hello, everyone, 

I entercountered a problem that after I done a wrong operations, on my drawing, all detail view circle and ordinate dimension are at wrong position. it seems that they are offset from its view. I had done more trying but not worked. although I deleted them and re-inserted, it didn't work as well. now, when I insert a detail view, the detail view shows another position detail, now show the detail in the detail veiw circle. and the ordinate has the same issue. when i choose a line for ordinate zero, the zero is aligning another position.
