AutoCAD Structural Detailing

[#1]

In prosteel, you unlock constraints, then you can use stretch to adjust frames, then you relock constraints.

Is there a similar method in ASD

currently when stretching the end of beams, they default to move with amount of the stretch.

Hi I have the same problem, I'm actually disappointed that nobody posted a solution as this is a common operation as designs change constantly and If you have to make rapid changes... Re-assigning all end treatments, grating sizes, hand railing etc. Will be sooooo mundane and time consuming!

PLEASE SOMEONE HELP

Hi thanks for the reply!

Actually no it does not stretch/extend members it also moves them? What I want is for instance a row of secondary beams joining it's main beams e.g. 1000 centers apart and now the the distance changed to 1500 centers apart.

Now, if I move the main beams to 1500 obviously the secondary beams stay put. Instead of having to go thru the long operation of extending each and every beam and re-attaching it's gussets and cleats etc. I thought I could use the normal stretch tool under  home_modify_stretch and select all member incl. the main beam? This is not stretching the members it only moves them.
