Tangent edges - how to hide in DXF export and flat-form view in drawing.

When viewing parts and/or assemblies I like to have the tangent edges turned on and visible for part clarity.

When exporting the flat-form to DXF however I do not want to see the tangent edges as it's a pain to continually delete them.

As well as viewing them in the flat-form view in the drawing, concerned only with brake center hit lines.

2018 version this worked but with 2019 I cannot set the defaults for this.

Any suggestions? Thanks in advance!
