Text Entities changing to MText Entities when writing to AutoCAD

I am working on an AutoCAD to AutoCAD conversion where I am changing the text of text and Mtext objects and writing out the changes. The AutoCAD writer uses the input file as a template as the only parts I want to change are the text elements (whether text/mtext/attributes in a block).

 

I am having a problem where Text entities (autocad_entity = autocad_text) are being written as MText entities in the output which is effecting the positioning of the text. This is happening for all text entities (autocad_text), where I have and haven't made changes

 

Is there any reason why text entities would be written as Mtext, when they are clearly defined as text entities in FME? I have posted some images of before and after below for reference:

OK this is a bit of a long shot but...

 

I found this in the doc for "autocad_true_type_font":

 

"The name of the TrueType font used to display the text string.

For text entities, this attribute is only used by the AutoCAD writer, since single-line text entities do not have support for TrueType fonts.

If this attribute is specified on an autocad_text feature, a multiline text entity will be created and written instead of a single-line text entity."

 

In your screen shot it looks like the "autocad_true_type_font" is set to null - Maybe try any use a NullAttributeMapper to map it to missing to see if that helps.

 

Regardless I suspect somewhere in there is a parameter which is cuaing these text features to get converted - it's just a case of hunting it down...

Try the DWGEntitySetter custom transformer from the hub.

All that does I think is set the "autocad_entity" attribute - in this case the attribute is already set correctly. It looks like the writer is doing some extra stuff somewhere to overrule this format attribute

@virtualcitymatt​ thank you so much, mapping the "autocad_true_type_font" from null to missing worked!

Ahh great stuff - silly that a value of null is enough to break it here. maybe someone at safe can add a ticket to the system to have this fixed or something. @andreaatsafe​ ?

 

At least there is a work around for this
