What advantages do Autodesk Inventor sketches have over freehand sketches?
The advantages that CAD sketches have over freehand sketches are that you edit it the sketch easily and you can see how the parts will come to life. The disadvantages that CAD sketches have when compared to freehand sketches are that freehand sketches are tangible and you are drawing multi-views.
What type of numeric constraints may be applied to sketches?
Some types of numeric constraints that can be applied to sketches are dimensions, diameters, and extrusions.
What advantages do CAD drawings have over paper sketches?
Some advantages that CAD drawings have over paper sketches include, being more neat, more precise, quicker to make, more available space to work with, unlimited resources to work with, easy availability to apply constraints to a sketch, easier sharing of work (ex: email, picasa, etc.).
What kind of constraint is not numerical CAD?
A Geometric constraint is a Constant, non-numerical relationship between the parts of a geometric figure. 2. What are the different types of geometric constraints that are applied to sketches, and what are their functions? Perpendicular is a constraint that causes lines or axes of curves to meet at right angles.
What is a dimensional constraint?
Dimensional constraints control the size and proportions of a design. They can constrain the following: Distances between objects, or between points on objects. Angles between objects, or between points on objects.
Can a drawing be a model?
Both the drawing and modeling approaches to design result in a familiar engineering drawing. In the 2D approach, the drawing captures the physical information needed to create the part. In the solid modeling approach, the drawing is one of several uses for the created model.
What is the difference between dimensional constraints and geometric 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.
What are constraints in drawing?
Constraints are rules that are applied to 2D geometry. By applying constraints, you can control the location, size, distance, angle, and other parameters of objects in a drawing.
How can we confirm a sketch is fully constrained?
How can we confirm that a sketch is fully constrained? Have a Geo and dimensional constraint. You just studied 10 terms!
What disadvantages are there to using parametric equations for numeric values?
What disadvantages are there to using parametric equations for numeric values? It is more time consuming to set up. 4. Describe a situation in which using parametric equations to dimension an object would be helpful.
How can we confirm that a sketch is fully defined solidworks?
FULLY DEFINED SKETCH On more complex sketches with 100+ lines, looking on the bottom right corner the SolidWorks interface will help tell the user if the sketch is fully defined.
Does Solidworks allow us to build partially defined solid models?
We can use SOLIDWORKS to build partially defined solid models. However, SOLIDWORKS will not let us over-define a sketch; additional dimensions can still be added to the sketch, but they are used as references only.
Which translator is suitable for small CAD CAM system?
Neutral translators are used to convert a proprietary CAD or CAM data format into a generally agreed upon industry standard. They are documented and available for anyone to use. The primary neutral translators today are IGES for surface data and X_T or SAT, which were developed for solid modeling data.
How do we distinguish between derived dimension and regular dimension?
How do we distinguish between derived dimensions and regular dimensions on the screen? Derived has parenthesis, regular doesn’t. Describe the procedure to Display/Edit user defined equations. Related dimensions change according to each other.
How can you tell the difference between a parametric dimension and a regular dimension in a sketch?
Normal, or general, dimensions are parametric dimensions that determine the size of sketch geometry – they “drive” the geometry. When you change the value of a normal dimension, the geometry resizes accordingly. Driven dimensions, conversely, are nonparametric dimensions that show the current value of geometry.
Which 3D tool requires two sketches one for the profile and one for the path?
Sweep tool
How do I make dimensions the same in Solidworks?
Double click the dimension, then in the Modify dialog box, type = (equal sign). You must enter the equal sign to assign a global variable to the dimension. If you do not enter the equal sign, you can create a new global variable, but it will not be assigned to the dimension.
What is the main difference between a rough sketch and a profile?
What is the main difference between a rough sketch and a profile? A rough sketch is imprecise while a profile is the exact sketch used to create a solid feature.
What is the parametric modeling procedure?
Parametric modeling is a modeling process with the ability to change the shape of model geometry as soon as the dimension value is modified. Parametric modeling is implemented through the design computer programming code such as a script to define the dimension and the shape of the model.
