View

The commands on the View menu allow you to zoom in and zoom out on your drawing.  They also allow you to pan left, right, up and down.  Choose the File/Open command and select the file sample.gc1.  Choose the View/Zoom window command and pick positions 1 and 2 in the figure below, for the corners of the zoom window.  The program will zoom in on the selected area.  The entire area you selected is displayed as large as possible, as in the second figure.

Choose the View/Zoom previous command and the previous view is restored.  The last 10 views are saved and can be restored.

Choose the View/Zoom extents command.  The program will zoom the drawing so it is displayed as large as possible in the drawing area.  If you have drawing elements which extend beyond the edge of the current drawing area, selecting the Zoom extents command will change the view so all the elements are visible.

The View/Zoom page and extents command combines the Zoom page and Zoom extents commands.  The entire drawing and the page are displayed as large as possible in the drawing area.  This can be useful for positioning the drawing on the page, if your drawing currently extends beyond the page boundaries.  Positioning the drawing on the page is described in more detail in a later tutorial.  For this drawing, the Zoom page and Zoom page and extents commands produce the same result, since the drawing is entirely within the page.

The View/Redraw command simply redraws the drawing without changing the view.  This can be used to clean up the drawing area after editing.

This ends this tutorial.

Your view of the drawing should now look similar to the first figure below.  Select the View/Zoom factor command and enter a zoom factor of "0.5".  The view is zoomed out so the drawing appears to be half of its previous size, as in the second figure.  The center of the previous view remains in the center of the new view.

Choose the Zoom factor command and enter a value of "2."  The view is zoomed in so it appears to be twice as large as before, or the same size as when we started.  The view commands do not change the dimensions of the drawing, they just change your view of the drawing.  It is similar to zooming in and out with a camera.  When you zoom in, objects appear larger.  When you zoom out, objects appear smaller.  Of course, the actual size of the objects do not change.  You can think of the drawing area as your view finder.
