To close an unnecessary selection set variable, set it to nilĪutoLISP - Using SSNAME in Selection Sets - YouTub If this limit is reached, AutoCAD cannot create any more selection sets and returns nil to all ssget calls. Selection sets consume AutoCAD temporary file slots, so AutoLISP is not permitted to have more than 128 open at one time.Command: (setq EN1 (ssname SS1 0)) This gets the first object in the selection set The index position numbering begins at 0. Explanation: the (ssname) function (ssname selection_set position) The selection_set is a selection set and the position is the location of the object you want to process within the set.In this chapter, each listing contains a brief description of the function's use and a function syntax statement showing the order and the type of arguments. The following is a catalog of the AutoLISP ® functions available in AutoCAD ®. AutoLISP Reference Guide: AutoLISP Functions.String-Handling Functions Reference (AutoLISP) Related Reference. Example (substr abcde 2) bcde (substr abcde 2 1) b (substr abcde 3 2) cd Related Concepts. This differs from other functions that process elements of a list (like nth and ssname) that count the first element as 0.

The following example code shows calls to ssname: (setq sset (ssget)) Prompts the user to create a selection set

Finally, the function ssname returns the name of a particular entity in a selection set, using an index to the set (entities in a selection set are numbered from 0).

Ssname - AutoCad AutoLISP Functions Documentatio But when I do (ssname ss1 1) it results in nil How can this be? Shouldn't this always result in an. Janmaat schreef in bericht Hi, I have a selectionset wich consists of 22 entity's.

(entget (ssname ss1 1)) results in nil (ssname ss1 0) (ssname ss1 1) (ssname ss1 2) And so on.

This video will show you how to use SSNAME Selection Set Function in AutoCAD using AutoLISP.This is one of the section of the full course on udemy Practical.Get the name of the first entity in a selection set: Command: (setq ent1 (ssname ss 0) If index is negative or greater than the highest-numbered entity in the selection set, ssname returns nil. Subentities (attributes and polyline vertices) are not returned ssname (AutoLISP) Returns the object (entity) name of the indexed element of a selection set (ssname ss index) Entity names in selection sets obtained with ssget are always names of main entities.In this case the lead architect works in ArchiCAD, but we as Contruction Managers have only AutoCAD, so everytime we get files from them there is a lot of information in those files that is wasted, because we can not read it properly, so we have to waste hours on retracing polylines to be able to double check the information we have received.Home Autocad lisp ssname ssname (AutoLISP) - Autodes Some thoughts: This real life situation is a clear case that shows how format incompatibilities makes us waste a lot of time. The polylines will be generated on the current layer, and properties. This routine when used, allows you to select as many Hatch Patterns as you want and obtain their boundaries in the form of polylines. The solution was found via DigitalCAD, in the form of a LISP routine called HATCHB.LSP.

The problem came becuase there were a lot of this AEC_SPACE objects,and AutoCAD does not allow to regenerate boundaries of multiple Hatch Patterns at the same time. The solution for a single AEC_SPACE, was simple, explode it, regenerate the boundary of the Hatch Pattern, and select the resulting Polyline to see the area (or to extract the area to an excel file as explained on a previous post). Unfortunately, plain AutoCAD doesn't read the are of this objects, and by exploding them, it generated Hatch Patters that would not show their area on the properties palette. I had to work on some files converted from ArchiCAD to AutoCAD and needed to use the AEC Space entities to get the areas. Do you need to re-generate the boundaries of multiple hatch patterns? An AutoLISP routine will do it.
