![]() if a valid selection set was generated, then proceed. prompt the user to select closed polylines set a reference to the current model space. create an empty list, set a counter variable, and The sample function 'scon' return a concatenation of first string variable and second string variable. (defun C:POLYTABLE ( / *MS* A CNT I LST MYTABLE PT1 ROW SSET TLST) These sizes used here work with the Standard tablestyle in a new empty drawing. The TABLE is creating on the current tablestyle, so depending on the settings of your current tablestyle, you may have to adjust the sizing arguments in the (vla-addTable…) function in order for the table to look acceptable. You could easily adapt this to show the layer, color or any other property. One containing the area, and the other containing the ObjectID. This routine allows the user to select closed polylines, and it will create a TABLE with two columns. This example also creates some FIELDS using lisp. Hope this helps you understand what might need to be changed with your custom programs and how you might go about making the change.Here is an example of creating a TABLE entity using lisp. (strcat (rtos (getvar "CDATE") 2 6)(substr ms (- (strlen ms) 2))) Get the current milliseconds and append it to the CDATE value Check to see which AutoCAd release is being used Returns a CDATE value that includes milliseconds based on release When you explicitly use a quoted string in AutoLISP, that value is known as a literal string or a string constant. Within quoted strings the backslash (\) character allows control characters (or escape codes) to be included. The function returns the value of the CDATE system variable when executed on AutoCAD 2016-based products and earlier, and returns a value that combines the values of the CDATE and MILLISECS system variables when executed on AutoCAD 2017. A string is a group of characters surrounded by quotation marks. The following is an example of a custom function named CDATE that returns the values of the MILLISECS and CDATE system variables based on the release of AutoCAD being used. However, if you are just tracking time differences, you might just want to migrate to using the MILLISECSsystem variable instead of the CDATE system variable. Using the MILLISECSsystem variable, you could get the last 2 or 3 digits of the value and append them to the value returned by the CDATE system variable if you want a value that is comparable to that returned in AutoCAD 2016-based products and earlier. The MILLISECSsystem variable returns the time difference in which the workstation was booted until now in milliseconds. When working with time intervals as small as milliseconds, consider looking at the MILLISECS system variable. If your custom programs do rely on milliseconds, chances are your custom programs might not be functioning as expected or could be taking longer than they did in previous releases if you are using a loop to wait for a detectable time change. ![]() If you are using these system variables, make sure your programs don't rely on time intervals as small as milliseconds. However, the CDATE system variables are also used to determine how long it takes for a custom program to run or to generate unique block names/entries in a log file. ![]() In AutoCAD 2017-based products, the CDATE and DATEsystem variables no longer store the current time down to the current millisecond which if you are getting the current date or time might not be a deal breaker for your custom programs.
