Create a Rowboat Mechanism Using Siemens Solid Edge

Start with a rowboat built around slider crank mechanism, a four-bar linkage for linear and rotational motion, and organize six 3D parts: frame base, connecting rod, slide, crank, leg, thigh.

Open a new metric assembly in Siemens Solid Edge, access the parts library to start with the grounded frame base as the first non-moving part, then save the mechanism.

Select the crank axis from the parts library, place and mate it to the frame base, and align its faces. Use top view to ensure gaps avoid 3D print lockups.

Learn to model a slider in Siemens Solid Edge by applying tangent constraints between cylinders and faces, aligning from front/top views, and ensuring proper clearance for 3D printing.

Drag and place the connecting rod, set the center plane constraint to double, and center the faces between them. Verify a centered gap to ensure smooth 3-D printing without jamming.

Conduct a motion check by using the drag component on the crank to run the mechanism and verify it operates as expected, noting any serious problem and where it occurs.

Edit the frame, extend the slot, and drag faces to resolve interference in the mechanism, using show/hide controls and precise dimensions to achieve a proper crank fit.

Add the thigh from the parts library and rotate it on the peg. Apply a center plane constraint between the selected faces and verify the alignment from a top view.

Attach the leg from the parts library, align the hole to the pin, and apply a center plane constraint to center the faces, ensuring proper alignment for 3-D printing.

Explore how to add a rotational motor in Siemens Solid Edge, simulate movement, and adjust leg alignment to achieve the desired motion.

In this lesson, the instructor adds the thigh and aligns it to the center planes in the rowboat mechanism, using the top view, escape key, and right-click to verify orientation.

Add the second leg to a rowboat mechanism in Solid Edge from the parks library, align with a center plane, center between two features, and adjust via drag and rotate.

Drag in the router to add the body, adjust its position in the front view, and extend the slide to fit, illustrating real-world design tradeoffs.

Extend the slider by box pick and dragging it about 2 millimeters, then sketch and center two equal circles on front reference plane using center-point constraints to align the geometry.

Attach the body to the mechanism by aligning an axial line from the center to the axis, then align with the center plane. Verify the positioning in the top view.

Attach the arms to the mechanism by aligning the bar with the hole, center the placement, and verify from the top and front views before moving on.

Simulate the mechanism's motion to verify all components move correctly, identify any problems, and make the necessary adjustments to ensure smooth operation.

Shorten the leg to reduce jamming and add room, considering a longer frame base or shorter thigh and leg; change the 16.5 dimension to 14.5 and test the motor.

Identify and fix interference issues in the rowboat mechanism design using Siemens Solid Edge, inspecting leg and thigh clearance during 3D printing and iterative adjustments to the drag component.

Fix the interference and assess the form, fit, and function of the connecting rod. Adjust dimensions, round edges, and restore thickness to 4.2 while lightening parts.

Improve the crank design by sketching a 2.5 diameter feature, applying a circular eight-instance pattern around center, and adding a spherical cutout with a reference plane while rounding the edges.

Replace and re-constrain the leg components in a rowboat mechanism design using Siemens Solid Edge, implementing the new leg design and aligning them to the pin holes.

Design the boat inside the rowboat mechanism assembly by creating a new part, sketching on the top plane, extruding, and refining with construction geometry and thin walls.

Position and center the oarlocks and oars in the rowboat model, aligning the shaft and cylinder. Use the connect tool to snap parts into the pocket and verify fit.

Explore how to assemble a rowboat mechanism without screws by using a front clip, a half-cylinder back mount, and a plastic lift to secure the 3D-printed components inside the boat.
