I cant see the cut pattern in section of concrete , what is the possibilty?
where is the cell file for the pattern?
really i dont understand why this happened , there is no direct solution for this kind of problem
It appears that you have been using Place Linear Form. If you use this you need to apply Part and a Family to that particular object.
When I select the wall you have created and go to "Element Information > Identification > Open Dataset Explorer to Active Part" nothing shows up. This indicates that part/Family have not been applied to that object yet and that is why you are not seeing anything.
I have uploaded my file too so you can have a look.
4075.11 - Copy.dgn
No I select wall componenet as family and concrete as part before .
Guys I changed the parts files to the original files nothing change this drive me crazy ,, any help "very important "
