CAD sketches can show exact dimensions and are more proportional than freehand sketches. What advantages do CAD sketches have over freehand sketches?
The Fillet sketch tool is used on 2D sketches and the Fillet placed feature is used on 3D models
.
What kind of numeric constraints may be applied to sketches?
Some types of numeric constraints that can be applied to sketches are
dimensions, diameters, and extrusions
.
Why is it important to fully constrain a sketch?
The importance of fully constraining your sketches in Inventor
cannot be over stated
. When a part or sketch is not functioning correctly, it can almost always be traced back to an unconstrained sketch.
What are the different types of geometric constraints that are applied to sketches and what are their functions?
Some examples of geometric constraints include
parallelism, perpendicularity, concentricity and symmetry
. Parallelism occurs when two or more lines or axes of curves are equidistant from each other. Perpendicularity is a constraint in which lines or axes of curves intersect at right angles.
What advantages do CAD sketches have over freehand sketches?
CAD sketches can show exact dimensions and are more proportional than freehand sketches. What advantages do CAD sketches have over freehand sketches?
The Fillet sketch tool is used on 2D sketches and the Fillet placed feature is used on 3D models

What CAD feature would be used to most efficiently model a baseball bat Extrude Loft Revolve Sweep )?
a. The CAD feature that would be used to most efficiently model a baseball bat would be revolve because
a baseball bat is rounded and its sides are not parallel
. 2. How does a 3D CAD solid model program display the progression of work involved in creating a model?
What are the advantages of freehand sketches for beginners?
Freehand drawing
enables visualization of an idea in the form of a sketch
. It is also a universal language designers use to communicate with other participants of a project. That is why freehand drawing ought to be an inherent element of a design process, especially in the first conceptual phase.
What kind of constraint is not numeric?
A Geometric constraint
is a Constant, non-numerical relationship between the parts of a geometric figure.
What are the type of geometric constraints?
A geometric constraint is
a non-numerical relationship between the parts of a geometric figure
. Geometric constraints: Associate geometric entities together two by two (coincident, concentric, collinear, parallel, perpendicular, tangent, smooth, symmetric, equal).
What does fully constrained mean?
When an object is fully constrained,
all relevant geometric and dimensional constraints are applied to the geometry
. You should always fully constrain geometry in a dynamic block definition that contains constraints to prevent unpredictable behavior during block insertion.
Why are my lines Blue in Fusion 360?
Blue lines mean that
the sketch object is not fully constrained and dimensioned also sometimes
referred to as not fully defined. A sketch item will turn from blue to black as soon as it is fully defined.
How can you make sure a sketch is fully constrained?
When a sketch is fully constrained,
the sketched features will all be the same color and will not move if they are clicked and dragged
.
What is a tertiary constraint?
constraints. … The secondary constraints arise directly from the condition that the primary constraints are preserved by time, the tertiary constraints arise
from the condition that the secondary ones are also preserved by time
, and so on.
What is the difference between geometric and dimensional constraints?
There are two types of constraints: geometric and dimensional. Geometric constraints are used to control the relationships of objects in respect to each other. Dimensional constraints are used to
control the distance, angle, radius
, and length values of objects.
Which sketch constraint causes two or more line segments or ellipse axes to lie on the same line?
The Parallel constraint
causes selected lines or ellipse axes to lie parallel to one another. In a 3D sketch, Parallel is available for sketch geometry, axes, planes, spline handles or to selected model geometry.
When using a 3d CAD program How do you make a correction without using the Undo function?
2. If a mistake is made, how does the user make a correction without using the undo function? Answer:
To delete a mistake on inventor, the user would use the delete key
.
