Press в†µ Enter or Esc when you are done scaling to close the Scale dialog box. This could be a folder in my documents, or you could use the supplied folder with Hammer.The scale changes will automatically be reflected on the selected object. You can press the up or down arrows to move in 0.1 increments, or enter a scale value directly in the text area. Change the Scale value to alter the selected points.Alter the center of the scale operation my clicking and dragging the white circle in the center of the vertex selection.Press Alt+ E to enter to bring up the Scale dialog box.Click on the vertices/edges you want to scale.Vertices will be marked as white dots, and edges as yellow dots. The selected solid will turn into a wireframe image with partial shading. Select the Vertex Tool from the MapTools Toolbar.Select the object(s) you would like to scale vertices on.Press в†µ Enter when you are done to close the Scale dialog box and return to normal vertex edit mode. Pressing the arrows in the Scale dialog box will increase or decrease the amount of scaling done on the selected vertices. Drag the circle in any of the 2D views to reposition it. The circle is used as the center of the scale operation. The Scale dialog will open, and a circle with a dot in the center will appear in the center of the selected vertices. Select the vertices you wish to scale and press Alt+ E. You can also perform vertex scaling with the Vertex Tool. If this happens, undo the split and try splitting it between the other two corners. This can generally be remedied by splitting the offending faces diagonally into triangles however, this can also cause the solid to become concave, which is also not allowed. If you need to create complex world geometry try to use multiple brushes instead of multiple face splits to create the shapes. This is an invalid solid, and while your map will compile with this error it will not run. This was created after the front face was split in half, followed by splitting the right half of the resulting face again. The solid appears correctly in the orthographic 2D views, but in 3D view a plane with 0 thickness is visible (highlighted in grey). Splitting a face multiple times (splitting a face that was generated after splitting another face) usually results in invalid solids being created. A resulting invalid solid after a multiple face split
