Shift for a change


SHIFT FOR A CHANGE

Howdy. It's been a while. With 3 kids in sports and a full time job, there's not much time left for blogging!

This week's (month's ?)  topic, the Shift key.

Did you know there is a whole other world of commands available by just holding down the shift key?

Here's a quick list to get you started.

- Shift + Right mouse button will bring up your OSNAPs during editing commands providing your Right Click options are set accordingly in Options > User Preferences > Right-click Customization.  See below.

These are not the default preferences, but they are what I think most people prefer, particularly us 'old timers'. Experiment to see what you like.





- Shift + Left mouse button will remove objects from your selection set providing you are selecting the objects before issuing a command (Noun/Verb mode). In otherwords, select a bunch of objects so you see their grips, then Shift+Left click on things to remove them from your selection set.  


TIP: Once in a while "Shift to add" option may have been changed. So if you find that when you pick on objects, the first object picked gets unpicked, take a look a Options > Selection and make sure Shift to Add is not selected. See below.





- If you want to FILLET or CHAMFER with a 0 distance, start the FILLET or CHAMFER command, pick your first line, hold down shift and pick the second line. It will fillet with a 0 radius without changing the radius you may have previously set.



- If you hold down SHIFT while using Trim or Extend it will perform the opposite command, so you can issue the TRIM command, trim a few lines, then hold down shift and when you pick lines, they will EXTEND to the 'trim' line.



- Shift + Middle mouse button (wheel) will do one of two things:



1. Hold Shift then Middle mouse button (wheel) and you will start a 3D orbit around your model as you move your mouse.



2. Hold Middle mouse button then hold Shift and you will Pan orthogonally vertical or horizontal when you move your mouse. I really like this when panning in viewports.


Kind of Unrelated TIP: To pan in viewports by a specific amount, use the -pan command line. For instance, in an unlocked viewport type -pan, pick a point, move the cursor a bit and just type in the amount you want to pan. This is great for plan and profiles if you're a civil kinda' person.


You can customize shift, ctrl, and alt clicks in the CUI as well. So, if you have a 5 or more button mouse, you can have all sorts of commands available at your fingertips. Literally.


----------------


Shift in plain ol' Windows does some neat stuff too.


For instance pick on a file in Windows Explorer, Shift+Right click and you can select "copy as path". This is a great way to email someone in your company where a file is located on the network. This option is not available in the regular Right Click menu.


To sum things up:
It doesn't hurt to right click or shift + right click to see what happens. Even Ctrl+right click and Alt+right click do different things. Experiment! It doesn't hurt anything, and there's always Undo if it does! You just may want to save first though. ;-) As a coworker of mine always says, "When in doubt, right click it out."


Well, gotta get ready for a soccer game and lacrosse practice... see ya.

AutoCAD's Align command


 ALIGN


AutoCAD's ALIGN Command.
Frequently overlooked or just unknown to many users.

Become familiar with the ALIGN command to line up 2d and 3d objects.

It works great for surveys and aerial photography. It is a move/rotate/scale command all wrapped up into one.

Type ALIGN (or of course pick it from the Modify menu or Ribbon) then select the object or objects to move. Pick a point from the object to move and then a point where that first point should be moved to. Repeat again and maybe a third time for 3D objects. Answer the command line prompt if you want the objects scaled or not and viola! you've just moved, rotated and optionally scaled something in one fell swoop.



This is a great tool to line up scanned drawings to get them to scale.

A word of caution:
If aligning a drawing or image or other 2D object in a drawing that contains 3D objects, be careful if you are snapping to things so you don't align the 2D object onto some unwanted 3D plane.
