Previewing Hidden Lines
If your assembly drawing has z-values assigned to its faces, you can preview the drawing to see how it will look after you generate hidden lines.
This preview mode redraws your assembly drawing on the screen, removing those lines that will later be generated as hidden.
The preview mode does not compute hidden lines, change the structure of the assembly or alter geometry. It only affects the view.
 |
HIDD DRAW affects all WINDOW functions as each takes the z-value information into account. You cannot use display lists (Displ List On in WINDOW) together with hidden line preview mode in the same viewport.
|
To preview your assembly drawing before you actually generate hidden lines:
1. Click 2DHL
2. Click HIDD DRAW
3. Select the viewport
Creo Elements/Direct 2D Access displays the drawing partially covered (depending on the z-values associated with the assembly drawing).
Note that Creo Elements/Direct 2D Access displays -H- in the upper left-hand corner to indicate hidden mode.

|
If you try to plot your drawing while in the preview mode, Creo Elements/Direct 2D Access will plot the normal drawing, not the hidden line view you see on your screen.
|
To view your drawing the way it normally looks without previewing hidden lines, use the NORM DRAW command. This is the default mode. To redraw normally:
1. Pick 2DHL.
2. Pick NORM DRAW.
3. Identify the appropriate viewport.
Creo Elements/Direct 2D Access redraws your assembly drawing the way it normally looks, without hidden lines displayed.
