Solids Builder - Polyline

Polyline - creates a polyline that passes through the list of points provided:

The Polyline activity has the following properties:

• Identification
  • Name - polyline name
    The name of the polyline must follow the naming rules
  • Closed - indicates whether the polyline is closed or open (connects the end point to the start point)
  • Use Centroid - indicates whether the polyline is drawn with absolute coordinates (unchecked) or relative coordinates (checked). When checked, the polyline is moved by its centroid to the position marked by the Center property
  • Vector - vector name normal to the polyline plane
    normally used with the Use Centroid option, to draw the polyline on another plane:
    
    
  • Visible Object - indicates whether or not the polyline should be drawn in the preview
    
    
  • Points - indicates the list of points used to draw the polyline. In AutoCAD, polylines can have arc segments. The Polyline activity also allows this and to create arc segments, you must use points of the type Point / Bulge. In the example above, the point "E" is of this type and has a convexity equal to 0.5

The polyline is the first type of complex curve and requires a point list editor. This editor has a series of buttons:

They are as follows:

• Move to Start - move selected items to the beginning of the list
• Up - move up selected items in a position
• Down - down selected items in a position
• bottom - move selected items to the bottom of the list
• add - add the selected items in the left list (points available) to the right list (points used)
• Remove - removes selected items from the list on the right (points used)
• Select all - select all items
• Invert Selection - invert selection from list
• Apply - apply the list selection to the activity.
  In order to be drawn with the chosen items, you must click this button

If the text is too big/small, or the sphere representing the point is too big or small, use the buttons ( A, a, , ) at the top of the screen to change the preview

Properties (for use in VB expressions)

implements the curves properties and:

• area - polyline area (real number)
• Vector - normal polyline vector ( vector)
• Center - polyline centroid ( point)
