Project: HiCAD 3-D

Rotate Sketch Elements

Sketch > Transform > Rotate

Use this function to rotate graphical elements or isolated points of a sketch. When you call the function, the Rotate dialogue window will be displayed:

The currently active step will be highlighted with an orange frame in the dialogue window. After calling of the function these steps consist in the selection of lines or points.

Step 1: Select option

Use the symbols at the top of the dialogue window to specify the handling of connected lines during rotating.

Step 2: Select elements

Select the lines or isolated points that you wish to rotate in the drawing, or use the functions of the context menu that you can open with a right-click during the selection process.

	Connected lines or edges* Use this function to select all lines or edges that are connected to the next identified edge in one step. The lines and edges will be selected up to a point where a continuation would no longer be unambiguous. This function can also be activated with the help of the SHIFT key: If you select a line while holding down the SHIFT key, all connected lines will be automatically selected as well.
	Tangentially connected lines or edges* Choose this function if you also want to select all tangentially connected lines or edges when identifying the next line or edge.
	Lines in rectangle (CTRL+LMB)* Use this function to select lines by means of a selection rectangle. Please note that only lines of the active part will be considered. If the rectangle is drawn from the top left to the bottom right, all lines which are completely located within the rectangle will be selected. If the rectangle is drawn from the top right to the bottom left, lines only portions of which are located within the rectangle (i.e. intersect with the rectangle) will be selected as well. The selected lines will be highlighted in a different colour. You can also call the function via the keyboard. Proceed as follows: Move the cursor to the position of the first corner point of the rectangle. Hold down the CTRL key and the left mouse button. Release the CTRL key and draw, while still holding down the left mouse button, the rectangle. When you then release the left mouse button, all lines/edges within the rectangle will be selected.
	Cancel (Esc) Cancels the function.

*Normally, already selected lines and edges will be de-selected if you click them again.

For the above functions marked with an asterisk *, however, the following applies: If you click lines that have already been selected or if already selected lines are located in a selection, they will not be removed from the selection.

The selected elements will be highlighted in the drawing and the number of selected elements will be shown in the dialogue window:

Press the middle mouse button to end the selection. Click the icon to expand the selection.

Step 3: Select axis and specify rotation angle

After completion of the line selection, HiCAD automatically switches to the selection of the axis.

Select the rotation axis as follows:

• Planar sketches
  Determine the stretching centre via a point specification. If this point is located outside of the sketch, it will be projected onto the sketch plane.
• 3-D sketches
  Select the rotation axis by
• specifying two points,
• selecting an edge, or
• selecting a plane. The rotation axis will be the surface normal.

You have the additional option to right-click and open a context menu with further functions for direction specification.

Enter the rotation angle. Rotation axis and direction will be dynamically visualized in the drawing. To change the axis click on the symbol and select the new direction as described above.

Top rotate the selected lines/points - as shown in the preview - click OK or Apply.

If you select Apply, the dialogue window will remain open after performing the rotation. Only the list of the selected elements will be deleted in the process, all other settings will be preserved and cannot be changed. In this way, further elements can be rotated in the same way.

If you select OK, the dialogue window will be closed after the rotation.

If you middle-click in the drawing while the dialogue window is open, the following will happen:

• If enough value inputs have been made, the function will be executed. The dialogue window will remain open (same as with Apply).
• If the value inputs are insufficient, HiCAD will jump to the next required selection. For instance, if you have chosen the line to be rotated and then press the middle mouse button, HiCAD will jump to the selection of the axis.

A: Rotate lines individually, B: Preserve connected lines and adjust length

(1) Selected lines, (2) Select centre of rotation, Angle 45°, (3) Result

(1) 3-D sketch; (2) Highlighting of selected elements; (3) Selection of a surface, Angle 90°; (4) Result without adjustment of connected lines

Please note:

• Instead of clicking Apply in the dialogue window, you can also press the middle mouse button (MMB) to apply the rotation.
• The selected lines and isolated points must belong to the same sketch. Otherwise, a corresponding error message will be displayed.
• HCM constraints will be adjusted if possible. If an adjustment is not possible, they will be removed.
• If, after clicking Apply, a renewed selection of lines / isolated points leads to a conflict with an already selected rotation axis, it will be deleted and needs to be selected anew.
