Welcome & Agenda Overview (5 minutes)

• Brief introduction to the session objectives and timeline.

Getting Started with 4MCAD (50 minutes)

• What Is 4MCAD? (10 minutes)

  • Overview of CAD philosophies and the distinguishing features of 4MCAD.

  • Discussion of typical use cases (architecture, engineering, product design).

• Interface Overview (15 minutes)

  • Ribbon Tabs: Home, Draw, Edit, Annotate.

  • Quick Access Toolbar: Save, Undo/Redo, Pan icons.

  • Drawing Window: Crosshair cursor, WCS icon, coordinate readout.

  • Status Bar Toggles: Snap, Grid, Model Space vs. Paper Space.

  • Model Space vs. Paper Space: When to use each and how they differ.

• Settings & Preferences (15 minutes)

  • Units & Precision: Format options and decimal display settings.

  • Dynamic Input: On-screen prompts for lengths and angles.

  • Grid & Snap Settings: Spacing, increments, and toggling.

  • World Coordinate System (WCS): Understanding and repositioning.

  • Autosave & File Folders: Setting the autosave interval and default directories.

• Navigation Tools (10 minutes)

  • Zoom Extents / Window: Quickly view all objects.

  • Pan: Move around the drawing smoothly.

  • 3D Orbit: Rotate the model in three dimensions.

  • Named Views: Saving and recalling specific viewpoints.

Accurate Drawing Techniques (10 minutes)

• Absolute vs. Relative Coordinates: Entering precise points.

• Grid & Snap, Polar, and Ortho Modes: Enforcing straight lines and angles.

• Object Snaps (OSNAP): Endpoint, midpoint, center, intersection.

Basic Geometry Creation (25 minutes)

• Lines & Polylines: Drawing single lines, connected segments, and editing grip handles.

• Circles & Arcs: Center-radius, three-point circles, and different arc commands.

• Splines: Creating smooth curves and adjusting fit points.

• Practical Tips: Using grips to edit geometry on the fly.

Blocks & Attributes (25 minutes)

• Defining Blocks: Converting sets of objects into a reusable block definition.

• Inserting & Scaling Blocks: Placing instances and adjusting scale factor.

• Attributes in Blocks:

  • Creating attribute fields within block definitions (e.g., part numbers, labels).

  • Editing attribute values after insertion.

• Best Practices: Organizing block libraries and naming conventions.
