Some more questions

Is there any way to turn off the snap mode when moving an object? Sometimes, I'm in top view and I just want to rearrange things, and not have objects try and snap to each other.
I'm pretty sure the answer to this one is 'No', but it never hurts asking. Is there any 4-view for SU (top,left,right,perspective)?
hello chipp,
for rearanging in any view, try not to "grab" the item while moving. instead, click on it, choose move, and then klick somewhere else (read: blank space) for the start point of the move... this way you make sure, for example in top view, you will move it only along the green and red axis. and even while moving it diagonally, the object will not move along the blue axis.and for the close group question: if you do a right click outside of your group, you can see in the context menu "close group/component". and now that you know, where the command is, you can define your own shortcut!

Thanks everyone for the help here! Much appreciated
Was there anyone who could answer the question about how to show a scene camera's positon?
Thanks again.

chippwalters,
Here are two skp’s (in 3DW) explaining how to go about:
(5 camera locations)

Thanks Wo3Dan, those tutorials very helpful. I can deduce then there is no way to 'show' the camera position from an existing scene unless one previously set the camera to specific object's postion. IOW, you have to create an object first, then set the camera position to it.
-
Wo3Dan,
I also found many of your other tutes valuable, especially the one on aligning a polygon face perpendicular to an arbitrary path in space. Thanks!
-
Chipp, to get the camera position of an existing page/scene:
Draw a horizontal (parallel to the bottom edge of your screen) line/edge anywhere on a horizontal face in the model, then move that edge vertical (blue-axis) until it matches "exactly" the model horizon.
Now, starting at the "exact" center point of your screen, on the edge now located at the horizon, draw a blue-axis vertical edge down to your horizontal face, then draw a line on that face to the "exact" center of the bottom of your screen...this is the first line pointing to directly below your camera position.
From another point on your horizon edge draw another vertical line done to the same horizontal face, but now, using your "lookaround" eyeballs, rotate this vertical so that it is at the "exact" center of your screen again (move the eyeballs along the horizon so you can keep the start and stop points horizontal). Repeat the line from the bottom of your vertical to the bottom center of your screen...your second pointer is drawn.
Now zoom out and continue the two lines until they intersect: below the camera, so draw up vertical to the height of the horizon edge and you have it!
Now I can go to sleep, thank you very much.
Best, Tom. -
Tom,
Thanks for that! Thought about it and I think one part may be wrong. The height of the camera is not necessarily the same height as the horizon, is it? For instance, a camera could be pointing up, no?
After thinking about it some more--the camera's pointing has nothing to do with it's position. Maybe you are correct. I'll check it out

Chippwalter,
Sorry, I didn't notice that you want to approach this the other way around.
Just upload a simple favorite example skp so that I can show you how. Include a scene that you want to be reproduced in another scene (NOT A SCENE COPY!) with the camera in the skp in 3D-space. Mind you it's not going to be 100% but almost. -

Chippwalter,
(Working on it, the "hardest" thing is to save steps to make things clear, not forgetting anything)
b.t.w. in 'Shadow Settings' you can adjust ligth/dark and especially in your case: Display (shadow): on ground. I disabled that for good reasons
-
Yeah, sorry for leaving it on. I was rendering in Podium and wanted the shadows! BTW, do you know if there's a way to extrude a curved surface, or a curved path? Thx.
-

What I meant is not turning off shadow but just that "ground (Z=0) will not show shadow". Your floor is below Z=zero. It's "underground", so to speak. The shadow at groundlevel is in the way. See your scene5.
(camera W.I.P)
Extruding a curved face: no
Extruding along a curved path: yes(*)(*)
- the curved path is coplanar: no problem
- the curved path is 3D: the cross section of the extrusion will twist along the path.
-
Huh. Didn't know about shadows not projecting below sealevel. Thanks for that. Podium didn't seem to mind and rendered just fine.
What I meant by extruding a path, was actually taking a path, and offsetting it, and stitching the polys in-between.
-
Nevermind about the extrude curve thing. It appears the CurveStitcher plugin will do the job.
-
Chipp, your question about the height of the camera gave me pause...but I still think I right(?). If you use the eyeballs to change your view you'll see the reference edges on the horizontal face and at the horizon move together, but if you use the orbit tool you are changing the height of the camera.
Keep me posted (though I keep expecting someone to point us to a ruby that will do this for us...and exactly! :`)
-
OK, I looked at it. Thanks for doing this, but while I understand how to find the target, and the height offset, I'm not sure I follow the rest of your construction. You have constructed several polygons. Which came first? TIA.

Here one:
(see previous posthttp://sketchup.google.com/3dwarehouse/details?mid=3bde59bd2cb2eb715953c2937bcaaf81)Chippwalter,
Here is your skp with one scene (nr.6) reproduced:
(click on C1, C2, C3 and so on till 'closup of target')http://sketchup.google.com/3dwarehouse/details?mid=7dca37346949e03d6887b7fa740aa743
Several tools you can use:
-From scene6 zoom in real close using the eyeglass (=Zoom tool), not your mouse.
This will let you pinpoint (mark) your target.
-The Walk tool will reveal the actual height from scene6 in the VCB
The camera is located on the line that I drew towards the little vertical line in the canon (CANNON?!?#)
The rest is pure constructial and a bit of trial and error to find the camera
Try to figure it out and let me know. -
OK then, maybe this is what you mean by "extruding a path" (see attached skp file).
You can also copy it along the z axis and hand stitch the polylines together but that's slower.

really great stuff in here.....

Hi bonj (and welcome)
I hope you can find some useful stuff here...
