Solids Builder - Arc 3D

3D Arc - creates a 3d arc with center, radius and convexity, making elevation transition between start and end:

Arc 3D is used to model pipes that have a certain curvature in plan:

Obviously this curvature is small, but it avoids the need to create several connection boxes, or even manholes to make the change of direction in the network.

The 3D Arc activity has the following properties:

• Identification
  • Name - name of the activity
    The 3d arc name must follow the naming rules
  • Point 1 - name of the start point of the curve
  • Point 2 - name of the point end of the curve
  • Extend Start - a VB expression that stretches the start of the line:
  
  
  
  • Extend End - a VB expression that stretches the end of the line
  • Offset - an VB expression offsets the line from the axis formed by the given points of a distance in the XY plane
    
    
  • Object Visible - indicates whether or not the point should be drawn in the preview
    
    
• Offset Dimension
  • Offset Distance - distance of the dimension line in relation to the points that form it
  • Dimension Offset - indicates whether to draw a dimension at the offset
  • Offset Template - a text template that provides the dimension
    Use <> for the dimension (Example: Offset = <>)
• Initial extension quota
  • Detachment from Initial Prol. - distance of the dimension line in relation to the points that form it
  • Dimension initial extension - indicates whether to draw a dimension on the initial extension
  • Prol.initial Template - a text template that provides the dimension
    Use <> for the dimension (Example: Start = <>)
• Final extension quota
  • Removal of Prol. End - distance from the edge of the dimension in relation to the points that form it
  • Quote Prol. End - indicates whether to draw a dimension on the end extension
  • Prol. End - a text template that provides the dimension
    Use <> for the dimension (Example: End = <>)

If the text gets too big/small, or the sphere that represents the point gets 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 methods:

• Radius - arc radius (real number)
• Bulge - arc convexity (real number)
• Center - center of the arc ( point)
