Effect:

An AutoCAD cartoon or some objects within information technology demand to be flattened because one or more than of the following is non working correctly:

  • Selecting objects.
  • Using OSNAPs (the marker jumps to the wrong place).
  • Using commands such every bit TRIM, EXTEND, HATCH, FILLET, Join.
  • Measurements or dimensioning for distance and angles.

Solution:

To flatten a drawing automatically in AutoCAD:

Employ the FLATTEN control to modify the Z values of all lines, arcs, and polylines to 0.

  1. Plough off or freeze whatever hatch layers with hatch patterns so they are not included in the selection.
  2. Blazon FLATTEN at the command line.
  3. Select all objects and press the Enter primal.
  4. Type N for No when prompted to remove hidden lines.

Notes:

  • FLATTEN requires Express Tools to be loaded.
  • Although it is possible to select and flatten everything in a drawing all at one time, it might be necessary to use the QSELECT command to select each group of object types and then run the FLATTEN command on them.

For 3D objects, apply the FLATSHOT or SOLPROF command to create 2nd views.

  • Replace the Z value For 3D objects in layout viewports.

    1. Enter OPTIONS in the command line.

    2. On the Drafting tab > Object snap options, check Replace Z value with electric current elevation.

To flatten a drawing manually or in AutoCAD LT:

  1. Open the Properties Palette in AutoCAD.
  2. Apply Quick Select or theQSELECT command to select objects by type (see Utilize Quick Select to select objects in your AutoCAD cartoon).
  3. In the Properties Palette, observe the values for Start Z, End Z and Heart Z (for certain shapes), change to any whole number other than0 (Zero) for each.
  4. Do the aforementioned except alter the value of each to 0 (Zero). (This fixes any values that are more than viii decimal places and non visible in the Backdrop Palette).
    Annotation: To utilize this method with certain objects such as blocks and groups, they must commencement be exploded.


Alternative to change the Z value of objects to nothing:

Use the CHANGE control:

  1. Type in theCHANGE command.
  2. Type ALL to select all objects and then Enter.
  3. Blazon P for Backdrop.
  4. Type E for Elevation.
  5. Type 0 and and so a final Enter to stop the command.

Note: This will not work on complex objects such as 3D objects.


To flatten a drawing using LISPs, macros, and scripts:

One or both of the post-obit LISP routines, pasted into the control line in AutoCAD, will flatten a drawing.

  • This command changes the superlative of all objects to naught:
            (command "_change""_all""""p""e""0""")
  • This control moves objects very high so back down to zero:
            (command "_move""_all""""""0,0,1e99""_move""_all""""""0,0,-1e99")

Macros may be assigned to CUI buttons AutoCAD and AutoCAD LT.

  • To flatten selected objects:
            ^C^C_UCS;;_select;\_move;_p;;0,0,1e99;;_move;_p;;0,0,-1e99;;
  • To flatten the entire drawing:
            ^C^C_UCS;;_move;_all;;0,0,1e99;;_move;_all;;0,0,-1e99;;

The Null file attached to this commodity is a script file that tin can be run in AutoCAD and AutoCAD LT. It volition remove the peak of all objects in the drawing.

How to utilize the SCRIPT (Command)

  1. Launch AutoCAD LT
  2. Open any working drawing
  3. At the command prompt type Script
  4. In the 'Select script file' dialog browse to and select the saved script file
  5. Select 'Open'
  6. The script will run through the commands.
  7. Salvage the drawing.

To flatten a cartoon via PDF or DXB export:

Do the following:

  1. Plot a PDF or DXB file.
  2. Import this file into a new or existing cartoon with PDFIMPORT. The geometry will be flattened.

Notes:

  • To create a DXB file, a DXB PC3 printer must first be created using the Add-A-Plotter Wizard. Enter the PLOTTERMANAGER control to open the folder that contains the wizard.
  • AutoCAD 2022 and to a higher place have the PDFIMPORT command.
  • The DXB plotter converts all color data to black and white and places all drawing geometry on layer 0.
  • A PDF will retain colour and layers as long equally a color plot manner is selected and the PDF layers options is selected when creating the PDF.

If objects are far from the origin (0,0,0), move objects closer to the origin.
