Modify a construction object
You can modify construction points, lines, circles, arcs, polycurves, and planes using direct modificationfunction that activates the mode where the model objects can be modified by using handles
Direct modification enables additional handles and modification options.
Before you start:
- Ensure that theDirect modification switch is active.
- Select the construction objectmodeling aid that helps in creating and placing other objects
Construction object can represent a point, line, arc, or plane, for example.
Tekla Structures displays the handles and dimensions that you can use to modify the construction object.
When you select a handle and move the mouse pointer over, Tekla Structures displays a toolbar with more modification options. The available options depend on the type of the construction object you are modifying.
To modify a construction object, do any of the following:
|To||Do this||Available for|
|Set a reference point to move in one, two, or any direction||
||Construction points, lines, circle center points, planes|
|Move a point, a point on a line, circle, arc or polycurve, or a plane corner||Drag the handle in the reference point to a new location.||All construction objects|
|Move a circle or arc||Drag the handle in the center point to a new location.||Construction circles, arcs|
|Move a line or a plane edge||Drag the line handle to a new location.||Construction lines, planes|
|Move a plane||Drag the plane to a new location.||Construction planes|
|Show or hide diagonal dimensions||
||Construction lines, planes|
|Change a dimension||Drag a dimension arrowhead to a new location, or:
||Construction lines, circles, planes
Arcs (numeric input only)
|Chamfer a polycurve corner||
|Change an arc to a line
Make a curved segment straight
|Select the arc or segment midpoint handle (with an arc symbol)and press Delete.||Arcs, curved polycurve segments|
|Change a line to an arc
Make a straight segment curved
|Drag the arc symbolat the midpoint of the line or segment.||Lines, straight polycurve segments|
|Add a corner point and an intermediate segment to a polycurve||Drag a segment midpoint handle to a new location.||Polycurves|
|Remove a corner point and the two connected segments||Select the corner point handle and press Delete.||Polycurves|
|Remove the last polycurve segment||Select the end point handle and press Delete.||Polycurves|
|Change the radius of an arc and keep the end point locations||Click the radius dimension, enter a new value, and press Enter.||Arcs|
|Change the radius of a polycurve segment and keep the end point locations||Drag the arc symbolat the segment midpoint handle.||Curved polycurve segments|
|Change the angle or length of an arc||Drag the start or end point to a new location.||Arcs|
|Copy a construction object using offset||Lines, circles, arcs, polycurves|
|Change the modeling direction of the selected construction object||On the contextual toolbar, clickSwap ends.
