how to cancel a special operation with reactor or something else?

Anonymous — Thu, 28 Feb 2013 08:23:51 GMT

I want to do such work below,

there is a AcdbLine and a AcdbCircle in a dwg, if I move the circle exactly to the end of the line, then dothing, but if I move the circle to other place (not on the two ends of the line),then the circle automatically goes back to its old postion. but how to implement this with objectARX? I guess some reactor object shoud be used.

If I understand you correctly, then we are talking about Associative Framework.

You can read ObjectARX for AutoCAD 2013: Developer Guide > Advanced Topics > Advanced Topics > Associative Framework.

Also useful topics:

it is hard for me to tell something in English correctly.

I want to cancel some operation. For example , I draw a line in Autocad, then I move one end of the line to a new place, is there any way to cancel this operation(move one end to a new place) using objectARX (2008 if possible)

To understand that it is not easy you can read (completely):
