Where is last rotation angle stored?

[Anonymous]

Hi everyone,

I was layed off at the end of October and so i was out of touch. But...i'm
ba-a-a-a-a-ck.

I am using *command* in a lisp routine to *rotate* a selection set. After
this is complete, i want to know how much the user rotated the set. I looked
for a sysvar like *distance* that stores the last value from the *distance*
command but there is no *rotate*.

Is there something or someway to determine how much the user rotated the
selection set?

Thanks

Sal

Welcome back, Sal.

I think you are after LASTANGLE.

Hi Jason,

According to my notes, LASTANGLE:

Stores the end angle of the last arc entered relative to the XY plane of the
current UCS for the current space.

I haven't tested your theory yet but is the end angle of the last arc the
same as the last rotation angle? It doesn't sound like it.

I started a new drawing, inspected LASTANGLE (it was 0), drew a line,
rotated it 90, inspected LASTANGLE (it was 90).

However, the help files do agree with what you are telling me.

Hi Jason,

I did what you did and got the same results. But then i tried it again with
a different rotation and got the same 90. So i drew another line and tried
again and with another new line and rotated it and got 0.

When i try drawing an arc with:

Command: a ARC Specify start point of arc or [Center]: c

Specify center point of arc: 0,0

Specify start point of arc: 3,0

Specify end point of arc or [Angle/chord Length]: a
Specify included angle: 45

Command: lastangle

LASTANGLE = 135 (read only)

This clearly should have shown 45 degrees, according to the help files. I
don't know what is going on.

FYI: I have Win98 and AutoCAD Mechanical 2000i (not Mechanical Desktop)

Thanks for your continued assistance.
Sal

Sal,

Since seems to be no saved rotation angle, you could redefine the rotation command to add a global variable of your own.

Not in the box, but after seeing your request I realized
that it would be a simple matter to add this sort of
functionality to the InputManager class in my AcadX ActiveX
server (see www.caddzone.com/acadx/acadx.htm).

So, as of today, AcadXInputManager has the following new
read-only properties (which should be self-explainatory
with the exception of LastDisplacement, which is the
displacement of the last MOVE/COPY/STRETCH operation):

LastDisplacement
LastDistance
LastRotation
LastOrientation

These were also declared, but
are not hooked up yet:

LastColor
LastCorner
LastEntity
LastInteger
LastKeyword
LastPoint
LastReal
LastScaleFactor
LastString
LastSubEntity


A quick demo:
-------------------------------------------------------
Command: (setq acad (vlax-get-acad-object))
#

Command: (setq iman (vla-getInterfaceObject acad "AcadX.InputManager"))
#

Command: .ROTATE

Current positive angle in UCS: ANGDIR=counterclockwise ANGBASE=0
Select objects: LAST
1 found
Select objects:
Specify base point: 0,0
Specify rotation angle or [Reference]: 45
Command: (setq ang (vlax-get-property iman 'LastRotation))
0.785398
Command: (angtos ang)
"45"
Command:
----------------------------------------------------------

Very impressive! Thanks Tony.
