grid bubble alignment

[Mohammed_Ata]

Dear, All 

I have a working trick, as shown in the attached picture, the grid line is not aligned with the grid bubble at the end. 

I want the grid line to exactly aligned with triangle head of the bubble. Also attached the family. 

How can i solve it ?

You must edit grid bubble family and assure that grid bubble is placed correct according to reference planes in family template
