![]() You must have at least two dash specifications for A-type alignment. The second dash length should be less than 0 if you need a pen-up segment and more than 0 if you are creating a continuous linetype. Between the starting and ending dashes, the pattern dash specifications are drawn sequentially, beginning with the second dash specification and restarting the pattern with the first dash specification when required.Ī-type alignment requires that the first dash length be 0 or greater (a pen-down segment). When the linetype is drawn, the application uses the first pattern descriptor for the starting and ending dashes. You need to include only one complete repetition of the linetype pattern defined by pattern descriptors. You can enter up to 12 dash-length specifications per linetype, provided they fit on one 80-character line in the LIN file. A negative decimal number denotes a pen-up (space) segment of that length.A positive decimal number denotes a pen-down (dash) segment of that length.Pattern DescriptorsĮach pattern descriptor field specifies the length of segments making up the linetype, separated by commas (no spaces are allowed): For circles and other objects without endpoints, the dash-dot sequence is adjusted to provide a reasonable display. For arcs, the pattern is adjusted so that dashes are drawn at the endpoints. If a line is too short to hold even one dash-dot sequence, a continuous line between the endpoints is drawn. If necessary, the first and last dashes are lengthened. The pattern fits the line so that at least half of the first dash begins and ends the line. The program adjusts the dash-dot sequence on an individual line so that dashes and line endpoints coincide. You must specify A-type alignment by entering A in the alignment field.įor example, suppose you create a linetype called CENTRAL that displays the repeating dash-dot sequence commonly used as a centerline. ![]() The program supports only A-type alignment, which guarantees that the endpoints of lines and arcs start and stop with a dash. The alignment field specifies the action for pattern alignment at the ends of individual lines, circles, and arcs. A description cannot exceed 47 characters. If you omit the description, do not insert a comma after the linetype name. A comment such as "Use this linetype for hidden lines".An expanded description of the linetype.A simple representation of the linetype pattern using ASCII text.The description is optional and can include The description is also displayed in the Linetype Manager and in the Load or Reload Linetypes dialog box. The description of the linetype should help you visualize the linetype when you edit the LIN file. The linetype name field must begin with an asterisk (*) and should provide a unique, descriptive name for the linetype. LIN files must be saved in the ASCII format and use a. The linetype would be displayed as shown below. This pattern continues for the length of the line, ending with a dash 0.5 drawing units long. The example indicates a repeating pattern starting with a dash 0.5 drawing units long, a space 0.25 drawing units long, a dot, and another space 0.25 drawing units long. If this also doesn't help, you should consider a Repair installation.The format of the linetype definition is * linetype_name, descriptionįor example, a linetype called DASHDOT is defined as *DASHDOT,Dash dot _. If this doesn't help reset your ACAD to the standard settings (WIN-key -> Programs -> Autodesk -> your AutoCAD -> Reset settings). If this all doesn't help, then start ACAD with an other or better a new profile. hardware acceleration ON/OFF and others). Pay with different graphic settings (e.g. The following example shows how you can use the Line By Direction and Distance command to draw a line from the endpoint of a previously drawn line, at a bearing of N 18° 02 E, at a distance of 11.0 feet. Let us know the values of the following System variables: Is your last drawn line listet? Maybe you draw on an invisilble layer? Now activate the Properties Window (Ctrl+1) and tell/show us what you see in the Properties window. If this was done (also if you don't see the line), start the select command, answer with L ENTER ENTER. So we can exclude that the Zoom factor causes the problem 4', then try to draw line nearby with a length of 4' and show us what you see. And why you don't answer our questions? Where is the content of the Text Window, which asked for? Why you didn't turn off ORTHO mode (and maybe other drawing helps) as I suggested? It is not sure that this solves your problem, but maybe so we could exclude some possible causes. Why you don't use the Snipping Tool (included in the Operating System of your computer) and show us a pic of your complete application window? We don't know what the dottetd lines at your pic are, we cannot see your UCS icon, we can not see your current settings in the symbol bar. We can't look at your monitor and your fingers. But you must also be a bit more cooperative.
