Curved component

Tools: Downstand Beam, Upstand Beam + Upstand + Strip Foundation

You can use Curved Component to draw curved components (walls). The circle is approximated by a polyline: This results in short, straight segments of linear components, which you can address as a single entity. You can define the number of segments.

Note: Quantity takeoff of curved and circular components is based on the segments.

Schematic overview of curved components and polygonal components

To create a curved component

• A tool for creating linear components is open (for example, Strip Foundation). You have already defined the component’s parameters.

1. Use the Segments parameter on the context toolbar to define the number of segments in a curved component; this number is based on a full circle.
2. Click the starting point of the curved component.
   

   • Haz clic en el punto.
   • Alinea los puntos usando la función de captura lineal y haciendo clic en el punto.
   • Define el punto creando entradas en la línea de diálogo.

   Sugerencia: Para saber cómo introducir puntos en Allplan ve a Dibujo de precisión.

   Sugerencia: El menú contextual y la línea de diálogo incluye herramientas y opciones que te ayudarán en el proceso de introducción de puntos. Para más información ve a la sección Herramientas y opciones.

3. Click the end point of the curved component.

   The secant appears.

4. Click in the workspace to define the direction in which the arc is to extend – relative to the component line (secant).

   

   (1) Direction in which the arc is to extend – relative to the secant
   (2) Connecting point = end point of linear component
   (3) Center point
   (4) Connecting point = starting point of linear component

   The preview shows the direction of extension and the position of the component axis. In the case of multilayer components (for example, walls), you can see the layer structure with the thicknesses of the layers. The position of the first layer gets the number 1, which is the same color as the component axis.

5. Check the preview to see whether the component’s direction of extension is correct. If it isn’t, click Reverse offset direction on the context toolbar to change the direction.

   You can change the direction of extension at any time, even while entering components.

6. By default, the system proposes the last radius used. If this value is less than ½ a, the system automatically proposes ½ a. As an aid to orientation, the program displays a perpendicular bisector which extends to the base line so that you can define the curve of the arc in terms of a center point (without having to enter numeric values).

   

   (1) Center of circle
   (2) Perpendicular bisector

7. Define the radius in one of the following ways:
   • Confirm the value in the dialog line.
   • Enter a new value in the dialog line.
   • Click in the workspace.
     The system drops an imaginary perpendicular to the perpendicular bisector. The point obtained serves as the center of the circle. You can see the value of the radius in the dialog line.

     

     (1) Proposed center of circle
     (2) New center of circle
     (3) Crosshairs

8. Select the Enter key to confirm the value in the dialog line.

   ALLPLAN draws the curved component.

Note: When you use Stretch Entities to modify curved components (at wall junctions, for example) while the component axis is hidden, the modifications you make do not affect the axis. As the axis is no longer within the component, this might cause numeric inaccuracies when you dimension the radius of the curved component. When you use Stretch Entities while the component axis is visible, curved components behave like circles; that is, the component will be moved.
