Issue Description
Your project uses a Complex Profile on Wall elements. However, the Toplink option is disabled or cannot be modified. What causes this behavior and how can this be modified in the settings?

Solution
This happens when the Height Stretch modifier is unchecked in the Complex Profile. To change this:
- Right click on the Complex Profile wall then select Edit Selected Composite/Profile…
- In the Profile Manager, under the Modifiers tab, enable Height Stretch. Two dashed lines will appear which can be moved vertically.
Anything that falls between these two lines will be stretched. So if you want any part in the Complex profile to be at a fixed height, it should not be included within the space.
- Click Apply then Save.
