 643 QCAD (main)Feature RequestLow Zooming mode of operation Closed
100%
Task Description

I just realized, that Zoom-in and Zoom-out (with the mousewheel) works different from graphical editors I know (as soon as drawing is larger than full screen).

Graphical editor (PSP X2 (and other too I think)):
Will make the position of the cursor the center of the drawing area. Thus allowing very fast to reposition the viewable area without changing into a move mode (Hand icon) and without the rulers on the left or down of the drawing area. The reposition is very handsome!
But this solution is only half way practical: If you use the wheel twice to zoom twice in sequence without moving the cursor, it will reposition the image twice - this double reposition is not practical at all, as the second reposition is rather random!

QCAD:
Lets the center unchanged and just zooms-in or Zooms-out.
.

My proposal:
- Zoom-in or Zoom-out around the current position of the cursor
- move this current position to the center of the screen
- move the cursor itself to the center of the screen (thus avoiding to shift the image again with a subsequent zoom-operation

  1. if the user uses a second zoom-op the new center remains mostly fixed. This would allow best of both solutions:
  2. but the user is free to make an other area of the drawing the new center if he actively moves the cursor again.

I think this would be very simple, intuitive and efficient to handle, reducing the need to reposition the drawing manually a lot.

Actually I think earlier version of graphical editors I used worked with were implemented that way.

Caveat:
I’m not an extensive CAD user. Maybe there are special requests for this type of work that are in contradiction to my idea. Maybe it would be practical to activate this type of zooming when used along with <ALT>. Hmmm - no: Allow original QCAD-zooming with <ALT>!

.

By the way:
Mouse right-click seems never assigned in QCAD. In Windows a user usually expects ‘Properties’ to be activated with right-click. But I think with the clever way you implemented this, there is no real need to change this. As the standard is already broken: Why not assign permanently a ‘Move’ (Hand icon) to ‘right-click’...

 642 DocumentationBug ReportLow Better explanaton for Layer '0' Closed
100%
Task Description

Layer ‘0’ has some special function. E.g. it can not be deleted, it will contain the data of undeleted layers.

I recommend adding some explanations: Explain the function of Layer ‘0’ as third paragraph in chapter 12 of the manual. Further it should be recommended to never use this layer for drawing.

By the way: I consider this to be better than no layer undelete. BUT: is there really not way for a true layer undelete...

641QCAD (main)Bug ReportLowNo warning is displayed when lengthen tool is used with...Assigned

Task Description

Command ‘Lengthen LE’ will extend most arcs but not all (2 arcs in the attached drawing do not work)! There is no obvious reason for this from the users point of view.

 640 QCAD (main)Bug ReportLow Selected object dos not get printed Closed
100%
Task Description

If an object is selected while ‘print preview’ is activated this object will be shown in preview in a special color and not printed at all.

I do see no reason for either behavior. My opinion: If it gets saved while selected it should get printed as well.
