Send entity "to back"...

[Anonymous]

Dear all,

Did anybody invent anything smarter for sending selected entity "to back"
than using plain SendCommand? What mechanism does it use? What part of DWG
keeps track of "what's above what" and what layer is the bottomost? I'm
writing a TLB using VB and any sort of SendCommand seems quite ugly and
quite out-of-process... you know what I mean...

Thanks in advance for possible tips,
Maksim Sestic

Hello,
I believe the draw order is determined by the order in which the objects are created. Another option is to copy the items you want in front and then delete them.

Lorier,

I was just curious about internals
of DRAWORDER command, as I can't any smart substitution for it. If I copy
objects then I'm changing their handlers, so it's not the solution I'm looking
for.

Regards,

how do you do it with send command? I thought there was no way to change the
display order from VBA at all.

I don't understand what you are trying to do.

The SendCommand is used to send things to the AutoCAD command line, such as
a "hide" command.

Since AutoCAD is a 3D program you can change the elevation of certian
objects with
the .Elevation property or just change the Z coordinates of the object to
move it above
or below another object.

While modifying the elevation may be a workaround in most cases, you
must be sure to reset the elev back to zero or you will cause other
problems. The point to the question is how come the ability to define
display order is missing from the api when it is available thru the
AutoCAD gui?

As I posted earlier, use the unsupported library ADSKUnSupp2000 for 2000
to 2002 and ADSKUnSupp2004 for 2004. This is better than the
sendcommand. Tony T's ACADX may do it as well.

Phil,

I was just trying to figure out how DRAWORDER command functions internally.
It's possible to use SendCommand to perform the draworder and send the
(previously created) selection set "to back" or "to front", neverthless of
how selected objects' layers are initially ordered. Alas, there's no exposed
object functionality regarding draworder... nor any hint of how ACAD stores
implemented drawing order of objects within the drawing... I guess Mike's
answer (ADSKUnSupp library) will do the job right.

Thanks,
Maksim Sestic
