When creating construction drawings, it’s essential to include building waterproofing details. But how do you design the most commonly used waterproofing membrane family?
This example focuses on a typical roof waterproofing membrane.
Most people know that this can be achieved by using repeating units. By adding these units through the “Repeat Detail Drawings” function, you can complete the drawing by selecting the start and end points. Then, use the “Layout” tool to adjust its presentation format.
However, waterproofing membranes often aren’t just straight lines. What happens when the membrane needs to turn? In those cases, you need to create a separate “Bend” family, as shown in the image below.
Let’s explore how to create this elbow or bend. The angle of the elbow should be adjustable based on the actual design requirements, as illustrated below.
The key element is a variable turning line, which can be controlled through a “Reference Line” to drive the change in angle.
Here’s how to create it step-by-step. First, call up a detail template and lock the top of the reference line.
Next, draw the turning line and lock its top and center to the corresponding reference plane and reference line. Add the necessary dimension annotations. (Dimensions related to angles are linked to the “Reference Line,” while others are connected to the “Reference Plane.”)
The relationships between parameters are established through formulas.
Using this approach, combined with adding filled areas, allows you to easily draw this elbow family. Why not give it a try yourself?
