Topic: entmake or vla-addline

[curmudgeon]

From Afralisp,

"As the line was created from scratch, and created using Visual LISP functions, we already have a reference to the line Object (myLine). We can now safely run our reactor function and attach it to our Line."

It looks like there are some commands for the purpose of translating entities to objects, and back....
vlax-ename->vla-object
vlax-vla-object->ename

Is there reason for me to learn so many commands that seem to be "vl" specific?
Opinions solicited.

From my tests vla-addline works faster within BricsCAD but entmake within AutoCAD.

Learning those "VL" commands gives a better understanding of the object structure, which is much more important when dealing with other APIs such as dotNET.  Reading and changing properies can also be easier to follow - (vla-get-SomePropertName target_object) vs. (cdr (assoc DXF_ID (entget target_entity))).

Thanks guys. I believe I will take on the "vl" commands a little faster than as needed, but not much.
Confession: I am already addicted to vlsort.

Have a look at (vl-catch-all-apply ...) and (vl-catch-all-error-p ...).  Extremely handy, even when not directly dealing with VLISP functions.

And the vlax-curve-* functions make life a whole lot easier when working with polylines / splines / arcs. No need to have any trig (or at least very little) to get exactly what you want.

Those particular vl commands are now on my list(s).
Thank you.
