Scaling a Surface

You can scale a surface along one axis.

1. Click Modification .

2. Click Affinity .

   A 3D box appears around the selection.

3. Click the surface to position the manipulators depending on the mouse cursor position.

4. Move the mouse cursor to highlight the desired axis.

5. Hold the left-mouse button and drag one of the axes to affine the elements.

   You can see that the scaling value is displayed. Thus you have complete control on how much to scale a surface. Depending on the state of the Show Coord icon in the Help Text toolbar, the scaling value can be viewed in the following modes:

   
   

   • : the scaling value is viewed on the selected manipulator. This is the default state.

     
     
     

   • : the scaling value is viewed on the mouse pointer.

     
     
     

   • : the scaling value of the translation is not displayed.

     
     
     

6. Release the left-mouse button when you are satisfied with the new position of the surface.

You can scale a surface along two axes.

1. Click Modification .

2. Click Affinity .

   A 3D box appears around the selection.

3. Click the surface to position the manipulators depending on the mouse cursor position.

4. Move the mouse cursor to highlight the desired axis.

5. Select the arc of circle.

6. Hold the left-mouse button and move the mouse to affine the elements.

   Depending on the state of the Show Coord icon in Help Text toolbar, the scaling value can be viewed in the above mentioned modes.

   
   
   

7. Release the left-mouse button when you are satisfied with the new position of the surface.

You can scale a surface along three axes.

1. Click Modification .

2. Click Affinity .

   A 3D box appears around the selection.

3. Click the surface to position the manipulators depending on the mouse cursor position.

4. Move the mouse cursor to highlight the desired axis.

5. Press the Ctrl key.

6. Hold the left-mouse button and move the mouse to affine the elements.

   Depending on the state of the Show Coord icon in the Help Text toolbar, the scaling value can be viewed in the above mentioned modes.

   
   
   

   Tip: You can select any axis or handle: the scaling will still be performed along the three axes.

7. Release the left-mouse button when you are satisfied with the new position of the surface. The surface can now look like this:

   Important: The dimension corresponding to the selected manipulator is highlighted during scaling. You can see that in case of a scaling along one axis, a single dimension is highlighted. In case of a scaling along two axes, two dimensions are highlighted, while three dimensions are highlighted in case of a scaling along three axes. Thus, it is easy for you to identify the dimension being changed and track its value.
