Q. vl-sort without removing (& a for loop question)

[SteveK]

Hey,

 

The first question (EDIT) was my mistake which ronjonp brought to light.

 

The second question I have is alternatives to for loops. I frequently have a list of entities/objects where I want to find objects with two or more particular properties. This I can achieve with a few for loops, one for each property but it seems messy. I was trying to think of other ways and I thought of using vl-position and this will work if there's only one object I'm after:

(setq obj (nth (vl-position '<something> (mapcar 'vla-get-<something> objlst)) objlst)

Have you got any better ways of finding multiple objects that have multiple properties in a list of objects?

 

Ofcourse the best alternative is the quickest. I'm assuming ssget is the quickest filter and I will use that initially.

Will this not work for you?

 

(vl-sort yourpointlist (function (lambda (x1 x2) (> (car x1) (car x2)))))

Hi, thanks for replying. Your right! I'm sorry my mistake, it is somewhere else in my code I am losing entities. I automatically assumed vl-sort was the culprit.

 

 

 

If anyone can help with my other question that'd be great.
