I do hope that Marco finds the time though to provide a QEP.

Hello Andreas,

There is an ongoing development to implement curves for display and

plan is to release it in either 2.8 or 2.10.
Would'nt this typically be the kind of change which would require a 
QEP ?


It would be great to have one before the actual implementation, so that
potential design problems or impacts on other parts of the code (or 
plugins)

are detected.

Thanks,

If you have interest in curve support in other data formats (Oracle, 
SQL

server, dxf, etc.) you are very welcome to support/sponsor the effort.

Hi Vincent

A QEP about geometry refactoring is in work and the draft will be 
published very soon (today or tomorrow).

Re: [Qgis-user] QGIS curve looking lines not viewable

[Explorer]

Thanks for the response. Is there any other way to convert the existing
Oracle data type to something else which can then be rendered in QGIS?
   Curious, curves are quite common in map data, so how does all others use
QGIS then ?!

Thanks for your time.

Re: [Qgis-user] QGIS curve looking lines not viewable

[Andreas Neumann]

Hi,

Curves (circular arcs) are not yet supported in QGIS.

There is an ongoing development to implement curves for display and 
editing, but in its first incarnation it will only support Postgis data 
sources. There may also be support for GML/WFS (but I am not sure). The 
plan is to release it in either 2.8 or 2.10.


If you have interest in curve support in other data formats (Oracle, SQL 
server, dxf, etc.) you are very welcome to support/sponsor the effort.
