Within the latest 4.40a, the following tools are available to help draw certain road markings. These are.
Parallels (Car Parking Spaces)
First, open the model and select lines --> Road Hatching/ Yellow Box.
Road Hatching
Once the Road hatching tool has been selected we can start by indicating the two boundary lines. (These are the curved horizontal lines). n4ce needs to know this information so I can calculate the width necessary for the hatching lines that will be generated. Following this n4ce asks for the two vertical lines on either side. You will then be prompted to input a spacing, this is why indicating the two ends is essential.

Yellow Hatching
Once the Yellow Box hatching tool has been chosen we can start by indicating the boundary line (This is the yellow lines shown within the image below). Following this select a length of the line using two points within the boundary. Now indicate the length of the crossing hatch. We have now given n4ce enough information for it to calculate and insert the correct lines.

Road Dashes
Once the Dashes tool has been selected, we can start by indicating the start and end of the first dash followed by the start of the second dash. Next, select the end of the last dash along the road markings. Indicating these positions allows n4ce to calculate the length, distance, and overall number amount of markings necessary.
ZigZag
Once the ZigZag tool has been selected the following dialog appears.
Set the code to the appropriate code to draw the linework.
The next section defines how the shape of the Zig Zag will be controlled, the three options are as follows.
- Sketched: This mode would normally be used to trace over an image. Where the dashes can be seen clearly.
- Indicated Points: This mode allows the tool to pick up surveyed points.
- Line Feature Points: This mode allows the tool to use the points in a feature with a single click.
The Settings section has the following options:
- Add points to List: This will add any points generated to the Select List so that they can be easily selected after if needs be.
- Prefix Created Points: This will add the letters RL to the point numbers of any new points that are generated. This is so that they can be seen to have been generated not surveyed.
- Delete Indicated: This option is only available if no DTM has been generated. If the new features are being generated from either Indicated points or a selected feature, this will delete the indicated points to leave behind just the new clean detail.
The following options are available to define the levels of the new points:
- Null: Sets the heights of the points to nothing, i.e. makes the points 2d.
- Constant: Sets the heights of the points to the same given level.
- Linear Interpolation: Interpolates the levels of the points from the selected points or feature.
- Model Interpolation: Derives the levels of the points by dropping them vertically onto the selected surface.
Having selected the appropriate settings, press Ok. Start by indicating the start and end of the first dash followed by the start of the second dash. Next, select the end of the last dash along the road markings. Indicating these positions allows n4ce to calculate the length, distance, and overall number amount of markings necessary.
Parallels (Car Parking Spaces)
This link shows some examples of what is possible with this tool.
Once this tool has been selected the following dialog appears.
Set the code to the appropriate code to draw the linework.
The next section defines how the shape of the Zig Zag will be controlled, the three options are as follows.
- Sketched: This mode would normally be used to trace over an image. Where the dashes can be seen clearly.
- Indicated Points: This mode allows the tool to pick up surveyed points.
- Line Feature Points: This mode allows the tool to use the points in a feature with a single click.

- Delete Indicated: This option is only available if no DTM has been generated. If the new features are being generated from either Indicated points or a selected feature, this will delete the indicated points to leave behind just the new clean detail.
- Skewed Lines: Allows the parking bays to be generated at a skewed angle rather than perpendicular to the first edge.
- Closed Ends: Closes the bays to form a rectangle for each.
- Add Center Line: Adds a line down the center of the bays.
- Extend Start: Adds a bay to the opposite side of the start line,
- Extend End: Adds a bay to the outside of the last bay.
- Intermediate Points: Adds more points where the center line crosses the bays.
The following options are available to define the levels of the new points:
- Null: Sets the heights of the points to nothing, i.e. makes the points 2d.
- Constant: Sets the heights of the points to the same given level.
- Linear Interpolation: Interpolates the levels of the points from the selected points or feature.
- Model Interpolation: Derives the levels of the points by dropping them vertically onto the selected surface.
Having selected the appropriate settings, press Ok. Start by indicating the start and end of the first parking spot followed by the next parallel line. Next, select the last parallel along the parking area.
Give Way Marking
Once the tool has been selected first indicate the bottom left --> Right then the top of the Road Marking Triangle. Note: This tool will place three points that will join using a line depending on your specific code setup. The fill is located on the dedicated CAD backcloth as a solid fill.
