The dynamic position and angle parameters within the inserted blocks appear to be based on the UCS at the time of insertion and relative to the basepoint of the block. These positions don’t change if the UCS is changed or block is rotated.
I can’t work out how to modify the position parameters if the UCS is not the same as that used when the block was inserted.
Can anyone suggest how I access these positions after changing the UCS?
I’ve tried looking at the ECS of the block reference but I’m not sure if that’s what I need to be using.
I worked it out. Thanks as that pointed me in a direcition.
I had to convert the points to the WCS using
and then revert them back into the modifed block.
The complication was that a rotation parameter was changing the blocks transformation matrix between collecting the positions points and modifying them so I had to convert the positions back using the modified br.BlockTransform matrix.
