JamCAD Posted March 30, 2015 Share Posted March 30, 2015 Hi, I'm trying to use visual lisp to automate setting up viewports. The trouble is when I try to change the centre. As a basic example (setq entv (vlax-ename->vla-object (car (entsel)))) (vla-put-center entv '(500.0 200.0 0.0)) returns the following error: ; error: lisp value has no coercion to VARIANT with this type: (500.0 200.0 0.0) (vla-get-center entv) Returns: # Quote Link to comment Share on other sites More sharing options...
JamCAD Posted March 30, 2015 Author Share Posted March 30, 2015 vlax-make-safearray or vlax-make-variant? I haven't used either function before and couldn't get it to work. Quote Link to comment Share on other sites More sharing options...

Lee Mac Posted March 30, 2015 Share Posted March 30, 2015 FWIW, You can also omit the list format & z-value, e.g.: (vla-put-center entv (vlax-3D-point 500 200)) Quote Link to comment Share on other sites More sharing options...
