need help in controlling rubberbanding to 90 degrees

I'm more at home using lisp for autocad, but moving my programs
to Vba and need help with a substitue for ortho to controling the
line drawing to a 90 degree direction.

have tried orthoon in vba but it changes the snap to isometrics if i use
a modified version of the example in the help file shown below.

Set objViewport = ThisDrawing.ActiveViewport
OrthoModeSaved = objViewport.OrthoOn
If (ThisDrawing.ActiveViewport.OrthoOn = True) Then
' MsgBox "Ortho is on", vbInformation
Else
' MsgBox "Ortho is off", vbInformation
objViewport.OrthoOn = Not objViewport.OrthoOn
End If

is the better way to control the visual and final drawing of the
block to using the program to only show the rubberbanding in
the x or y direction.

thanks kevin

 

From the Help File:
Specifies the status of the Isometric snap mode for the viewport.


Signature

object.OrthoOn

object

Viewport
The object or objects this property applies to.

OrthoOn

Boolean; read-write See Also | Example


TRUE: Isometric snap mode is on.

FALSE: Isometric snap mode is off.



If you are trying to turn ORTHO on then use:
Dim UserOrthoMode As Integer
UserOrthoMode = ThisDrawing.GetVariable("ORTHOMODE")
ThisDrawing.SetVariable "ORTHOMODE", 1
ThisDrawing.SetVariable "ORTHOMODE", UserOrthoMode

 

thanks for the reply and that was what I needed to make the
routine work correctly. also thanks, had not known of the
setvarible option in vba. changeing to vba, get tired of spending
most of my time trouble shooting if statement in vlisp that don't
go where you programmed them to go..

in the acad 2000 help on orthoon it does not explain that it
controllers the isometeric snap angle. I expected ortho to
do like the ortho button at the bottom of the screen or like
in vlisp the orthomode does.

 

thanks, that what I needed, have never seen setvariable but
will use it in the future. won't use orthoon even through acad
2000 help looks like that is what it is for..
