Selection and Zoom question

Jorge Mora

Hi every body

as you know, when we want to select various entities in briscad we need only to do a selection window and if we need to do a zoom view to complete the selection, it doesn't matter, because briscad will select the elements that will be touched by the selection window, it doesn't matter if we do a zoom in or any kind of zoom view.

in AUTOCAD, is different, because this one only selects the elements in the current view area. I have a friend that is using bricscad in this moment and "I don't know why" he wants the same mode of selection from Autocad in Bricscad, for me it's better the selection way of bricscad, but he want to configure the selection as Autocad.

is there some way to do this?

thanks a lot

The Autocad behaviour has already been introduces for the Lisp function (ssget).
Bricscad V12 Release Notes:
SR26208 SR26415 SR27730 - LISP/SDS:
(ssget "W") and (ssget "C") : object selection needs to be restricted to screen area (not selecting objects from offscreen area of given selection window)

I don't think there is setting to apply this behaviour to 'normal' user selection windows and crossings. If Bricscad goes for compatibility here I hope it will be switchable because I agree that the current BC behaviour makes more sense.

As far as I can see there is no difference between Autocad and Bricscad regarding the use of a selection window. Depending on the direction the mouse is moved a 'window inside' or 'window overlap' selection mode is applied. If you move the mouse to the left 'window overlap' is used, move to the right for 'window inside'. The fill color of the selection window (green = overlap; blue = inside) indicates the selection mode.

Louis, the OP is talking about performing a zoom function once a selection window has been started and how this differs from autocad; not that the selection window operates differently.  In autocad once you start a selection you can't zoom or the function resets where as in BC it remembers the starting point.  Please note I am just rephrasing as I'm not sure if this is the case or not.  Please correct me if I am misinterpreting

This is indeed the current situation. In Bricscad it is still possible to select offscreen entities manually. For example if you draw a circle, then pan it offscreen, and then type select, with coordinates of a window that includes the circle , the offscreen circle can be selected. Or if you start a selection window, then pan the circle offscreen, and then complete the selection window to include the circle, then again the circle will be selected. We haven't felt the need to modify this behaviour.

Good god, there can't reasonably be a discussion to re-implement each and every AutoCAD limitation...

Personally I like the way the selection includes off screen entities and I make use of it regularly. I understand the question is asking for a compatibility option. I really hope this ability would not be given up to remain.

thanks everybody for your comments

very good conversation, now I continue having in mind that bricscad selection way it is better, I enjoy to use bricscad really.
