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!
Right click on the view and set tangent lines to be removed.
Other option is to edit the flat pattern feature in the model and make sure merge faces is selected.
