Solidworks Application - Drawing a Walker - with English subtitles

Modeling the Walker Frame (Initial Sketch & Sweep)
📌 The initial sketch was created on the right plane using a centerline originating from the origin.
📏 Dimensions were set using the Smart Dimension tool, with the side length set to 47 cm and the total height to 90 cm (using $47/2$ for equal side distances).
⚙️ A Swept Boss/Base feature was used with a circular profile having a radius of 4 to form the main frame components based on the drawn path.

Creating and Patterning Holes
🔺 A sketch on the front plane was used to define the hole locations in wireframe view.
🔢 The Linear Sketch Pattern tool was employed to copy a circle (diameter 2) along the Y-axis 8 times, with a spacing distance calculated based on the total length (distance of 4 between shapes).
✂️ An Extruded Cut feature used the Midplane option to cut through both sides of the solid shape.

Shelling and Foot Covers
🔄 The Shell command was applied to the entire model with a thickness of 0.50 to make the interior empty after the initial solid extrusion.
🔩 The foot covers were created using an Extrude command with the Thin Feature selected (thickness 1, direction inward) after sketching a diameter 5 circle on the respective faces.
📐 The Edit Feature command was used to apply a Taper degree of 3 to the foot cover extrusion features.

Top Element Creation and Manipulation
⬆️ A sketch on the front plane (diameter 5 circle) was extruded using the Midplane direction for a total length of 10, resulting in a thin feature (thickness 0.5 inward).
🔗 The Move/Copy feature was used to duplicate this body 1 copy in the X direction by 52 units.
❌ The Merge Result option was deselected during the final sweep feature creation to ensure the new connecting part remained a separate body initially.

Final Assembly and Combination
📏 A 3D Sketch was utilized to draw the connecting support lines between the two main vertical elements, using the TAB key to switch drawing axes (Z-axis focus).
🔩 A Swept Boss/Base feature with a Thin Feature (thickness 0.5 inward, circular profile radius 4) created the final connecting piece.
🧩 The Combine command was used with the Add operation on all distinct solid bodies to merge them into a single resulting body.

Key Points & Insights
➡️ When setting dimensions for symmetry, SolidWorks can perform simple calculations like $47/2$ directly in the input box.
➡️ Use the Shell command *before* final features if the intent is to hollow out the entire object, or use Thin Feature in Extrude for localized hollow features.
➡️ To ensure parts remain separate bodies for later positioning or assembly, deselect the "Merge Result" option during feature creation (like in Extrude or Sweep).
➡️ Utilize the TAB key within 3D Sketch mode to precisely control the axis (X, Y, or Z) along which the next line segment is drawn.
