inventor 2008 dwg
inventor 2008 dwg
i am trying to visualize a dwg made with inventor 2008.
the visualization is not corrected cause the fact that proxy entity is made from autodesk.
what can be made in order to correctly visualize the dwg with your lib?
if it is not possible hour, could be possible in a future?

i don't see anyway to access the 'acidblockreference" proxy type. i think 'acadpart' (sat solids data) is the only proxy we can really handle with dwgdirect.
autodesk's dwgviewer shows no entities in model space, but there is a layout in paper space.
actually you may implement acidblockreference as a custom object derived from acdbblockreference, with no members overloaded, except rtti. that will allow you to see inside the blocks at least.

vladimir,
i have never tried to make a custom entity using dd. so that i don't miss annything, is this procedure shown in one of the sample source files?
yes, see \examples\excustobjs\excustentity.cpp
vladimir
i have found the activator for acad 200x at the site
this works naturally only for autocad.
in order to make the same thing with dd lib as it can be made?
thoughts that can be made in future?
>thoughts that can be made in future?
if there would be sufficient demand.
send your request to support.
agitate for it on the forum.
vladimir
i just ran into this same problem from a customer of mine. all the entities in the file are proxies of class = "acidblockreference".
i'm not having much luck trying to make a custom entity to handle it.
has anyone out there tried it?
oops i forgot to attach the files.

simplest implementation of the acidblockreference looks like this:
code:
#include "dbblockreference.h"
#include "dbfiler.h"
class odidblockreference : public oddbblockreference
{
oddbobjectid m_pvportid;
public:
oddb_declare_members(odidblockreference);
odidblockreference(){};
virtual odresult dwginfields(oddbdwgfiler* pfiler)
{
oddbblockreference::dwginfields(pfiler);
m_pvportid = pfiler->rdsoftpointerid();
return eok;
}
virtual void dwgoutfields(oddbdwgfiler* pfiler) const
{
oddbblockreference::dwgoutfields(pfiler);
pfiler->wrsoftpointerid(m_pvportid);
}
// worlddraw && vportdraw should be implemented
};
odrx_define_members(odidblockreference, // classname
oddbblockreference, // parentclass
dbobject_constr, // docreate
oddb::vac21, // dwgver
oddb::kmrelease1, // maintver
1, // nproxyflags
l"acidblockreference", // dwg class name
l"acidblockreference", // dxfname
l"acidviewobj|product: inventor drawing enabler|company: autodesk|website: www.autodesk.com") // appname(the trick was to guess that acidblockreference stores that additional data - viewport reference)
to display it correctly though, one should implement viewport draw, that draws only into given viewport.
vladimir
vladimir,
thank you - that should help. i will let you know.
worlddraw && viewportdraw may look like this:
code:
bool worlddraw(odgiworlddraw* pwd) const
{
if (m_pvportid.isvalid())
return false;
else
return oddbblockreference::worlddraw(pwd);
}
void viewportdraw(odgiviewportdraw* pviewportdraw) const
{
assertreadenabled();
if (oddbobjectid(pviewportdraw->viewportobjectid()) != m_pvportid)
return;
oddbblocktablerecordptr pbr = blocktablerecord().openobject();
if (!pbr.isnull())
{
odgigeometry& geom = pviewportdraw->geometry();
odgematrix3d matrix = blocktransform();
odgepoint3d basept(pbr->origin());
matrix *= odgematrix3d::translation(odgepoint3d::korigin - basept);
matrix.validatezero(odgetol(1e-20));
geom.pushmodeltransform(matrix);
geom.draw(pbr);
geom.popmodeltransform();
}
}(attributes and spatial filters are skipped)
vladimir
great!
but before i even get that far, i need to get past this...
else if(pent->isa() == oddbproxyentity::desc())
{
oddbproxyentityptr pproxy = pent;
odstring proxyclass = pproxy->originalclassname();
if(proxyclass.compare("acidblockreference") == 0)
{
// the following obviously will not work, but how can i get to the 'blockreference' members and functions?
odidblockreference *pidblkref = odidblockreference::cast(pent);
oddbblockreferenceptr pblkref = pidblkref;
:
:
}
you should not analyze the class yourself. the class should be registered, and handled as normal class, not proxy. to do that, put
code:
odidblockreference::rxinit();somewhere in the application start, after odinitialize, and
code:
odidblockreference::rxuninit();somewhere before oduninitialize.
vladimir

now i get it!!!!
excellent!!!!
it's working!!!
thanks - i appreciate your help (in case you cannot tell that from all the "!!!!")
