block to label x y coordinates

I also believe you are confusing block attributes for some other term, as true attributes do not work in dynamic blocks in Bricscad or ACAD.

@Jason Bourhill:

I don't think this statement is correct. The drawing I attached to my earlier post has two dynamic blocks defined, each one includes attributes. This is what is used to display the X & Y coords.

I stand corrected my mistake...

Hi all,

I am facing similar problems with coordinate labeling. I want to label elevations (z from xyz)  from lines and points but I fail to do this with a block. In our company we have premade marker for labeling coordinates. They work well in AutoCAD 2010 and 2012, but do not work in BricsCAD v14. I've created an abstracted version of our marker with a point, and an attribute with a field. The attribute contains a field which references the point's Position property. I've created a block from the whole. When I now insert the block to a new place in the drawing the coordinates do not get updated.

I've tried using only fields and what not but I fail to achieve position labeling in BricsCAD. Does someone have a clue on how to achieve this functionality? I have attached my latest attempt in doing so to this post. There's a block named xyz which can be inserted at a position. while the reference point from the block has the correct coordinates it doesn't show them as expected.

Many thanks for your help,

Frank

For this situation you need to define a FIELD that is self referencing. i.e. it looks at the properties of the inserted block, not the original definition. Unfortunately BricsCAD doesn't provide a method to create these type of fields. If you look at your original drawing, the field definition looks something like

%<\AcObjProp Object(%<\_ObjId 611975616>%).Coordinates \f "%lu2%pr2%pt4">%

In the drawing attached (edited using AutoCAD), the field has been changed to the correct type
%<\AcObjProp.16.2 Object(%<\_ObjId 610149248>%,1).Coordinates \f "%lu2%pt4%pr2">%

The good news is that once the field has been created you can continue on and create the block with BricsCAD, and it will work! In the attached drawing I created another block definition (see the blocks with the added circle) using BricsCAD, and it worked without issue. Based on this I would think Bricsys only (small word, there maybe more involved) have to update the FIELD dialogue to allow use of this type of field.

Sorry for the double post, but there's no way to edit a post. At least I didn't find it. Anyway, another thing I noticed, which might be related, is when I use UPDATEFIELD. I have four of your blocks in my drawing. Here's the command flow:
[code]: _updatefield
Select field(s) to update: ALL
Entities in set: 4
Select field(s) to update:
<8 fields found, 4 updated>[/code]
Why are there 8 fields found? There are only four blocks, shouldn't there be no more than 4 fields in the drawing? Mysterious, mysterios

Hi Jason,

I feared already that this is something that is simply not working in v14. As a preliminary solution I can insert the Block, open up the Attribute Editor, edit the Field and select the Block as object using the blocks position as the data source. Then I can COPY this edited block around and it gets updated correctly. This works at least as an intermediate solution until we buy v15.

Thanks,

Frank

I have also been struggling with fields in attributes in blocks.
The AutoCAD defined blocks that I have been using in BricsCAD for about 2 years stopped working some months ago.

The basics of the (drawing title) block and the manually entered attribute values work,
but the attributes that are defined as fields (DWGNAME etc) stopped working.
The fields would display correctly in the original dwg file containing attribute definitions,
but when this was inserted as a block into another dwg file, there was no way to get the fields to update.
The fields stubbornly retained the values they had from the original dwg file.

I have just found a solution / workaround in an AutoCAD forum and the solution works for me in BricsCAD 16.2.09
The solution is to set the 'Constant' flag for the attribute containing the field to the value 'No'.
The disadvantage is that a careless user could overwrite the field value, but at least the fields update correctly.
