Aligning multiple models

Hi,

I have 2 questions:

1st question:
----------------
I have a very important question regarding imports of objects.

I am still using Lumion 2.2 I did not update to the latest one yet, however, my question is about placing objects.

I have a very complicated scene and whenever I try to export the entire scene to OBJ or DWG it turns huge (my OBJ file was 4GB! and Lumion consumed the system's memory up to 21GB and crashed Lumion) my system has 24GB RAM.

I wanted to export the scene in batches and place them in Lumion (I had a success doing that)
but my problem is accuracy placement.

I would like to know if I can import my obejcts into Lumion and get it placed *where they need to be* without interfearing the mouse movements. (when I import something the mouse place it where it points at!)

my scene has a complex of different catagories of 3D objects (mechanical, electrical, structural, and other type of 3d models) and they need to fit accuratly into the scene.
does Lumion have such an option or feature to do that? like in any 3D modeling software (simply importing into the scene and they are placed in xyz where they were created) ?

2nd Question:
------------------
Is there a way I can acelerate my movement speed in the scene? some of my imported objects went far away in Lumion scene and I had to move like 5 min. (while pressing shift to speed up) to reach it :(


thanks.

2nd question first: go to your Settings and click on the Fast Editor Camera icon, then use Shift key with that on.

1st question:
Try importing a few objects at a time, select them using a multiple selection method, then click on the Property button (see attached scrcap) to bring up the Position Property dialogue.  Change the values to suit.  In v2.2 I have a feeling the dialogue only supported a single object at a time (might be wrong), but in v2.5 you can affect all objects selected at once so its real easy to amend position for lots of objects.

If multiple object selection does not work just use the Property dialogue for each object to change its position.
 
There are some other ways such as using a dummy object for placement positioning, but if above does not work for you then will let you know those steps.

PS are you not able to export with Collada or FBX?  also avoid exporting things like plants etc unless specifically needed from other DCC tools as the poly count is too high and not needed.  Avoid double sided unless needed also to help reduce poly and file size.

You can also use the Align command (in the Context Menu) to align multiple models. This command affects both position and rotation.

Simply search for the "Align" command in the Tips, Tricks and Shortcuts post for more info:
