Drawing a circular component as an arc - wall

Circular component - wall

To draw a circular component as an arc

• The Wall tool is open. You have already defined the component’s parameters.

1. Click Circular Component.
2. Use the Segments parameter on the context toolbar to define the number of segments in a curved wall; this number is based on a full circle.
3. Define how you want to enter the end point of the arc:
   • Enter end angle
   • Enter end angle based on delta angle
   • Enter end angle based on arc length

     You can change this setting later.

4. Place the center.
   

   • Click the point.
   • Align to points using the linear snap function and click the point.
   • Define the point by making entries in the dialog line.

   Tip: To find out how to enter points in Allplan, see Precision Drawing.

   Tip: The shortcut menu and dialog line provide tools and options to assist you in the process of entering points. For more information, see Tools and Options.

   The component is attached to the crosshairs. The preview shows the direction of extension and the position of the component axis. The previews of walls are complete with all construction layers and surface elements.

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.

   Tip: While entering elements, you can quickly change the component axis by means of keyboard shortcuts or in the dialog line. In the case of walls, you can also change the component axis by means of drag-and-drop editing in the Properties palette.

   

   To modify the component axis in the dialog line, do the following:

   • Use the TAB key to activate Set component axis.
   • After you have placed the start point of the wall, the following options are available:
     • Press the + (plus) key to tilt the wall about the axis.
     • Press the '-' key (minus) to move the axis within the component to the default positions; this is the same as clicking , and in the wall's Properties dialog box.

   You can also modify the component axis using shortcuts.

   The following shortcuts are available for modifying the component axis:

   • Using CTRL+^, you can tilt the wall about the axis; this is the same as clicking on the Wall Context toolbar.
   • Using CTRL+<, you can move the axis within the component to the predefined positions; this is the same as clicking , and in the wall's Properties dialog box.

   In addition, the dialog line provides a convenient way of modifying the component axis using the keyboard.

     • Press the '-' key (minus) to move the axis within the component to the default positions; this is the same as clicking , and in the wall's Properties dialog box.
6. Define the radius of the circle in one of the following ways:
   • Click a point.
   • Click an element. Consequently, the circle is tangent to the element.
   • Enter the value for the radius in the dialog line and select Enter to confirm.
7. Define the starting point of the circle in one of the following ways:
   • Click a point.
   • Enter the starting angle (counterclockwise, relative to the horizontal x-axis).
8. Define the end point of the circle in one of the following ways:
   • Click the end point.
   • Click Enter end angle in the input options and enter the end angle (counterclockwise, relative to the horizontal x-axis).
   • Click Enter end angle based on delta angle in the input options and enter the delta angle (relative to the starting angle).
   • Click Enter end angle based on arc length in the input options and enter the arc length (relative to the starting angle).

     Allplan draws the circular component as an arc.

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.
