With this routine you will be able to insert in a selected axis polyline points with their respective distances, the data of the insertion of these points, come from the manual digitization of distances or the reading of a file of distances a file of example for a better understanding. This routine could be used for example in the case of the axis of a road , in some occasions it is necessary to locate an exact progressive in the axis polyline , like for example the progressive one If you have too many distances to enter the axis, instead of typing them lisp provides the option of selecting a text file , within this text file will be the distances and the lisp will read them one by one, inserting them by a point on the axis polyline.
The lisp also allows you to change the start of the axis since the start is determined according to the starting point that generated the polyline, if the lisp begins to put the distances by the end point that is not the desired, use the option: « Change axis start «. Along with the routine is a CAD file, with a simple axis polyline , as an example to implement the lisp routine. With this routine made with AutoLisp and VisualLisp, you can insert each "n" meters the dimensions of a selected polyline natural or vertical terrain in your profile format, the dimensions will be inserted taking as reference a point indicated in the format.
In this command you can define the scale of the drawing , this scale does not refer to the vertical scale of a profile, but to the scale of the texts of the dimensions to be inserted, the dimension texts for an 1: scale will be larger than those of an 1: 50 scale.
Another value to enter and the one that defines this command, is the distance in which the dimensions will be inserted , the default value that this routine brings is 10, which means that the dimensions will be inserted each 10 meters horizontally from the indicated reference point. Remember in order for the program to obtain the corresponding dimensions, the profile must be correctly located , ie the dimensions are correct for the profile. This routine developed in Autolisp and Visual Lisp, allows you to obtain the length or progressive of a polyline or axis and insert it into the drawing by means of an insertion point.
To do this you must select the polyline and indicate that the initial is progressive, you must verify that the command has obtained the starting point of the correct polyline start of axis , if not, you can change the start of the axis with the option that Presents this command to you. You can modify some default parameters from the source code, such as the height of the text to be inserted. Note that your coordinate system must be positive, otherwise an error will be generated by indicating the progressive point or length to be obtained.
If among all the numerical texts the command Find a non-numeric text For example, the word "point" will take this text as 0. To get the results alone It will be enough to select one by one or by means of a window Window the texts from which information is desired.
This routine allows you to scroll through all the layouts and print each of them with the current page configuration you have, it is worth clarifying that the layout of the model space will not be taken into account. The command runs through each of the layouts and if it verifies that it is the model space, it is skipped by continuing with the others, so if you want the model space to be printed, you only have to modify the command to Which is also taken into account and printed.
You can take advantage of the functionality of this command to, for example, insert letterheads, delete or add text in each layout, etc. If you have many files to print and each one has many layouts, you can increase the functionality of this command by:.
Create a file called Acad. LSP» ; This is the name of the attached file. The path is not indicated because it is understood that the path of the specified lsp file is added to the AutoCAD support directories indicated in the options dialog , otherwise the line of code can be replaced by the the full path of the lsp file to load is indicated :. This lisp routine allows you to trim selected texts, trim them to the right, left or both sides, that will depend on what the command is told.
Finally, if you tell the command to trim on both sides, 2 characters to the left and 3 to the right, the initial text will be replaced by «».
As you can see, just indicate the number of characters to cut and select the texts and these will be cut as indicated. Hello, I would like to know if you have any course or training to learn to program in Autocad. And also to create an app that helps me to count and identify a set of polylines.
I want to extract that information and show it in Excel. I am looking for lisp to make a gradient, that is to say with a circle of a certain radius, a contour curve must be cut and a polyline generated from the origin and so on as it moves to another place it is for the design of a road and is delinquent copy the circles and trace the polylines thanks.
They have some routine to assign attributes to basic elements, not blocks, and these can be visualized in a dialog box on the screen. Thank you so much. I'm from Cuba. Please could you tell me where I can download your lisp routine «Export Coordinate points to a CSV file» because I have the topography of an area and I need to export it to csv or txt the points are entered as text content is the dimension and in the coordinate Z comes out zero, got it?
Please could you help me. I would like the lisp with the function "Remove internal or external objects from a selected polyline", because in the article I cannot find the download link.
Hi, I would like to know if there is a routine to obtain the number of objects and place them in text. Additionally, in Not Found error was encountered while trying to use an ErrorDocument to handle the request. Hello sorry excuse me to help with a lisp to define a polyline with its km, I explain if I have a polyline with origin Dm of start and a dm of end , to be able to mark any point inside the polyline and I throw his dm and I leave stipulated.
If you could help me I would appreciate them as I work with this frequently and would be very useful in road projects. Greetings someone can help me with a lisp to be able to link a survey done with arbitrary coordinates starting from two points, then placed the original coordinates north and east and the quota left the same arbitaries from the two starting points for which I did With aling but quotas are changed. Greetings, Lola.
Good day, I would like to know if anyone knows any small routine or has some simple example of some small routine to create a dbf database and add data to it or delete from autolisp. I hope they help me. Thank you. Hello friends, I would like to know if anyone knows of a routine to measure the angles or external of a polygon and its distance and if it is not too much to ask them to export to Excel.
How do you write a. I want to export from civil 3d all cross sections generated to text files, I just need to show the mileage, the distance to the axis, and the corresponding level. Something like that. Let's see if I understood. You say that with your lisp you export the coordinates to Excel Have you put him at a distance? But if you already have the coordinates in Excel, why not make a next column with a formula of pythagoras between the point and the next?

Enter the name of the command: EL3 Selects the lines from which the starting and ending point coordinates will be exported. To import the points, it is considered necessary that the point file to be imported has XLS extension from versions prior to office or XLSX version or later And in the file the coordinates are formatted with the format: P, N, E, C, D, P together, N Orte, E ste C ota D Description , as shown in the following image: It allows you to choose among 3 different types of ways to insert a point object in the read coordinate.
The second option consists of select a block stored in the drawing As a point to insert in the read coordinate, by default the routine creates a new block called "cg-point", which can be used in the case that there are blocks or not in the drawing. The third option related to the style of point, Allows you to import a block from the hard disk , Remember that in this case the dimensions with which the block was created influence the visualization of the block at the time of insertion.
With regard to point data labels , iCe Lets you decide what you want to show , if you only want to display a Point, you will only have to select this option, the same for the text of the Dimension or the Description of the point.
You can choose to display the 3 tag data or not display any. Inline Feedbacks. Meet the Authors. Get Connected.

You should be aware that expressions can be nested, and that you evaluate them from the inside out. Others may include:. What else should a beginner know? Finally, you should know how to get help. Which leads us to the next section…. Control your AutoCAD environment. Not sure what your favorites add up to? No longer do you need to open the Object Snap dialog and check and uncheck boxes.
Almost any environment variable you can think of can be set this way. You can create your own keyboard short commands. If the value of variable a is the list 5 10 , then:.
This is the secondary command for taking a list apart. If the value of variable a is the list 2 5 7 9 11 , then:. This always produces the second element of a list. Assuming the value of variable a is the list 5 10 , then:.
This always produces the third element of a list. Assuming the value of variable a is the list 3 7 5 then:. Changes a string of text from lower case to upper case, leaving upper case characters as they are.
Returns a part of a string, from a specified position, ending either at the end or another specified position. For example, if a group of items is preceded by an apostrophe, it is treated as a list. Returns an angle between two points in radians. To use that angle in AutoCAD you have to convert it back to decimal degrees. But a is not the correct rotation angle because it is in radians. Returns the nth element in a list, where n is the number of the element to return.
Zero is the first element. Often used with the subst function; the assoc function lets you search for a specific element, then assign that element to a variable. Lets assume variable b is the list 10 5. You want to pull out the entire element and assign it to a variable c. This assigns the entire element containing the 40 in the list b to variable c.
Now c is a list that looks like this: 40 5. Allows you to substitute one aspect for another. Now lets substitute 20 for the 5 in the variable c.
The new element will look like this: 40 h. You need to construct a new variable containing the entire list element, then use the new variable in the subst function. Constructs a new list with the new element placed at the begining. Assume variable c contains the following list: 40 5. Also, assume variable h contains the real number Therefore, car c is the new first element, followed by the value of h.
Thus it produces a new list d 40 In the list found in variable b and assigns the new list to b1. Takes an angle in radians and converts it into a string, using a specific format. Angtos has two arguments, the first controls the format and the second controls the precision. This function returns the convertion of an integer to a real number. One can use either real or an integer.
In other words, it is not used to assign a value to a variable as it is in some other programming languages. AutoLisp uses the setq function to perform this task. In AutoLisp, the equals character is used to test if items are equal, it does not make them equal. This is very useful if we are trying to test certain conditions.
For example, we can begin to construct tests with an outcome such as "if one thing is equal to another thing, do something". That's what conditionals are all about; they allow your program to make decisions. If a is equal to b , then b will be assigned the value 5.
