General overview

Draw Vertical Hollow Core Wall starts with a dialog where the user configures the different hollow core elements that make up the wall.

The command continues with a jig where the user can set the desired alignment (Left/Center/Right) when drawing and also rotate the wall.

Offsets can also be added at the start- and endpoint (longitudinal & transversal).

There is also a possibility to return to the properties dialog.

The user can then either draw multiple "walls" by specifying start- and endpoints or add a ridge by selecting two points and then defining a height for the ridge, either with angles, slope, or just specifying it on the screen.

Draw

Draw lets you configure the wall​

• Specify if you want a different type of element at the start and/or the end of the wall​
• Set definition (section) and strand pattern for each type of element​
• Set the rotation (flip) for each type of element​
• Set the gap between the elements​
• Set other properties, such as prestressing, endcap by using “Properties” from the right-click menu​
• Set if and how to cut the continuous elements​. "Yes" will cut the element. "No, shorten" & "No, lengthen" are very similar. If No is selected then there will always be a full hollow core.
• Set model properties for all elements​
• "Flip every 2nd" as the name implies, will flip every second hollow core that is between the start and end hollow core if these are selected. 

The video below shows a Vertical Hollow Core Wall being drawn. In this example, the start and end hollow core is unticked and therefore only one type of hollow core is used. A ridge is also added and the height is here defined by selecting a point in CAD. 

The next example shows how this can be used for sheet piling. Here the "Flip every 2nd" is used and a negative gap to create a sheet piling.
