Issue Inferencing along the Green Axis...
-
Hey guys, take a look at this screen video I just exported. This has been happening to me for a little while now and it's really giving me the pips!!!!
Red axis inference works as does the blue but green just can't be found...
Is anyone seeing this issue as well?
-
Aren't the red/green reversed in the southern hemi? Maybe you installed the northern hemi SU?
-
Working again now...!!!
-
To offer an answer i would say your camera position is preventing the axis inference...
Click to watch....
I can't get the blue axis in this camera position. I don't think it's a bug more of a drawback of the inference detection at certain angles
-
Ah, that was it....
I had Geo-location set to Ireland.

happens to me all the time. I just orbit around to a different view and grab the object from a different point and then it works. Drives me nuts too.
-
Glad it's not just me, Paul. Might tell Trimblers about it.

Same here.

For everything there has to be some "reason".
To me it seems that (found by trial and error) for all three axes there is quite a large blind spot on the viewport center where SketchUp refuses to pick up the axes inference unless using the appropriate [Arrow] key.
See attached screenshot in which I divided the screen's viewport vertically and horizontally into four equal parts. (with screentext)
Then I checked whether SU could find the axis towards the visible vanishing point. If no, I marked that spot on screen with ***** as screentext. Inside the yellow circle SU lacks the axis inference.
This does not depend on which axis is looked at, only the location of the vanishing point.

In the images @Wo3Dan showed, the intersection of the Green axis vanishing point with the horizon seems to be visible. But if you ponder a moment, you must realize that this point is infinitely far away and can never actually be seen! The ratio of pixel to distance (foreshortening) thus becomes infinite as you move up the view away from the origin! I think this makes it impossible for the inference engine to determine where you are intending the cursor to be in the model, and it gives up.
-
Hi Steve, Have you tried the model I attached?
I only made these observations, ...... marking them all with *****. This does however not explain why SketchUp can't find the axis. (and I don't understand your explanation as to why)
You are right that the vanishing point can't bee seen due to infinit distance. But looking at the 'blind' area on screen this seems to be quite large compared to the entire viewport.
I wonder if the program couldn't be made to narrow down the blind area to something significantly smaller.The model origin's location on screen has no influence.
-
Interesting observations regarding the centre screen inferencing 'blind spot'. This may explain why inferencing is, on occasion, so incredibly frustrating — when most of the time it works like magic. Seems the work-around for now is to draw
outside of that centre circle. -
I opened your file Wo3Dan and tried it out but didn't see any issues...
-
Yes, Gerrit, I tried your model. As saved, inferencing on the green axis indeed fails. But if I orbit so that the axis isn't so straight back in the view, green axis inferencing works fine. Having the green axis oriented too close to the "into the screen direction" in perspective seems to induce the problem, and I was suggesting that maybe this direction causes the inference engine to struggle trying to infer how far back in the "into the screen direction" the cursor is marking in empty space. I should emphasize that my explanation was only a theory - without access to the SketchUp code I'm just guessing based on symptoms.

So did I, to see if my uploaded file was any better, .... fixed something that I wasn't aware of.
But it is still the same, the indicated area inside the yellow "circle" doesn't trigger inference to any of the three axes. Is there no center blind spot at all for you? is this a screen / graphics card / driver depending issue? -
Ok, done it again.
This time it didn't work on the RED or BLUE axis.... Note I was within a component moving other components around. I also tried to orbit around to various locations to trick it a bit but I just couldn't find those two axises...
The only way is to add guidelines which then works.

And just tried a new model with nothing in it....
Can't find the red axis.
