Panel panelIconId 1f449 panelIcon :point_right: panelIconText 👉 bgColor #FFFAE6 To parametrically align the skew angle of the cross-frame with the skew angle of the support line, you can follow these steps: Copy the skew angle value of the support line using the "Copy Parameter" function. Paste this parametric expression into the skew angle value of the cross-frame. By doing so, the skew angle of the cross-frame will be dynamically linked to the skew angle of the support line.
