Unable to update frame

[ankurpraja]

hello everyone,

 

i have a problem with insert frame command.

 

suppose i make square of 1000x1000 mm. and then insert hollow sections on each line of the square.

 

after the structure is complete if i change the size of square. say 2000x2000 mm, then only the sketch is changed and not the hollow sections.

 

so in this case my only option is to delete the hollow sections and insert it again.

 

is there any way to update the structure?

 

thanks in advance
