Snapping Objects to Other Objects in WinCan Map
A common technique used during data processing and also useful at a site inspection level is being able to snap objects together in 3 dimensions in WinCan Map. While WinCan Map only presents itself on screen as a 2 dimensional plan, it is actually fully 3 dimensional and all coordinates are always being handles in 3 dimensions at all times.
...
The node ID is pre-populated, because you had the node selected on the right hand side before starting this series of mouse clicks.
The node has X, Y and Z coordinates which are taken from the observation that you snapped to.
You will need to enter the ‘Type’ and ‘Node Type’ again like you did previously in WinCan VX, but this does not take any serious amount of time.
You can add some other information if you wish. Do not enter a ‘Node Depth’ value when plotting any type of Modelling Node, but it is Ok OK for manholes, catchpits and other Drainage Asset types, due to the reasons described in Being Smart with Z Values.

For this example, we will plot the connector node CN_GY3000_CP1.1 in WinCan Map VX and then create the lateral pipe from GY3000 to CN_GY3000_CP1.1.
In this example, we will not create the connector node first in VX, and will work more directly inside WinCan VX and assume that there is no observation code to snap to, so we are just going to create a connector node on the section line at a point that suits us.
The process is here is very similar to the previous section except that we ignore the first part about creating a node in WinCan VX and go directly to WinCan Map. As expected, there is no connector node waiting to be plotted on the right side because at the moment it does not exist in the data.
Again, working clockwise around the screen as before, select the WinCan Manhole layer, then the Tools ribbon, then ‘Draw Point’ and this time when you get to the ‘Snap to’ part:
Select the ‘WinCan Sections’ as the snapping layer because we are going to snap to the pipe this time.
Select the other magnet button which does not have a dot in the middle. This is for picking up a line object in WinCan Map.
Hover the mouse pointer anywhere over the section line and see the cross hair come up - you can click at any point to create the connector node and then fill in the details in the node entry form as before:

Snapping to a line on another layer.
Again, you can go back to the connector node that you have just created in WinCan VX and review its data, and then create the lateral.
In this example, it will not be possible to make the section-lateral link because there was no junction/connection observation code to snap to, so this is as much as you can do right now. Maybe there will be some additional inspection data that comes into the project at a later date after which this can be cleaned up.

Snapping to a Node
For this example, we will do nothing more than create a section from GY3000 to CP1 in VX and review the results in WinCan Map.
The result will be a section from GY3000 to CP1.1 and there is nothing else to do. Remember, it is a section because it does not have connector node at the downstream end. The clinical difference between sections ans laterals has nothing to do with the asset’s size, material or length.
