Hi ,

 

could you help me

 

I need to snap the line feature after line drawn , also need to activate the Edit tool programmatically to select the annotation . 

requirement steps:

step 1  : create a line feature with snapping mode activation

step 2 : select the annotation

step 3 : snap the selected text to the mid point of the created line feature.

 

Intention of the code :

created  3 classes in addin 

one for line feature draw

two for select the annotation

three for button click if necessary

 

created a gdb (D:\Sample.gdb) 

created annotation and line feature classes for testing in arcmap using the addin tool.

 

 

 

 

Thanks

Gopi
