Generate tree shading
Click on the Generate tree shading tool. Select the topographical height measurement and tree height measurement.
A prompt will come up asking whether the tree height is given from sea level (N - no, not a true height) or from the ground level at that point (Y - yes, true height).
Finally select the tree block.
A couple of important things to note are:
- The tree has to be a either a block object or a circle.
- When you select the tree height measurement PVcase will scan the site survey for tree height numbers on the same layer.
- The software matches the height numbers to the nearest trees that it can find. For the trees that don't have a measurement near them PVcase will simply do an offset.
- You can manually create tree heights by copying custom tree height measurements on top of your DWG tree blocks but you have to place them on the same layer.
Generate SLA lines
The tool is used to check the placement of frames on 3D terrain. It is an indicator on what PVcase based the frame generation upon. If the generation calculation is correct - the pink lines should reach another frame row at some point.
After pressing Generate SLA lines button select if you want to draw up indicative placement lines for the entire PV area or only a couple of selected frames.
Then select any topographical height measurement and the PV area.
This tool does not represent the shading from the frames - rather it represents the so called 'shading limit lines'. These lines show the parts where the shading limit would intercept the next frame above it at the height of that frame.
Adapt to terrain
This tool is used to adapt a copied framed to the terrain. It allows for full customization of PV areas.
After clicking on the Adapt to terrain button you have to select the starting frames for each row that you want to rearrange. Meaning, when you copy a frame to a row you must select that row's starting frame. The starting frame of a row is the one closest to the alignment side.
Select Y (Y - Yes) or N (N - No) if you want to align half-frames towards the trench.
Finally select entire row(s) with the newly added frame(s) for adaptation.
Note: You can use this tool for multiple frames at once.
