All these functions work for reading from and writing into text and binary files too. Only difference is in this case the stream we use is not standard input or output, but a stream created for the specific purpose of writing into or reading from files.
In this chapter we will see how LISP can create, open, close text or binary files for their data storage. A file represents a sequence of bytes, does not matter if it is a text file or binary file. You can use the open function to create a new file or to open an existing file. It is the most basic function for opening a file. However, the with-open-file is usually more convenient and more commonly used, as we will see later in this section. The latter method is preferable, because modification is easier.
If you save the following code as an acad. The acaddoc. This file is useful if you want to load a library of AutoLISP routines to be available every time you start a new drawing or open an existing drawing. Each time a drawing opens, AutoCAD searches the library path for an acaddoc. If it finds one, it loads the file into memory. Most users will have a single acaddoc. The program searches for an acaddoc.
Rotation point is the middle of the bounding box for Text, Mtext, and Tables. For blocks, the rotation point is the insertion point of the block. For the first two, the alignment direction is the X direction of the selected Coordinate System. Selecting 2Points will allow you to pick the alignment on screen. The lisp can be used to fix messy drawings, we got this requests from few clients each user will find the benefit of this Automation.

Go to the Autodesk Education Community. Choose AutoCAD. Create an Autodesk account. Alternatively, sign in to your existing Autodesk account. Yes, I know this because I got it wrong the first time! Assuming your certificate is visible, click on that line to select it. You can add files to the pane at the top left using the buttons on the right side or by simply dragging and dropping files onto the pane from Explorer.
But wait! Before you do that, make sure you have a safe unsigned copy of all your files.
