Curved component - wall

Tools: Wall

You can use Curved Component to draw curved 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.

To create a curved component

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

1. Click Curved 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. Click the starting point of the curved component.
   

   • 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.

   

4. 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.

   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.
5. Click the end point of the curved component.

   The secant and perpendicular bisector of the circle appear in construction-line color; the radius (half the value of the secant relative to the semicircle) is marked with a point symbol.

   

   (1) Connecting point = starting point of linear component
   (2) Connecting point = end point of linear component
   (3) Preview of curved wall is attached to the crosshairs
   (4) Center of circle
   (5) Point symbol marks the radius on the perpendicular bisector

   The system displays half the baseline (secant) as the radius, marked with a point symbol on the perpendicular bisector.

6. Define the circle’s direction of extension in one of the following ways:
   • Click a point or an element.
   • Enter the radius in the dialog line.

     Tip: Click the connecting point (= end point) to create a jointless connection.

     Tip: When you have found the radius, you can also click in the workspace - instead of selecting the Enter key - to define the direction in which the curved wall extends.

     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.
