Map

Optimize and Repair

Choose this command in the Map menu to optimize (reduce) the size of the map file and repair damaged objects. With edit operations such as deleting objects, empty space is created in the map file. This function removes this empty space and therefore reduces the size of the map file.

When OCAD encounters damaged objects it tries to repair them. If this is not possible, they are deleted.

After the optimization the Optimization Result dialog box is displayed with the following information:

• File size before optimization in bytes.
• File size after optimization in bytes.
• Objects repaired
• Damaged objects deleted
• Spurious objects deleted: Spurious objects are objects which are not visible. These may be text objects with no text and no line, line objects with only one point, or area objects with only 2 points.
• Unsymbolized Objects
• Objects with Unknown Symbol
• Objects with Invalid Symbol Type

Set Scale and Coordinate System

Visit the Set Scale and Coordinate System page to get some information about this function.

Change Scale

Choose this command in the Map menu to change the scale of the map. The map is enlarged/reduced according to the new scale. The Change Scale dialog box is displayed, where the new scale can be entered.

Actual scale
This line shows the current scale of the map. Choose the Set Scale and Coordinate System command from the Map menu to set the current scale.
Setting the current scale with the Set Scale and Coordinate System function does not enlarge or reduce the map. It only changes a number in the map file.

New scale
Enter here the desired new scale of the map. You may choose one of the predefined scales or enter the scale on the keyboard.

Enlarge/reduce symbols
Check this box to enlarge/reduce the symbols with the same factor as the map. When the box is checked, the map is enlarged/reduced like a photographic enlargement. When this box is not checked, the map is enlarged/reduced, but the symbols are kept in the same dimension.

Click the OK button to finish.

Create Map Grid

Choose this command from the Map menu to create grid lines on the map (e.g. it can be used to draw Magnetic North lines or the grid for a Name Index.). The Create Map Grid dialog box is displayed.

Now, you have to make the following adjustments:

• Easting offset: Enter the easting offset to the defined map grid for the vertical grid lines.
• Northing offset: Enter the northing offset to the defined map grid for the horizontal grid lines.
• Create vertical grid lines: Check this option to create vertical grid lines and enter the distance .
• Create horizontal grid lines: Check this option to create horizontal grid lines and enter the distance .
• Angle: OCAD uses the real world angle.
• Create vertices at grid junctions: Check this option to create a vertex at every grid junction.
• Symbols:
  • Grid lines: Select a line symbol for the grid lines (map grid).
  • Grid labels: Select a text symbol for the grid labels.

Click the OK button when finished. The grid is drawn over the whole map. Therefore, remove background maps which are larger than the map before creating a grid.
Create Name Index is the corresponding function to create a name index based on a rectangular map grid. The minimum and maximum grid line distance depends on the map grid distance. You can change this grid distance in Set Scale and Coordinate System dialog.

An imported layer can be converted manually. Visit the Convert a Layer Manually page to get more information.

Convert Area or Line Objects to Point Objects

Choose this function in the Map menu to convert area or line objects to point objects. This command is enabled if an area or line object is selected.

1. Select a line or an area object.
2. The Convert Area or Line Objects to Point Objects dialog appears.

   

3. Choose a point symbol.
4. Click the Execute button. The selected area or line object is converted to a point symbol and the chosen symbol is assigned to it.

The point symbol appears in the middle of the area or the line.

Convert Text Objects to Point Objects

Choose this command from the Map menu to convert text to point objects. The Convert Text Objects to Point Objects dialog appears.

This function is used after import map drawn in DTP program. In a DTP program point symbols are often drawn with a character and a special symbol fonts. OCAD can convert this characters to a point symbol.

In the first part of the dialog you can decide wheter you want to convert the objects from all text symbols or only objects from a selected symbol.

In the second part of the dialog box you can create a list of references. A reference consists of a layer and the corresponding OCAD symbol. You can save the list to a cross reference (.crt) file for later use. You can load an existing cross reference file to modify or execute it.

Visit the Cross Reference Table page to get some information about CRT-Files and the CRT-File part in the dialog.

Example of crt file:

 312.000 A
 313.000 B
 314.000 C

Click the Execute button when you are finished with editing the CRT-File. The conversion gets executed.

Convert Text Objects from OEM to Unicode

Choose this command from the Map menu to convert text objects from OEM to Unicode.

This function can be used after importing geodata from non-Unicode compatible programs or open ocd files from older OCAD versions. OCAD 11 is Unicode compatible.

In the first part of the dialog you can decide wheter you want to convert the text from all text symbols or only objects from a selected symbol.

In the second part of the dialog box you can create a list of references. A reference consists of a layer and the corresponding OCAD symbol. You can save the list to a cross reference (.crt) file for later use. You can load an existing cross reference file to modify or execute it.

Visit the Cross Reference Table page to get some information about CRT-Files and the CRT-File part in the dialog.

Click the Execute button when you are finished with editing the CRT-File. The conversion gets executed.

Example: After opening OCAD 7 file in OCAD 11 file some characters are invisible (e.g. the character Ť from codepage Windows-1250 to represent texts in Central European and Eastern European languages). Use this function to convert this character from OEM code '141' to the Unicode '356'.
