Transformation Editor Tools Dialog

The Transformation Editor dialog is used for many types of transformation operations including: global transformations, camera transformations, tool transformations, and others. Tool transformations are described in this section of the documentation.

Tool positions...

Opens the Transformation Editor dialog which allows you to precisely position the various tools within the Graphics Window in reference to the selected Frame.

Tools → Tool Positions...

Region Tool (Selection region)

Click Editor Function in the Transformation Editor dialog and then select Selecting Tools → Region Selector from the Editor Function Menu Bar to display the dialog shown below:

Figure 4.17: Transformation Editor (Select Region)

To precisely position the Selection tool, enter the desired normalized screen coordinate values for X and Y minimum and maximum. The coordinates can be between 0.0 and 1.0.

Tools → Tool Positions... → Tools → Select region.

Cursor Tool

Selecting Tools → Cursor from the Editor Function Menu Bar displays the dialog as shown in figure below. Additionally, right-clicking on the cursor tool itself in the graphics window and selecting Edit... from the Context Sensitive menu also displays this dialog.

Figure 4.18: Transformation Editor (Cursor)

The Transformation Editor dialog provides three methods for the precise positioning of the Cursor Tool. First, the Cursor Tool may be positioned within the Graphics Window by entering coordinates in the X, Y, and Z fields. Pressing Return causes the Cursor Tool to relocate to the specified coordinates in the selected Frame (or, if more than one Frame is selected, for Frame 0).

It is also possible to reposition the Cursor Tool from its present coordinate position by specific increments. The Axis button allows you to choose the axis of translation (X, Y, Z, or All). The Slider Bar at the top allows you to quickly choose the increment by which to move the position of the Cursor Tool. Dragging the slider in the negative (left) or positive (right) directions and then releasing it will cause the X, Y, and Z coordinate fields to increment as specified and the Cursor Tool to relocate to the new coordinates. The number specified in the Limit field of the Scale Settings area determines the negative (-) and positive (+) range of the slider. If the Limit is set to 1.0 as shown, then the numerical range of the slider bar will be -1 to +1.

Alternatively, you can specify an increment for translation in the Increment field of the Scale Settings area. Pressing Enter while the mouse pointer is in the Increment field will cause the Cursor Tool to translate along the specified axis (or all axes) by the increment specified.

Transformation Editor → Editor Function → Tools → Cursor.

See Use the Cursor (Point) Tool.

Line Tool

From the menu Tools → Line there are three options as shown in the figure below: Visible, Restrict drag to surface+normal, and Use positive surface normal.

Figure 4.19: Tools → Line Menu Options

Visible

Toggles the line tool visibility

Restrict drag to surface + normal

Locks line parallel to selected part’s surface normal. After choosing this option, click on the Pick icon and choose to pick plane tool location using surface pick + normal and then put the cursor tool on the part surface and pick using the P key and the line tool will appear aligned with the surface normal at the point picked with one end attached to the surface at the point of the picking.

Use positive surface normal

Locks line parallel to selected part’s surface normal in direction of surface normal. Therefore the same as above except the line tool will originate at the picked point location, but will be in the direction of the positive normal.

Selecting Tools → Line from the Editor Function menu bar displays the dialog as shown in the figure below. Additionally, right-clicking on the Line Tool in the graphics window and selecting Edit... from the Context Sensitive menu also displays this dialog.

Figure 4.20: Transformation Editor (Line Tool)

The Transformation Editor can control precisely the position and size of the line tool.

Position

The Transformation Editor dialog provides several methods for the precise positioning of the Line Tool. First, the Line Tool may be positioned within the Graphics Window by entering coordinates for the two endpoints in the X, Y, and Z fields. Pressing return after entering each coordinate value causes the Line Tool to relocate to the specified coordinates in the selected Frame (or if more than one Frame is selected, in Frame 0). Enter all three X, Y, Z fields for a endpoint and then press return once to cause the line tool to update its position to that endpoint.

You can also specify the node ID labels to use for the line endpoints.

It is also possible to reposition the Line Tool from its present coordinate position by specific increments. First click on the translate icon. The Axis button allows you to choose the axis of translation for the center of the line (X, Y, Z, or All). The Slider Bar at the top allows you to quickly choose the increment by which to move the position of the center point of the Line Tool. Dragging the slider in the negative (left) or positive (right) directions and then releasing it will cause the X, Y, and Z coordinate fields to increment as specified and the Line Tool to relocate to the new coordinates. The number specified in the Limit field of the Scale Settings area determines the negative (-) and positive (+) range of the slider. If the Limit is set to 1.0 as shown, then the numerical range of the slider bar will be -1 to +1. The transformations are relative to the line tool axis system.

Alternatively, you can specify an increment for translation in the Increment field of the Scale Settings area. Pressing Enter while the mouse pointer is in the Increment field will cause the center point of the Line Tool to translate along the specified axis (or all axes) by the increment specified.

First click the rotate icon. Next, pick an axis about which to rotate. Next pick an increment and limit (in degrees) and slide the slider to rotate the plane.

First click the scale icon. Next pick an increment and limit and slide the slider to scale the line about its center, along its length.

Second, the Plane Tool may be positioned by entering in 3 node IDs representing 3 corners (assuming unique node IDs). Third, the Plane Tool may be positioned using the Algebraic Plane Equation. Finally, the Plane Tool may be positioned within the Graphics Window by entering coordinates for the three corners of the plane in the X, Y, and Z fields. Corner 1 is defined as the -X, -Y corner of the plane, Corner 2 is defined as the +X, -Y corner of the plane, and Corner 3 is defined as the +X, +Y corner of the plane. Pressing return causes the Plane Tool to relocate to the specified coordinates in the selected Frame (or if more than one Frame is selected, in Frame 0). For your convenience, you can enter values into all fields and then press return once to update the plane tool position.

You can also position the Plane Tool be entering the id for three nodes. The Plane Tool will then remain tied to these three nodes - even as the nodes move in a transient geometry model.

You can also position the Plane Tool by entering a plane equation in the form Ax + By + Cz = D in the four fields and then pressing Enter. For convenience, enter in all four then press return. The coefficients may then be normalized, but the equation of the plane will be the same as the one you entered. The coefficients of the plane equation are in reference to the selected Frame (or if more than one Frame is selected, to Frame 0).

As with the Cursor and Line Tools, it is possible to reposition the Plane Tool from its present coordinate position by specific increments. First click the translate icon at the top of the Transformation Editor. The Axis button allows you to choose the axis of translation (X, Y, Z, or All) for the origin of the Plane Tool (intersection of the axes).
