How to pass ObjectIdCollection into built-in Rotate command?

[Anonymous]

Hello,

First time user here. I am trying to rotate a bunch of entities like so:

This image represents a bunch of lines, blocks, circles etc being rotated using the built-in AutoCAD rotate command. 

Knowing that I can access all of those object IDs and store them into an ObjectIDCollection, how do I go about passing that collection into the rotate command? Is this possible? Or do I need to build a rotate command from scratch? Perhaps there's an easier way of doing all this ...?

Hi Gilles,

I have a question for the rotate class. How would you go about specifying to start the angle at an actual 0 instead of starting the angle from where the object actually is? I'm not sure if I'm being clear on this...

I took a screenshot to demonstrate:

Basically either I start the angle from the current angle of the entities OR I can start from zero. I'm trying to implement this in the RotateJig class but I can't really grasp where to modify the code so that it doesn't start from its current angle (if specified)... 

Thanks

Alex

Hi,

I do not understand what you mean with: "the angle from where the object actually is".

AFAIK, only some entites as BlockReference, DBText, MText have a Rotation property which can be different from 0, and so, been used as reference angle.

For others entites as Line, Polyline,... , you cannot say if the have been rotated or not, so you cannot have another start angle than 0.

Hi Gil,

I came across this as I have the same problem, except that I'm trying to pass the selection set to a lisp command through the SendStringToExecute() method.

It is a CADMEP Fabrication lisp function which functionality is not exposed by the .net fabrication API.

Is there a way around this? Either by passing the selection set as string or by using something other than SendStringToExecute()?

Thanks,

Select the objects in your .NET code, so they become the Previous selection set, then just pass "P" to the LISP code via SendStringToExecute() or SendCommand()

If the LISP code has a function that's not a command-function but a function that takes arguments, and it can be registered using (vl-acad-defun) then you can use the Application.Invoke() method to call the function from managed code.
