Remove tilt of object with respect to WCS

Anonymous — Mon, 04 Dec 2017 10:35:39 GMT

Hi all,

I got a 3D AutoCAD model (one block) which is unfortunately tilted with respect to the WCS. I would like to adjust the orientation of the model - e.g. allign it parallel to the WCS axis. Is this possible and how?

Thank you for your help!

Hi,

>> e.g. allign it parallel to the WCS axis.

Command _ALIGN ...? 😉

Or command _ROTATE and use option _REFERENCE (>>>details<<<)

Align would be great, if I could chose the WCS as the second object - is this actually possible?

Draw a line horizontal in WCS ... the line's endpoints are your destination points 😉

Thank you!

XLINE Hor would create a horizontal line with respect to the WCS in 2D, right?

Is there sth as XPLAIN for the 3D case or would I have to use HOR and VER?

Within my object are a number of blocks which I want to move aswell -> GROUP command? Can I mark all objects within my scetch? I keep missing most of them when using the lasso.

If you are in the WCS at the time, then yes, XLINE Horizontal would do it. If somehow you need to do it from within some other UCS, a routine could be worked out to let you do that.

If you want to MOVE all the pieces of your object, you can easily do that if you can do it immediately after Exploding the object -- use the Previous option in object selection in the MOVE command. But in that case, it would be simpler to Move the object as a whole, before Exploding it.

Hello @Kent1Cooper,

ok, It displays WCS in my sketch, so I guess, that 's fine.

Unfortunately the object is already exploded - is there a way to move it as total anyway?

Thanks!

That doesn't jive with Post 1 that says "(one block)", which I would assume is what you used in Aligning. If it's Exploded before Aligning, presumably you were able to select all the parts resulting from Exploding it, for the Align command. If so, you can then Move the Previous selection. If that's not viable for some reason, can you describe your process, i.e. by what steps you got to this point?

The second points can be entered as absolute coordinates by prefixing the coordinates with an asterisk *

Command: ALIGN

Select objects: 1 found Select objects:

Specify first source point: _endp of

Specify first destination point: *12,12,12

Specify second source point: _endp of

Specify second destination point: *12,24,12

Specify third source point or : "press enter"

Scale objects based on alignment points? [Yes/No] :

Right you are @Kent1Cooper - sorry, the object was updated after my first post and now it consists of about 302 blocks. I think I will try marking all of them with

qselect (https://forums.autodesk.com/t5/autocad-forum/how-to-select-all-objects-on-a-particular-layer/td-p/5503882)

and then group them, create the lines with xline - one horizontal and one vertical - and then align.
