Before creating pipe networks from polylines, it is best practice to pre-process the polylines to ensure accuracy (no gaps between connected lines) and connectivity (polylines have vertices where other polylines connect). One highly useful tool for this is the Map Clean Up command in Map 3D. To make it more accessible, we have added this command to the Devotech iDAS ribbon, as some users were unaware of its location:
Compact iDAS ribbon
Extended iDAS ribbon
The Map Clean Up tool provides a range of operations that can be applied to selected polylines, including:
Delete Duplicates
Erase Short Objects
Extend Undershoots
Apparent Intersection
Zero Length Objects
Weed Polylines
The Weed Polylines action does not only weed the vertices, but it can also add supplementing vertices:
Unfortunately, there is a known bug that leads many users to believe this action does not work. However, we have discovered that it does function correctly if the supplementing distance is set to half of the desired minimum segment length. For example, if you want the minimum polyline segment length to be 80 m, you should use a supplementing distance of 40 m.
The video below provides more details, including:

How to add length labels to polylines
How to adjust label text height based on segment length with expressions (e.g.: labels for segments longer than 80 m appear larger, making them easier to identify)
