How to Fix ProgeCAD Copy Paste Line Type Issue (LTSCALE)

If the line type changes after copying objects from one drawing to another in ProgeCAD, the problem is usually caused by different LTSCALE values between the two drawings.

This is a common issue when working with multiple DWG files. Fortunately, it can be fixed in just a few steps.

Why Does This Happen?

Every drawing stores its own line type scale using the LTSCALE system variable. If the source drawing and destination drawing use different values, dashed, dotted, or hidden lines may appear differently after pasting.

How to Fix the Line Type Issue

Step 1: Check the Source Drawing

  1. Open the original drawing.
  2. Type LTSCALE in the command line.
  3. Press Enter.
  4. Note the displayed value.

Step 2: Check the Destination Drawing

  1. Open the destination drawing.
  2. Type LTSCALE.
  3. Press Enter.
  4. Compare the value with the source drawing.

Step 3: Match the Values

If the values are different, change the destination drawing's LTSCALE to match the source drawing.

After changing the value, type: 

REGEN

or 

REGENALL

to refresh the drawing.

Additional Checks

  • Verify that the required line types are loaded.
  • Check PSLTSCALE if you are working in layouts.
  • Confirm that annotation scales are consistent.
  • Ensure both drawings use compatible units.

Why This Solution Works

LTSCALE controls the global line type scale for a drawing. Matching this value between drawings ensures that dashed and hidden lines display consistently after copying or inserting objects.

Frequently Asked Questions

Why do dashed lines become continuous after copying?

This usually happens because the LTSCALE values are different between the two drawings.

What command should I use?

Use the LTSCALE command to check and modify the line type scale.

Do I need to restart ProgeCAD?

No. Running the REGEN or REGENALL command is normally sufficient.

Does this issue affect DWG compatibility?

No. It only affects how line types are displayed, not the DWG file itself.

Conclusion

If line types appear differently after copying objects between drawings, the first setting to verify is LTSCALE. Matching the LTSCALE values in both drawings and regenerating the drawing usually resolves the issue quickly.
