I am using a Civil 3D corridor to represent a site perimeter fence in 3D, the model will also be used for 2D plans. I use the corridor alignment for the 2d plan representation, fence linestyle etc. I have created a dynamic block representing the the standard gate (bowtie) symbol, is there a way to associate this block with the alignment so it appears at nominated chainages?
You could create a "dummy" design profile that had grade breaks at the specific locations along the alignment that you have gates, then use a grade break alignment label style linked to that profile with the dynamic block as the marker. However, changing the locations of these gates would not be dynamic and would require you to change the "dummy" profile grade breaks.
