Short description of error
Some models imported from 3ds have rotated elements. One of them can be downloaded from link below. I've attached screenshot what it should look like when imported correctly (not blender).
Exact steps for others to reproduce the error

No problem, here is link:

This file contains chunks that place objects which we currently don't support, which could be the cause of the problem - see a dump:
the diff to create the dump .Since there are keyframes, its possible some of the object placement uses animation keyframes which are currently ignored.
Suspect this is a TODO and not a bug.
I have an answer! I tried following the advice here to clear all object transforms, and all the pieces in the above example snap into place nicely! This has also worked for a couple of other examples I have tried. Though the objects can end up becoming rather large.
So I think the answer is for the importer to offer another option to clear all object transforms, and maybe even default it to true?
OK, that fix doesn’t completely work for everything. It helps with this one, but some pieces are still a little out of place.
Just to confirm, I have tried importing the BL.1.L.3DS example file posted above, with my new clear-transform option turned off and on; with it off, the sofa comes in mostly intact, but with four small pieces in separate odd locations. With the new option turned on, these small pieces are attached to the bottom of the sofa, though two of them end up almost on top of each other, instead of being at the four corners as per the supplied images.
So not perfect, but still an improvement, I would say.
hi @Lawrence D'Oliveiro (ldo) could you reference this here: https://developer.blender.org/T66329 there's still 1 patch to add before yours.
This happens, because the blender import script is reading the first frame of the keyframer. The sofa is part of an animation. It may be useful to add an option if you want to read the keyframer or not.
Also the blender 3ds exporter makes an error by exporting the transformation matrix. 3ds only uses the 3x3 matrix for mesh rotation in local space and the translation part is object location in world space
I made some updates to the script - 3ds has many features, wich are also in the new blender version, wich makes it very compatible
here is the commit: D7454
Been trying the version of this addon that is current as of v2.90.1. Still not quite there yet. For example, I tried importing this scooter model. Compare the difference:
On the left is with your new “Read Keyframe” option enabled, while on the right it is disabled and the “Clear Transform” option from my patch is enabled instead. Notice how the frame around the seatcushion (highlighted) is misplaced in the former.
Current version of my patch:
