Wrong render result of 'Dimension pre-rendered block'

[Sululu666]

The problem is when open this file, some dimension part not display.
zhongwangpeixun1.zip

Here is the result:
1.by other product:

2.by dxf-viewer:

It took a while found that when not use dimension pre-rendered block,

those part will show:

(with wrong text as actualMeasurement of dimension not handle)

Question:
Is there any lack of judgement to decide whether use 'Dimension pre-rendered block', like the content integrity of block?
If it is because development is not complete, please ignore this issue.

Thanks for the report and sample file. I do not think the problem is in the pre-rendering block selection, most probably something in the block is not rendered properly for some reason (maybe not implemented). Rendering dimensions in fall-back path (without the block) is quite tricky and in most cases produces a result which is not identical to one in the CAD software (dimension rendering usually is very software-specific, that is probably the reason these blocks are introduced in DXF and used in most files). So will need to investigate why the block is not rendered correctly.

Thanks for the answer.
By the way, I've found that those pre-renderd blocks' color and colorIndex are both undefined
and for temporary test I set the color to 'byLayer.

then the render result is right:

hope this give you train of thought
