COMMAND NAMES
Names of commands can be one of the biggest problems facing both CAD users and programers. Autocad has something like 700 commands and a similar number of system variables and as the programs become more sophisticated with time this number keeps growing. Many of the names are quite long and complex BAUTHORPALETTECLOSE others quite simple COPY.
Although no more than about twenty commands are used regularly, one hundred from time to time and the rest rarely if at all nevertheless the problem is how to identify and issue these commands to the program. Learning the commands is the best option but Command MENUS have become the standard solution with both graphic and text input options but both suffer from the problems of user distraction, search, recognition and selection.
Originally direct text entry at the command line was the only method of input. Most advanced users believe that it is still the best method; particularly since the introduction of short command aliases. It is the ONLY method that provides every command.
If one accepts command aliases as the way forward then the next problem that arises is how to create aliases for in excess of 1500 commands. (including system variables (settings) now treated by Autocad as regular commands).
Autocad and other CAD programs provide lists of aliases but these rarely cover all commands (quite reasonably so when one considers potential frequency of use). The problem with these program supplied aliases is that they evolved over time and being largely abbreviations of the commands are unstructured, frequently quite long and often provide little or no advantage over the full command word.
MYCADKEYS has been deliberately designed to manage almost every command (including variables) in a structured and logical way never using more than two characters for common commands or three for complex or rare commands. Single character aliases are reserved for the most commonly used editing commands. Only occasionally will you find a MYCADKEYS alias overwriting a program alias. If there is a rare clash of aliases then re-type the MYCADKEYS alias prefixed with a grave accent (back-quote “`”).
MYCADKEYS aliases access many improved versions of the commands so in order to use a generic command a user must type the full command name or program alias at the command prompt or, if available, select from a graphical menu.
Please note that although MYCADKEYS aliases have been defined for virtually every command some aliases are not yet functional due to the large number of infrequently used commands. (work in progress). Most programs that have not even provided a full list of aliases. In this case select the wanted command in the normal way from a menu or type its name at the command prompt. Undefined aliases will be activated upon request.
Back to BAUTHORPALETTECLOSE – Block Edit authOr Palette close - MYCADKEYS alias “BEOP-” Autocad does not provide an alias. (why the E for Edit? - for consistency, since BE is alias for Block Edit.)
MYCADKEYS assumes NOUN–VERB order rather than VERB–NOUN i.e. COPY-select-objects rather than SELECT- objects Copy.
The best aliases are naturally single characters but how does one create the over 900 aliases provided by MYCADKEYS (or even the 650 required by AutoCAD) with an average of two and never more than three characters from 50+ keys?
Have a look at the easy reference lookup tables that display Aliases to Commands and Commands to Aliases. The list is being constantly updated as new commands appear.
The majority of commonly used commands have a MYCADKEYS functional improvement such that C for Copy (no grave accent) starts an improved version of the COPY command while `C starts the generic command. Many custom MYCADKEYS commands execute functions not available in generic Autocad. There are many MYCADKEYS extended commands such as EL for Erase Last such that one can type EL<enter> for Erase Last or E<enter>L to achieve the same effect. There are also many MYCADKEYS commands that do not have generic command equivalents particularly with regard to OVERLAY drafting and WORKZONES.
Most common editing commands are single character such as C Copy, E Erase.
The majority of MYCADKEYS aliases are two characters such as:
-
Place Line (PL) Place Arc (PA) or
-
Join Fillet (JF) Join Trim (JT)
-
Query Area (QA) Query Layer (QL).
Thus you can see that by inventing a few new command words for groups such as Place, Join and Query a very large number of commands can be given recognizable two character aliases. Thus one and two character aliases are available for just about every command that you will commonly use.
An interesting group of commands are those that change the properties of things thus G for chanGe results in the Command line prompt. e.g. GC chanGe Color
(uppercase names indicate generic commands)
`G CHANGE/`GP CHPROP/`GP# PROPERTIES/`GP*/MATCHPROP/<<point/orthopoint>> /Clr/Elv/Fld/Grph/thK/#lngth/|ltype/ltype%scale/Mledit/Obj/Pline/Rad/Txt/Xtrd/Wdth/Lyr
Some MYCADKEYS commands include a command option such as Change Layer hence GL and this function can be extended by adding a further option such as Color hence GLC chanGe Layer Color.
One of the more interesting compound aliases that you will come upon when you get into MYCADLAYERS is GFC chanGe Field Color that chanGes the Color Field in a MYCADLAYERS Layer name (while at the same time chanGing the Color of the Layer.
So let's have a look at the command groups and see how the aliases are generated.
Complex Objects:
Dimension, Text, Leader, Mleader Attribute, Hatch, Bhatch. Insert, Attach, Overlay, Mesh, Table
There is a whole bunch of commands related to Text so they are grouped under T thus just about every command related to Text can be initiated with a two character command alias. e.g. TJ Text Justify
`T TEXT/Auto/Bounds/Dtext/brK/Case/File/Ht/Incr/Just/Ldr/Mtxt/Rot/Spell/$tyle/Upd/sWap/=settings/<<ldr/no-ldr
3D objects: e.g. 3DB 3DBox
Box/Cone/Cylinder/Mesh/Poly/Sphere/Helix/Polysolid/Pface/Region/Rulesurf/Solid/Tabsurf

COMMAND GROUPS
Drawing commands:
Simple Objects:
Command aliases for all simple objects such as Lines, Arcs and Circles use a command prefix P for Place such that PA means Place Arc, PL means Place Line.
The command alias P by itself initiates a Place command with options thus:
?/<<Qikik/3d/Arc/Bdry/Circ/Donut/Elipse/Face/Helix/sKetch/Line/Mline/Node/Offset/pGon/Pline/sYmbol/Rect/revcloUd/Surf-or-Solid/Trace/Wiggle/Xline/Zigzag/ALTMENU:>
You will notice a number of additional options to those provided by generic AutoCAD such as <<Qikpik; an Autolisp function that will draw a selected object possessing the same properties of Color Layer etc.
You will also notice when you start to draw something a prompt different from the generic AutoCAD prompt thus:
PL <enter> or other MYCADKEYS draw command produces an extended range of Object-Snaps.
OSNAPS: <:undo/App/Cen/noD/End/From/Gmid/Home/Int/Kwik/parL/Mid/Nea/Per/Qua/inS/Tan/Xval/Yval/Zval/|ine
From point: <repeat>/[done]/<<point/OSNAP/kwiksnap>> NON:
For example Gmid seeks the General midpoint between two further specified points while Jmid seeks the midpoint between the ends of two lines.
