several points.

Thanks for the explanation on that one Simon. Even after watching the video and noticing it was set to 2.5D I was still wondering.

[LemonNado]

Thanks Jorge, I have to look for that. Sometimes the value of a script or plugin is only understood when one stumbles into the problem it is made for... sighh.

I may be a little late in my reply but I just noticed the topic. I find myself often wondering
whether or not the snapping implementation in cinema is of any use. I tried many times in vain to snap but I am always left confused and amazed to how usless it is compaired to other software.

Just the other day I fell upon this little demo of lwcad it has a excelent snapping system.
I wish cinema would work on theirs.

I snap in 3d only now and it simply snaps where it should snap to. Also the Axis move is easy now.

Hey! I like the way the dimensions show on the segments and midpoints on that demo. . . Sure beats the (confusing to me) measure and construction tool. Which BTW, I also find snap problematic.

A handy hint for snapping without snap is to select both objects then select the points on each object that you want to be in the same place and use weld. You can't miss with this method.

Had to work in Rhino today and must say that Rhino is more awkward with snapping and polymesh editing than C4D. Way more awkward. Other things are rather elegant. But fiddling with a polymesh is a strange experience there.
