Prop Line Tool
Draw lines of props and trees like how you draw roads!

This mod will save you time by placing items one by one for you!

Compatible with Campus DLC and Patch

Concerning Campus Update
I've tested this mod with Campus patch and everything is in working order. If you're experiencing FPS drops, please send an output log and screenshot. If you are experiencing issues, please read through the troubleshooting guide Process A. Thank you. (:

How to Use - Official Tutorial Video
Please check out this official collaboration tutorial video between myself, Skibitth, and Paradox Interactive!

- Still need to delete items one by one
- Items placed with this mod do count towards their respective item limits
- See "Quirks" section

- Click to place curve control/draw/anchor points.
- Right-Click to cancel the last point.
- Ctrl-Z at any time to undo the last segment, up to the last 64 segments.
- Alt-Click (purple) any time items are showing to copy-place them where they are without having to redraw the curve.
- Ctrl-Click (green) when placing the last control point (items are showing) to Lock the curve in place.
Once in Lock Mode:
- Click any of the control-points to move them.
- Click on the position of the second item to change item spacing.
- Click on the angle locus (large circle with satellite circle) surrounding the second item to change prop angle.
- Click on the curve itself to reposition it.
- Right click when changing something in Lock Mode to revert it to its last state/place before you "picked it up."
To Place Items and Exit Lock Mode:
- Ctrl-Click or Ctrl-Enter to place items and continue/"unLock".

Options Bar
- This mod places an options bar in the same place and style as where the road tool does in order to switch to Straight/Curved/Freeform draw modes.
- Options Bar will appear whenever a tree or prop is selected.
Buttons on the Options Bar:
- Toggle Fence Mode
- Single: default prop and tree singular placement (hides fence mode and control panel buttons)
- Straight
- Curved
- Freeform
- Toggle Control Panel: Show/Hide PLT's handy control panel.

Control Panel
- Click the button in the Options Bar to show/hide.
Control Panel Features:
Parameters Tab:
- Decouple Button (will show when drawing continuous curves. click to reset items to start of curve.)
- Spacing adjustment buttons and textbox
- Angle adjustment buttons and textbox
- Angle Mode dropdown
- Dynamic: angle items relative to the curve.
- Single: angle items with absolute angle on the game map.
Options Tab: (hover over these checkboxes in-game to see more info)
- Show Undo Previews
- Enable Error Checking
- Show Error Guides
- PLT Anarchy: ignore placement errors and place everything
- Place Blocked Props: like Anarchy but only for items that would be "hidden" by roads and/or buildings that already exist. (Use Prop Anarchy if you want the items to not be "hidden"/blocked).
- Render Items at Vanilla Positional Resolution (see "Quirks" section below)
- Use Mesh for Center Correction: If you have props that are not properly centered within their bounds, attempt to center them based on their mesh's pivot point (if available). On by default.

- You may notice that placed items are not perfectly positioned as they appear when drawing the curve. (Especially when using small items or small spacing). This is a limitation due to the method the game uses to compress position-data for each prop/tree.
*NEW*: Use the Prop Precision mod to fix this issue.

If you'd like to preview exactly where items will be placed at vanilla resolution, I've provided a check-box in the Options tab of the control panel called "Render Items at Vanilla Positional Resolution".

Usage Tips
- Use larger fence pieces where you can to save on prop count. It really makes a difference in the end!
- Place props/trees on roads and through buildings: Enable "Place Blocked Items" in the Options tab of the PLT Control Panel AND enable Prop Anarchy.

Pairs Nicely With
- More Beautification (highly recommended but not required)
- Prop Anarchy (includes Tree Anarchy)
- Prop Precision
- Network Skins
- Random Tree Rotation
- your favorite tree and prop assets!

Incompatible With
Nothing! (So far as I'm aware...)

Source Code
Source code is available on GitHub[].

is there a feature to make random rotations of 0 and 180 degrees? I'm trying to make a few trains but having each car facing the same direction is kinda unrealistic and its pretty annoying to manually change the rotation every time I place a train car

So is this mod still causing FPS drops or has this issue resolved? regarding the Performance Tuning Guide by aubergine18

Could you add an option like "Non Conforming" and allow the vertical displacement of "Control Points" during editing (after the Ctrl Enter) ?

I tried out a curved line and my game crashed as soon as I clicked. Straights and circles work well but the curved one crashes my game.

Yes, I do get an error. It's a window called "Oops!" with nothing inside.

@ Kyjo - No need to shout :p - It depends on tree you use and if the asset creator has made it so they can be randomly sized. This mod does not adjust the size of anything.

@ PelusoNN - Is there something wrong? There really hasn't been any game updates that have required it to be updated.

Is this MOS still maintained?
