Moving multiple objects results in skewed move?

[shauncarollo]

I've been working on a file for work--a 40+ something furniture layout for our new office that they want a fly-through animation done of. I'm setting up materials, camera paths etc. when I realize that when I move some objects, some move more than others when I select them all at the same time. I've tried to reset the world scale which is the only thing I could find after a quick search with no luck. What gives?

Firstly try opening your file, make sure all your viewports are in wireframe mode and save the file. Then close max and open it again. This is to clear your graphics card RAM.

 

Try selecting your objects and moving them and see if it still does it. I've had this before when my Graphics card has run out of RAM so try and steer clear of having lots of big bitmaps displayed in your viewports.

Andy, Thank you for the suggestion. Unfortunately that did not solve the problem. In case I wasn't clear in my original post, here are two pictures showing what I have selected before the move translation, and the result. You can see how some objects are moving much more than others. I've never had this happen before.

try parametric array.........

Do you have CAD drawing in there as well ?? CAD drawings creates these kind of issues.It messes up with world coordinate space.Let me know if you CAD in there so we'll talk about it more.

Try the various (sorry, jargon failure here...) pivot center options on the toolbar. Screen instead of local. And the drop down next to that. Group instead of individual.

Are items linked? If you select the parent and child then it may cause the child to travel twice the distance (I think this depends on your Reference Coordinate System and your Use Pivot modes).

 

To test, select everything, click un-link and then try moving them.

I do have the furniture model (.dwg) in there that was given to me by our furniture designers. I have messed around with changing some of the pivots when everything is selected. I will try all the suggestions tomorrow when I'm back at work and see if those help.

 

Thanks guys.

This really seems to be similar to CAD import problems due to point of origin. It messes up max as it comes in too far out from the origin (0,0,0) coordinate. To fix this in case of CAD drawings, copy the drawing with base point (CTRL+SHIFT+C) and choose the center of the drawing, open a new file, and paste (CTRL+V) at the origin (0,0,0). Import to max again and problems are gone. If not, it may be due to scale problems. Say your drawing in CAD is in mm (1m=1000mm). If max is set to meters, instead of having a 1m object, you'll have a 1km object. This gives you basically the same problem... a huge scene.

+1 to Daniel.Most likely CAD has messed up with coordinate space.To cross check this, just open the cad drawing in Autocad.Press z ,enter, press a & enter to see how big is the space.Your drawing would look very small.If it does then just follow the steps Daniel has given.

I opened up the file in autocad and typed in units. Units are set to inches, and the scene is close to the origin. Autocad file is around 28MB uncompressed if anybody wants to take a look. I believe the max file is 31.4 uncompressed.

Come on, Shaun, you can do this... Ok, so things are fairly compatible. What are your max units? How big, in autocad, is the building? Where did those chairs come from? Simply rescaling in max won't do... If you get by with "mixed" scales in the beggining, eventually it's gonna get to you. If everythnig is correct, then try merging the scene into another one. If that fails, we'll try something else. I believe Abhay and I and allot of people out there dealt with the same issue at some point. You just really gotta pay attention to the units, origin and scene size (not file size). By the way, a 28mb autocad file is pretty big. Is that already 3D? And before I forget, cad blocks and few other elements should be avoided.

there is a script called 'mesh reset' that is useful for this

it unlinks all that awful autocad / revit geometry and deletes empty blocks and nulls

The 28MB file is 3d, fairly correct/complex geometry. All the units, and their respective dimensions make sense; ie a door jamb is 36", and again, the scene is in the 1st quadrant, as close to the origin as it possible can be. I will try the mesh reset as soon as I'm back in the file--I'm getting a new workstation today that is a beast! so I might just play around all day seeing how much faster 16 cores are than 2, and testing out the new K4000

good luck

you will need it lol
