AW: Re: [Qgis-user] CAD funtions plugin

[Ziegler Stefan]

Hi Piotr
 
I'm already working on number 3. Number 2 is a bit more surveying stuff
but I also would like to see it in QGIS. For this tool there should be
also an import function for some common data formats (e.g. GSI etc.
etc.). And perhaps a function to take the mean if you measure the same
point twice. Ah and some 2D helmert if the station point is unknown.
 
Definitely too many new layers. I will try to store all the new objects
in a cadtools point or line layer. 
 
Thanks for your input.
 
regards
Stefan

   Hello Stefan,
   I am very happy that you add some  CAD  functions do Qgis.
   They are really useful, but still I feel lack of another CAD funtions
   in Qgis.
   What I really need is:
   
   1. Adding new objects entering coordinates (in point, line or polygon
   layer) just from keybord.
   2. Polar measuremets: we have station point, reference point and we
   enter distance and angle to  get coordinates of calculated point.
   3. Rectangular measurements (sometimes still useful): we have station
   point, reference point and we enter 2 distances (abscissa, ordinate)
   to get coordinates of calculated point.
   4. Intersection from 2 points when you know two angles to set point
   (in your plugin there is arc intersection when you know 2 distances
   to set point).
   5. Reverse intersection from 3 points (based on distances or angles).
   First 3 points a really important.
   What do you think about it ?
   
   As to functionality of your plugin now each new created intersection
   (orthogonal) point or line is on new layer. It is bothering when I
   want to further use a group of new created objects.
   
   So I would suggest:
   1. Add some setting options, where user may point out (enter name of)
   only 2 layers (point layer and line layer) where objects are written
   (with intersection or orthogonal  line and point). 
   2. Or second solution: to make editable in the same time 2 layers
   (with points and lines) and to add new objects (intersection or
   orthogonal lines and points) at these editable layers.
    
   Regards,
   Piotr

      Hi 

      I started working on a plugin that provides some CAD functions:

      1. Intersections of linesegments (that do not intersect)
      2. Arc Intersection
      3. Orthogonal digitizing

      I added another function to the plugin: 
      
      4. Orthogonal Line: draw an orthogonal line from a point to a line
      segment.
