Generating Hidden Lines
Introduction to Hidden Lines
The 2D hidden line module is used during the creation of an assembly drawing to automatically generate lines that indicate hidden drawing features. In an assembly drawing, these lines are normally shown dashed.
To create an assembly drawing that includes hidden lines, you must:
• Load parts.
• Generate faces (without faces you cannot generate hidden lines).
• Assign each face a logical level in the z direction (a z-value).
• Use the z-value information to generate the appropriate hidden lines.
During the drawing process you can selectively view faces for clarity (ensure that each face is correctly positioned in relation to the others).
Use one of the following methods to redraw your assembly drawing with hidden lines:
• Click Hidden Mode and On — this mode effectively redraws your assembly drawing, hiding any hidden lines and faces.
• Click Hidden Mode and Off — this is the normal Creo Elements/Direct Drafting redraw mode.
On completion of your assembly drawing you can generate hidden lines in the dashed linetype (default).
 Click Backup in Change to Hidden to store your assembly drawing (in workfile.hid) before generating hidden lines. The Change to Hidden command smashes the parts structure and creates the hidden line geometry. |
Two tutorial examples have been included:
• A simple example using a Frame Assembly will clarify the general procedure.
• A realistic example creates a component assembly drawing (CRANK_ASSEMBLY).
