What are the standard 2D CAD commands for creating shapes?
Box/Rectangle - Allows the drawing of square/rectangular shapes on screen.
Circle/Ellipse - Allows the user to draw circular/elliptical shapes on the screen.
Arc - Allows the user to draw arcs on screen.
Hatch/Pattern fill - Allows the user to show sectioned surfaces on the screen.
Which 2D CAD Command(s) are used to create this shape?
The Box/Rectangle tool has been used, which allows the drawing of square/rectangular shapes on screen.
Which 2D CAD Command(s) are used to create this shape?
The circle and arc tools are used which allow the suer to draw circular shapes and arcs on screen.
Which 2D CAD Command(s) are used to create this shape?
The Hatch/Pattern fill tool is used to show the sectioned surface.
Which 2D CAD Command(s) are used to create this shape?
The ellipse tool is used to allow the user to draw an elliptical shape on the screen.
Which 2D CAD command(s) can be used to complete this view effectively?
The copy tool can be used to create a replica of a certain part of a drawing so the user does not have to remake it.
Which tool(s) are used to provide these edge types to the graphic?
The fillet tool, which puts a radius on a corner, and the chamfer tool, which puts a 45 degree angle on a corner, have been used.
Which tool(s) have been used to create these effects on the graphics?
The Trim/Break tool removes any unwanted section of a line, and the Extend tool makes a line longer (usually to meet another object).
Which 2D CAD Command(s) have been used to provide this effect on the graphic?
The Scale tool is used to change the size of an object without altering its proportions.
Which 2D CAD Command can be used to effectively reproduce this graphic?
The flip/mirror tool can be used to flip this object about the horizontal or vertical axis.
Which 2D CAD tools are used to create these two different groups of shapes?
The Radial array tool has been used to replicate the boxes in a circular arrangement, and the Box array tool has been used to replicate the boxes in a rectangular arrangement.
Which 2D CAD tool(s) are used to create this effect on the shape?
The rotate tool is used to allow the user to turn the object at any angle from a selected point.
Which 2D CAD tool(s) are used to create this effect on the shape?
The rotate tool is used to allow the user to turn the object at any angle from a selected point.
Which 2D CAD tool has been used to alter the view in this way?
The zoom tool has been used to increase the screen view so that finer detail can be seen clearly during the graphics production.
Which 2D CAD tool(s) have been used to create these effects on these shapes?
The offset tool has been used to create a line, curve, or shape a specified distance apart from one shape to another.
Which 2D CAD tool has been used to alter the view in this way?
The pan tool can be used to ‘pan’ around the screen to allow the user to see other parts of the drawing hidden from the visible screen.
Which CAD constrain type has been used to constrain these two parts in this way?
A Centre axis constrain has been used.
This lines up the round surfaces, and it is very useful when inserting a round extrusion into a round hole.
Which CAD constrain type has been used to constrain these two parts in this way?
The Mate constrain type has been used.
This makes faces touch each other, this is good when you want two flat surfaces to touch each other.
Which CAD constrain type has been used to constrain these two parts in this way?
The align constrain type has been used.
This is useful when you want two objects on the same plane as the other, so they align.
Which CAD constrain type has been used to constrain these two parts in this way?
The offset constraint has been used.
This is useful when you want two object to be offsetted at a set distance away from each other.
Which CAD Command has been used to add this third dimension to this CAD drawing?
Bonus: State another feature of this tool that can be used to remove volume from an object.
The extrude (join) tool has been used to add the third dimension to the sketch by a set distance.
Bonus: The extrude (cut) tool, in turn, would remove the distance set from another part of any 3D graphic which comes in contact with it.
Which CAD Command has been used to add this third dimension to this CAD drawing?
Bonus: State another feature of this tool that can be used to remove volume from an object.
The revolve (join) tool has been used to select a 2D sketch (profile) and revolve it to the set rotation (extents) given, e.g. 360 degrees, around the selected axis.
The revolve (cut) tool can be used to remove the revolved volume wherever it comes in contact with another 3D CAD model.
Which CAD command can be used to effectively create this edit to a standard cube?
The shell tool has been used to allow you to hollow out any shape to a set wall thickness.
