Modify a construction object

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 represents a point, line, circle, or plane and that helps in placing other objects

    .

    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
  1. Select the handle in the reference point.
  2. To define in which directions the handle can move, select an option from the list on the toolbar:

    You can also press Tab to cycle through the options.

  3. To move the handle parallel to a certain plane only, clickand select the plane.
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
  1. Select a handle.
  2. On the toolbar, click.
  3. Click the eye button to show or hide orthogonal and total dimensions:

Construction lines, planes
Change a dimension Drag a dimension arrowhead to a new location, or:
  1. Select the dimension arrowhead which you want to move.

    To change the dimension at both ends, select both arrowheads.

    To change the radius of a circle or arc, select the outer arrowhead.

  2. Using the keyboard, enter the value with which you want the dimension to change.

    To start with the negative sign (-), use the numeric keypad.

    To enter an absolute value for the dimension, first enter $, then the value.

  3. Press Enter , or click OK in the Enter a Numeric Location dialog box.
Construction lines, circles, planes

Arcs (numeric input only)

Chamfer a polycurve corner
  1. Select a corner handle.
  2. On the toolbar:
    • Clickto create a rounded chamfer, and then enter the chamfer radius.
    • Clickto create a straight chamfer, and then enter the chamfer dimensions X and Y.
  3. Press Enter to confirm the chamfer dimensions.
Polycurves
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
