MODUL 1 Axis | Praktikum Menggambar Teknik 2026

Summary

The video introduces Module 1: Axis in an engineering-drawing practicum. Presenter Sandi Aulia demonstrates basic SolidWorks operations and two ways to model a stepped axis: building it with extrusions and cuts, or drawing its side profile and revolving it.

SolidWorks basics

• CAD (computer-aided design) is used to create designs.
• CAE (computer-aided engineering) is used to analyze and test designs.
• CAM (computer-aided manufacturing) supports the manufacturing process.
• Start a new document by clicking the New icon or pressing Ctrl+N. Choose a document type:
  • Part for creating a 3D model.
  • Assembly for combining parts.
  • Drawing for creating a 2D drawing from a model.
• The practicum uses MMGS units: millimetres, grams, and seconds.
• The Front, Top, and Right planes provide the main views for beginning sketches. Select a plane and use Normal To to align it with the screen.
• The origin is the model’s coordinate centre. The video emphasizes starting sketches there and closing profiles where required.
• For navigation, scroll to zoom, hold and move the scroll wheel to rotate, and press Ctrl+7 to return to the initial view.

Method 1: Build the axis using extrusions and cuts

1. Create a new Part and set the units to MMGS.
2. Select the Right plane and choose Normal To.
3. Sketch a circle centred on the origin. Use Smart Dimension to set its diameter to 30 mm.
4. Use Extruded Boss/Base to create a blind extrusion of 80 mm.
5. Select the end face and sketch another circle with a diameter of 25 mm.
6. Use Cut-Extrude, choose Blind, and set the cut depth to 55 mm. The presenter says to enable Flip side to cut so the cut is made outside the sketched circle.
7. Repeat the sketch-and-cut process with circles of 20 mm, 16 mm, and 12 mm in diameter, using cut depths of 40 mm, 25 mm, and 10 mm, respectively. The presenter again says to enable Flip side to cut.
8. Save the completed model as Axis 1 in the folder created for the practicum.

The successive circular cuts form the stepped shape of the axis.

Method 2: Draw a stepped profile and revolve it

1. Create another Part, use MMGS, and select the Front plane. Choose Normal To.
2. Use the Line tool to draw a closed, five-step profile, starting at the origin and eventually connecting back to it. The software’s inference guides help keep the lines straight.
3. Apply Smart Dimension to the profile. The subtitles give a bottom horizontal length of 80 mm and step-related dimensions of 10 mm, 25 mm (corrected aloud from 50), 40 mm, and 55 mm.
4. Set the profile’s radial heights using half the relevant diameters. The subtitles explicitly refer to values such as 12/2, 16/2, 25/2, and 30/2. Some dimension instructions are unclear in the auto-generated captions.
5. Choose Revolved Boss/Base. Select the profile contour and set the bottom horizontal line as the axis of revolution.
6. Set the revolution angle to 360° for a complete axis. The presenter notes that using an angle such as 160° creates only a partial revolution.
7. Save the second model. The subtitles give its filename as AKIS 2.
