Create dynamic links within relativized VAV graphics that point to associated AHUs. Build reusable graphics with proper relative navigation.
When creating relativized VAV graphics, you need links that navigate to the parent AHU, but the AHU path differs for each VAV instance.
Use relative paths and relationships to create dynamic links that work across all VAV instances.
If VAVs are organized under their AHU:
Link in VAV graphic:
ord: ../../ (navigates to AHU parent)
Add a reference property to each VAV pointing to its AHU:
ahuRef property to VAV componentstation:|slot:/Equipment/AHU-1ord: ../ahuRefUse Project Haystack tags:
ahu markervav and ahuRef pointing to parentord: ../ahuRef-><hyperlink>
<ord value="../ahuRef"/>
<label text="View AHU"/>
</hyperlink>
Or using bound label:
<boundLabel binding="ord:../../displayName">
<hyperlink ord="../../"/>
</boundLabel>
