Any way to lengthen centermark in drawing

[tim11_manhhieu]

I want to extend a point of the center mark as shown in the picture.

I know a little about ilogic but this case seems too much for me, can any expert help?

Execution sequence:
1) select the left center mark (base)

2) select the right center mark
3) select the side
The center mark automatically extends and stops when it meets a point of another center mark.

(AB extend until B meet C)
Or if there is a simpler sequence that would be great.

This is a built in feature in Inventor.

Right click before you place your points, and select "Free Points" from the options as shown below:

Then click both holes, and you will have the line connected between them.

Amazing, i didn't know that, 

maybe inventor should have a notification to remind users to right click,

i think not many people know this.

You wouldn't believe all the stuff that can be found in that "pre-place" right click menu.

You can even start  "Centerline" and click on both hole
