Tesla CAD Modelling Prelims

The command "ucs" or "UCS" in Autocad is used to rotate the grid at a 45-degree angle. This command allows the user to define a new coordinate system, known as the User Coordinate System, which can be rotated and aligned to any desired angle. By using this command, the grid can be adjusted to match the desired orientation for drawing or modeling purposes.

Pro/ENGINEER has been rebranded as Creo Elements/Pro, indicating that it is the first step towards the new software called Creo.

The correct answer is "Parametric Technology Corporation" or "parametric technology corporation" because PTC is an abbreviation for this company.

The typical parts list should include all of the above. A parts list typically includes the part number, which helps in identifying and ordering the correct part. It also includes the manufacturing material, which is important for understanding the characteristics and properties of the part. Additionally, the number of parts needed is mentioned in the list to ensure that the correct quantity is procured. Therefore, all these elements are essential and should be included in a typical parts list.

A polyline is a tool that allows for the creation of lines with varying widths. By manipulating the control points of the polyline, the width can be adjusted to create a line with a tapering effect. This makes the polyline tool the ideal choice for creating a line with a tapering width. The other options, such as circle, ellipse, and line, do not have the capability to create a tapering width.

The View toolbar in a 3-D solid modeling software allows users to manipulate the viewpoint of the solid. "Front" refers to the front view of the solid, "left side" refers to the left side view, and "SE isometric" refers to the southeast isometric view. Therefore, selecting "all of the above" means that the View toolbar can position the view of the 3-D solid towards any of these directions.

To cycle through the available snap points, you press the Tab key. The Tab key is commonly used to move the focus between different elements or sections within a program or interface. In this context, pressing Tab allows the user to navigate and select different snap points, which are predetermined positions or alignments that objects can snap to for precise placement or alignment purposes.

The incorrect option about the type of AutoCAD drawing units is "Millimeter". AutoCAD does support millimeters as a unit of measurement for drawings. The other options, Architectural, Engineering, and Decimal, are all valid unit types in AutoCAD.

The correct answer is "Displacement diagram." A displacement diagram is a curve that represents the displacement of the follower as ordinates on a base line that represents one revolution of the cam. It shows the movement of the follower in relation to the rotation of the cam, allowing for analysis and understanding of the cam mechanism's behavior.

A chamfer is an angled surface that is used on cylinders to make them easier to handle. It is typically created by cutting or grinding away the sharp edge or corner of the cylinder, resulting in a beveled or sloping surface. This chamfered surface helps to prevent any sharp edges or corners from causing injury or damage, and also makes it easier to grip and handle the cylinder.

When setting up a mechanical drawing in AutoCAD, it is recommended to set the units to decimal. This is because decimal units are commonly used in mechanical engineering and provide a more precise and accurate representation of measurements. Decimal units allow for easier calculations and conversions between different units of measurement, making it the preferred choice for mechanical drawings in AutoCAD.

To ensure precise placement when inserting blocks into a drawing file, the drafter should make sure that "O Snaps" is turned on. O Snaps, or object snaps, allow the drafter to snap the cursor to specific points or objects in the drawing, such as endpoints, midpoints, intersections, etc. This feature helps in accurately aligning and positioning the blocks within the drawing.

The correct answer is 0,0 and 18,24. This is because "C" size architectural drawings typically have dimensions of 18 inches by 24 inches. By setting the drawing limits to 0,0 and 18,24, the drafter ensures that the entire drawing will fit within these dimensions.

When creating your own blocks, it is important to avoid drawing any portion of the block in the 0 layer.

When drawing a line using the relative coordinate system, the line is created starting from the ending point of the last line. This means that the coordinates of the new line are calculated relative to the ending point of the previous line. By using the relative coordinate system, the position of each line is determined based on the previous line's ending point, allowing for the creation of a continuous path.
