===Technical Debt=== <!--T:26-->
The rapid pace of TechDraw development has left in its wake numerous "technical imperfections" that should be addressed. One of the biggest involves appearance related Properties which belong to Feature instead of the ViewProvider. This results in unneeded recomputes of the model when only a graphic update is really required.





Revision as of 12:47, 12 June 2018


The TechDraw workbench is new and hasn't had the years of development that have benefited some other workbenches. Still, TechDraw can now "produce basic technical drawings based on the 3D model".

Here is a rough roadmap of areas to be addressed in the future (in no particular order).

Current Activity

  • improve Dxf export compatibility with ACAD.
  • bug fixes.

Recent Changes

  • Export Pages and/or Views to Dxf file.
  • Reduced amount of recalculation when updating Properties.

Draft/Arch coexistence

There are inconsistencies between the way the Draft/Arch and TechDraw modules represent shapes. This limits the suitability of TechDraw for Draft/Arch users. One notable short-coming is that TechDraw is unable to apply Dimensions to the Svg images it receives from Draft/Arch.

Templates

Making a template with editable text fields requires significant expertise with Svg and an Svg editor like Inkscape. Making the template creation process simpler will be a priority in the v0.18 development cycle.

Drawing Tools

This includes the ability to add leaders, callouts and detail highlights to Views. It is a prerequisite to many enhancements, particularly in the drawing annotation area, such as feature control frames and reference highlights for detail views.

2D Geometry

A number of 2D geometry functions were recently added to the Part module. This needs to be reviewed with an eye towards replacing custom 2D geometry code in TechDraw with standard code from Part.

Internal View Consistency

It is not currently possible to create a Detail from a Section, or a Section from a Detail due to internal differences. Changes here would allow any View type to be a BaseView.

"non-Vertex" Dimensions

There is a need for Dimensions that do not rely on specific vertex/edges, but on extrema of the figure - for example, overall width/height. A related request is for an "arbitrary" measurement that can be added when an actual value can not be calculated automatically.

Bug Fixes/Feature Requests

See the bug tracker for up to date information.
