Hi,
I would like to create versions of existing linetypes in the icad.lin file.

1) Which controls, the shown example or the line of code below the name/example line? Or do they work with each other?

2) What is the syntax of the line of code? (I have a guess, but I'd like to hear from those with more knowledge on the subject than me LOL)

Thank you,
Su

Hi Su,

In the icad.lin file, both the shown example (visual representation) and the line of code below the name/example work togethersnow rider 3d The visual representation helps you understand how the linetype will appear, while the line of code defines the actual parameters and properties of the linetype.

The syntax for a linetype definition in the .lin file generally looks like this:
Here’s a breakdown of the components:

*<LinetypeName>: The name of the linetype.
<Description>: A brief description of the linetype.
A, <Pattern>, <Spacing>, ...: Defines the pattern of the linetype. A stands for "Line" or "Arc" segment. The <Pattern> is a series of values where each value represents a length of a line or space in the linetype pattern.
For example: This defines a dashed line with a pattern where each dash is 1 unit long, separated by a space of 0.5 units.

When working with the icad.lin file (or any LIN file) to create custom linetypes in CAD software like IntelliCAD, AutoCAD, or others, the format and the way the linetypes are defined are crucial. Here's how it works:

Understanding the LIN File Structure
A LIN file defines linetypes using slice master two lines per linetype:

• Name/Description Line: This line starts with an asterisk (*) followed by the linetype name and a description.

• Pattern Definition Line: This line contains the code that defines the pattern, specifying the lengths of dashes, gaps, and dots.

The example provided is just a demonstration of the linetype, while the line of code below it is the actual definition of the linetype. They work together to show how the linetype will look and behave head soccer unblocked

1. Example of Line: This is typically a visual representation of the linetype. It shows how the linetype will appear when used in a drawing. strands hint
Line of Code: This line defines the actual properties of the linetype, such as the pattern, scale, and any other parameters.

To create versions of existing linetypes in the `icad.lin` file, the code under the name line defines the linetype pattern, while the name line serves as an identifier. The syntax for a basic linetype definition includes the name, a description, and the pattern code (e.g., `A,1.0,-1.0` for a dashed line). Both the name and the pattern work together: the name is for reference, and the pattern dictates the visual appearance of the linetype.
