I was wondering if the options enumerated below are available in the latest version of Blender (which is 2.75a at this moment). Due to my 2d and 3d CAD background, the efficiency, effectiveness and obviousness of such options in programs and the fact I like Blender, I am sometimes urged to seek out such options in Blender to get the job done. There may be an option or two not necessarily in such CAD software, and still desirable to have due to its increasing of work speed.
Enumeration:
- if the pointing/mouse cursor is hovering over the 3d cursor, then, after a proper set time, visual selection, grabbing and manipulation of the 3d cursor’s position (and the 3d cursor) is allowed and possible (with some sort of good visual cue to prompt the user that the option is available to use with Mouse Select)
- if the view is simply in 3d, whether Perspective or not (and not set specifically orthogonally (i.e., the side, the top, etc.)), you can still properly draw lines with the Knife tool and its Angle Constraint option as if the view were specifically set to actually, e.g., draw straight lines parallel to some axis (…the way it is now, from what I’ve seen, you must have a specific view set orthogonally to use the constraint option as obviously intended by a user in such a case)
- Extend: extend geometry until a given line/border
- Trim: cut off geometry at/until a given line/border
- Circular Array
Now I use so-called workarounds to get certain things done. For example, if I want to cut symmetrically, I use the Knife tool and measure exactly or I use a piece of new and mirrored geometry to cut the object to be cut.
