The ssget function returns nil if none of the selected entities match the specified filtering criteria. Otherwise, the entity is not included in the selection set.

#Autocad lisp assoc 8 code#

If an entity's properties match all specified fields in the filtering list, it is included in the returned selection set. Here's the code I have in the lisp which I copied from the thread. The ssget function filters a selection set by scanning the selected entities and comparing the fields of each main entity against the specified filtering list. This type of test performs a Boolean вЂњANDвЂќ operation. This code selects only Circle objects on layer FLOOR3 that are colored green. If the filter-list specifies more than one property, an entity is included in the selection set only if it matches all specified conditions, as in the following example code: (ssget 'X' (list (cons 0 'CIRCLE')(cons 8 lay_name)(cons 62 3))) (setq d1 (assoc 8 b1)) Gets the sublist code 8. (setq b1 (entget (ssname a1 index))) This gets the entity list and assigns it to 'b1'. (repeat n This begins the loop that pages through the selection set. Select the required file and click the 'Load' button and click the 'Close' button. I suggest that you go through this tutorial along with the AutoCAD. Next to вЂLook inвЂ™, click to browse to the directory where you have saved the lisp file. This tutorial is aimed at the AutoCAD users who would like to start learning AutoLISP. The Load/Unload Applications dialog box will be displayed. For example, the following code creates a selection set of all objects in the database that are on layer FLOOR3: (setq lay_name 'FLOOR3') (setq d2 (assoc 8 b2)) This looks for the code 8 in the entity list 'a2', and then assigns the sub list to 'd2'. Start your CAD program and at the command prompt or on the screen, type 'appload'. If either is specified by a variable, the list must be constructed using the list and cons function. ATTRIB) (assoc 8 AEL) layer (cons 2 TAG) tag name (cons 10 base point (mapcar + determined by adding IP insert point to (cdr (assoc 10 AEL)))). AutoLISP is one of a number of Application Programming Interfaces (APIs) built into AutoCAD but it is probably the easiest to use and therefore the most productive for the beginner.

If both the group code and the desired value are known, the list may be quoted as shown previously. AutoLISP is a programming language designed specifically for use with the full version of AutoCAD (i.e. use the assoc function to extract a particular dotted pair: Command: (assoc 8. Note that this filter picks up lines that have been assigned color 5 (blue), but not blue lines that have had their color applied by the ByLayer or ByBlock properties. 'AcDbLine') (10 3.0 5.0 0.0) (11 6.0 6.0 0.0) (210 0.0. Prompts for general object selection but adds only text objects to the selection set.Д¬reates a selection set containing all line objects from the last selection set created.Д¬reates a selection set of all objects inside the window that are also on layer FLOOR9.Д¬reates a selection set of all objects in the database that are Circle objects.Д¬reates a selection set of all blue Line objects that are part of the Implied selection set (those objects selected while the AutoCAD PICKFIRST system variable is in effect).
