Dim settings problem.. dimblk & dimldrblk

Anonymous · ‎12-21-2008

I've been trying to find a way to set these two settings in .NET.. but
to no avail..

they request the "objectid" of the block being used.. but I cant figure
out how to get it.. (i've tried the getobject method in the block table
but it does not work..)

the settings I want to use are:

DIMBLK - Architectural Tick ("_Archtick" by default in the help files)
DIMLDRBLK - Closed filled ("." by default in the help files)

Can anyone shed some light on this problem?

The basic problem is that you're not familiar enough with
the API at the most basic levels (e.g., getting the Objectid
of a block given its name is a fairly basic concept).

If this is a learning exercise, you're getting ahead of yourself
and should probably try something simpler (like inserting a
block in the drawing, which also requires you to do the basic
lookup of the block's ObjectId). You can find a lot of code
here that shows how to get the ObjectId of a block. There
may also be some code in the API samples, but I can't say
for sure.

The short and skinny is that you have to open the block
table using GetObject(), and then call its Has() method
to see if the block exists. If it does, then you use:

blockTableObject[blockname];

which returns the ObjectId of the block whose name is
given as blockname.

I have already done the simple (like inserting a block). my problem
here (from what i can see) is that i don't KNOW the block names...? All
I can get from the help files is what to enter to get default values
(they don't give the "names").

I've even tried to extract the names from the preset values of existing
dimstyles (that didn't work either.. or perhaps i did that wrong)

as to the Has() method.. we know the block exists (as it's the default
setting for AutoCAD), so that does not help me at all..

How are you trying to set the Variables? SetSystemVariable?

Anonymous · ‎12-30-2008

In a stock AutoCAD drawing from acad.dwt, there is no block assigned to DIMBLK or DIMLDRBLK, and their values in the default 'Standard' dimstyle are ObjectId.Null.

If you are creating a new dimstyle, and want to use an existing dimension style as a 'template' (just as AutoCAD's DIMSTYLE dialog does), then you open the DimStyleTableRecord for the existing style you want to use as a template, and copy the values of its properties to the corresponding properties of the new dimstyle.

So, you have to get the existing DimStyleTableRecord for the existing style that uses the blocks that you want to use in the new style, and use those values, and you don't need to know their names to start with.

ok, after a lot more testing I finally have it working.. IF that
setting has already been used in the target drawing..

My problem now is that I need a way of setting dimblk to "_ArchTick" in
a drawing that has never had it used.. suggestions?

Setting the DIMBLK system variable, or the property of a DIMSTYLE?

Given that is what i'm trying to do.. (in the dimstyle record object)...

If the block already exists in the drawing, you just need
to get its ObjectId, by opening the block table and using
the indexer:

blockTableObject["_ArchTick"];

If the block is not in the drawing, you have to insert it.

I was hoping there was a way of making AutoCAD do that on it's own..
given it's just "another setting" for dimstyles (one that comes with
cad)..

But I guess not.

Just put the block in the template you use to start with.

That would be the "nice" solution, but the primary reason for wanting
this particular functionality is so it can be run in drawings that are
not of our creation. But I have since found a nice little snippet of
code (provided in the .NET book I have) that imports the required block
(after a little tweaking).

Thank you for the help.
