How to update without deleting?

[eyal.ch]

Hi Everyone,

I have some frames and I want to delete one Span and frame,

but when I try to delete a purlin made by purlin command:

in this span only, it erases all the purlins.

 

Is there a way to erase only the purlins in the specific span?

Or I should erase all the purlins and start over again?

thank you

The problem is: the one beam you want to delete is part of a joint (could be seen as grey box). 

The joint could only exist, if all members exist. And if you now want to delete one beam, the joint could not exist and so the result is: the joint delete itself.

You have now two options.

Delete the joint and recreate it or delete the grey box and then you could delete one beam ( but could not change the distances between the beams)

Thank you @Sebastian_Eiche ,

But I know those options, I thought that maybe there is a way to bypass this and still have the grey box and the smart connection to exist.

By the way what I did is that I erased the last frame that the purlins was laying on, and it shorten the purlins to be only at the other spans, and it didn't erased the grey box.

good day.

Delete the purlin joint box and adjust the structure manually.
Use the _astm9commtrimextend command to trim the purlins to the new gable frame
