Like most software, MycadHELPER requires a short adjustment period while you become familiar with its approach. It introduces a more efficient way of working with CAD, and at first you may be surprised by how little input is actually required when the system is used effectively. This will involve some adjustment from your usual workflow.

One of the most distinctive features is MycadKEYS—a highly streamlined, keyboard-driven command system for creating and editing drawings. Users who are accustomed to mouse-driven grahic menus may initially question this approach, but most quickly adapt and appreciate the significant reduction in keyboard use and menu navigation.

Although MycadKEYS can be used occasionally, it performs best when used consistently. You can always revert to standard CAD commands when needed, but if you allow yourself a few days to slow down and learn the system, you will likely find within a week that you no longer want to return to the traditional command interface.

First Steps

Begin by experimenting with simple tasks such as creating and editing objects. As you do this, focus on:

  • The reduced amount of input required
  • Enhanced object selection and snapping options
  • Opportunities to use the right mouse button

You may initially feel frustrated if you are used to pressing Enter to confirm each step. In MycadKEYS, most command options require only a single keystroke—no Enter key is needed unless you are entering a number or text.

With a little practice, you will quickly adapt to the smoother, faster workflow.

Command Names

MycadKEYS uses a logical naming system based on functional groups, making commands easier to learn and remember:

  • Editing commands often use single keys
    • Example: C = Copy, M = Move
  • Object creation commands use two characters
    • Example: PL = Place Line, PA = Place Arc
  • Other grouped commands follow consistent patterns
    • Example:
      • JF = Join Fillet
      • JT = Join Trim
      • QA = Query Area
      • QO = Query Object

As you become familiar with the structure, you will often be able to guess command names and functions, even for commands you haven’t used before.

Command Prompts

As in standard CAD systems, the command line displays prompts for the next action. MycadHELPER extends this by providing additional options and explanatory notes directly in the command area.

Typical responses to prompts include:

  • Selecting objects
  • Picking or entering a point
  • Entering a value
  • Accepting a default
  • Choosing a command option

Many commands offer multiple default options, which can be selected using:

  • Spacebar (most common)
  • Enter
  • Tab
  • Backspace

Keep an eye on the command line, as it will indicate the available choices.

Keyboard and Mouse Use

Unlike traditional CAD aliases limited to alphabet keys, MycadKEYS uses nearly the entire keyboard, including numbers and symbols. This expands the available command set to over 50 options.

Non alphabet keyboard characters are used in intuitive ways, for example:

  • | relates to line types
  • $ relates to styles
  • @ relates to attributes

Both mouse buttons are used:

  • Left-click for selection
  • Right-click for alternate selections, sub-entities, or default options

Because the right mouse button often has a specific function, it is not always available as a simple Enter substitute.

Drawing Environment

MycadHELPER is flexible, but it reflects proven workflows developed by experienced CAD professionals. Following these conventions will give the best results.

Recommended Settings

For optimal performance, the following standards are recommended:

  • Use 3–4 command lines for better visibility
  • Avoid setting OBJECT properties BYOBJECT e.g. Colour, Line-type etc
  • Define object prioerties BYLAYER, Create layers instead of overriding object properties
  • Use layer “0” within most blocks
  • Use text styles with zero height for flexibility
  • Avoid manually resizing MTEXT where possible

Additional Best Practices

  • Use on-the-fly OSNAPs rather than preset ones
  • Define block attributes as PRESET
  • Use structured layer naming (SHORT or MED if using MycadLAYERS)
  • Work in decimal units (some tools may not function correctly in imperial)
  • Use a dark background for clarity
  • Draw in Model Space at 1:1 scale
  • Plot from Paper Space (strongly recommended)

Notes

  • The system is currently optimised for a US keyboard
  • Some key mappings may differ on other keyboards
  • AutoCAD’s dynamic dragging is limited in AutoLISP, but MycadHELPER provides alternatives
  • Standard AutoCAD commands can still be accessed by prefixing with a hyphen (e.g. -C)

Learning MycadKEYS Shortcuts

Commands are grouped by function, making them easier to learn progressively. Start with the commands most relevant to your work, particularly object creation and editing.

Frequently Used Commands

Many commonly used commands are assigned single keys, including:

Copy, Move, Rotate, Text, Zoom, Layer, Xref, and more.

Object Creation (Prefix “P”)

Examples include:

  • PA – Place Arc
  • PL – Place Line
  • PC – Place Circle

Joining Commands (Prefix “J”)

Examples include:

  • JE – Join Extend
  • JF – Join Fillet
  • JH – Join Heal

File Commands

Examples include:

  • FG – purGe
  • FP – Print
  • FU – Utilities

Enquiry Commands (Prefix “Q”)

Examples include:

  • QA – Area
  • QB – Block-name
  • QC – Colour

View Commands (Prefix “V”)

Includes tools for:

  • View control
  • Camera
  • Grid
  • Draw order

Workspace Commands

These commands adapt depending on whether you are in Model Space or Paper Space, including:

  • Mview
  • Vplayer
  • Vclip

Be aware of the distinction between standard AutoCAD WorkSPACE and MycadHELPER WorkZONE.

Final Note

MycadHELPER is under continuous development. If you encounter unexpected behaviour or work outside the recommended setup, updates or adjustments may be required. Feedback is always valuable and helps improve the system.
