moving things while working in 3d

[Anonymous]

 am barely starting to work with 3d in autocad. I am experiencing problems when moving objects around.

First I make my current screen view xy plane. So that I can move things around. Then, for example when i grab something and move to somewhere else, it seems fine in my view. But then, when I orbit the drawing, i see that although it seemed correct place in my previous view, now i discover that in fact in the other plane it went to completely irrelevant location which i never intended . how can i prevent things like this? How are you moving objects around in 3d? 

Also for example is there a way to make autocad treat your view as if you are drawing on a 2d drawing and ignore the 3d snaps while you move things around in your current view in 2 d ? This way i would not be surprised later when i orbit and see that in the other plane it went completely in a wrong direction

Hello @Anonymous, 

I see, I totally understand. I am not sure what version of AutoCAD you are using. 

You have several options you can use for your workflow. 

Help moving 3d objects

1. Utilize the  "Group Objects"

2. Keep all the 3d parts etc. on the same layer & use QSELECT to select all objects in a layer

3d Views

1. Use "Top" view for all 2d operations(to view & draw in 2d)

so if your current xy view is top view and that is how you work, will these surprising snaps in other (xz and yz) plane would be prevented?

and also I didn't understand the relevance of the other things you said for the solution: you said group objects and work in layers. how would they prevent these surprising snaps in other planes? do you mean, if you put objects in layers, you can turn off irrelevant layers while working so it would be less confusing and prevent unnecessary snaps? and what about grouping?

by the way I am using Autocad 2018,

and, my drawing so far is an extremely simple drawing with just several objects only

Try moving the objects by entering the coordinates.

Use the @ to position Relative from the given basepoint. Then give a value for you X and Y movement.

When you also want to move in Z also give this value.

When u want to move to 'set' coordinates use the # to position on the exact coordinates from the drawing origin.

Or when in 3D view use the MOVE Gizmo and do select the plane you want to move on.

being XY, XZ or YZ.

Or use the axis move from the MOVE gizmo.

Hi,

UCSDETECT (Dynamic UCS) could be affecting your placement of objects.

Also, when you have a 3D object such as a cube and you use Object Snaps in moving the item you might consider working in a non-orthographic view.  In 2D you could be choosing your move base point as a top corner of the object but if clicking a destination point on another object you might get a bottom point.

I have always promoted to my students that working in a 3D view is best practice when manipulating 3D objects.

Hope this helps,

Blaine

If you want to move objects of a 3D model parallel to the screen using screen picks first set the current ucs to be parallel to the screen (UCS V [Enter]) then set osnapz to 1.  If you turn on the OSNAPZ system variable, all object snaps are projected onto the XY plane of the current UCS or, if ELEV is set to a non-zero value, onto a plane parallel to XY plane at the specified elevation.

If you want to move an object in 3D using keyboard entered distances relative to the current location I suggest first turning off dynamic input ( dynmode 0). Now select the object and give the move command (m) and simply type the delta x, delta y, and delta z values for the move relative to the current ucs.  For example, m [Enter] 1,2,3 [Enter]  will move the selected object 1 in x, 2 in y and 3 in z.
