Radius

If graphical pick functionality is not required, for example: precise dimensions have to be entered. The user can enter the dimensions into the Radius and Arc Angle fields from the Create Curved Wall window.

The Radius textbox displays the radius of single-arced shaped wall. To lock or unlock the radius value click Radius locked.

The radius value can be set by:

• Typing a radius and click Enter.

• Click Measure Length and graphically selecting existing elements to establish the radius.

The Arc Angle textbox displays the arc angle of a single arc shaped wall ranging from 0‑360 degrees. To populate it type a value for the arc angle then press Enter. Arc angles can be entered in any of the following formats:

Alternatively, click Pick Arc Angle to invoke the Positioning Control window allowing the user to make graphically selections of existing elements to establish the arc angle.

Note:

The start of the arc remains stationary while the picked point projects an invisible line to the centre of the arc and the end of the arc snaps to this line thus creating the arc angle.

The Position section of the window is used to establish the centre position of a single-arced shaped wall. It can be populated several ways:

• Establish the correct direction from the option lists and type the co-ordinates.

• Click Graphical Pick Start to invoke the Positioning Control window to graphically pick the position. The co-ordinates are populated automatically.

• Alternatively, the first two methods can be combined by utilizing the padlocks. Click Coordinate locked to unlock a value or click Coordinate unlocked to lock the value. A locked value is displayed in grey.

The wrt (with respect to) textbox displays the element name to which the start position co‑ordinates are positioned to.

The Orientation section of the window is used to establish the Direction and Rotation angle of the wall.

The Direction textbox displays the direction of the wall (defined from the start to the end positions).

The direction may be changed using a number of methods. The direction can be re‑established by typing a new direction (for example: U, N, N45E, S30W15D) then click Enter.

Two other methods can be used to set the direction of the wall.

The Pick surface or edge to define direction allows the user to graphically pick the face or edge of an existing element.

The Rotation textbox displays the rotation angle of the curved wall. To populate it type a value for the Rotation angle then click Enter. Rotation angles can be entered in the same formats as Arc Angles.

Alternatively, click Rotate angle using two picks to invoke the Positioning Control window allowing the user to make graphically selections of existing elements to establish the rotation angle.
