What does over dimensioning a sketch mean?
What does it mean when a sketch is over dimensioned? When a sketch is over dimensioned, it just simply has repeated dimensions on the sketch.
What are the two types of dimensioning?
The basic types of dimensioning are linear, radial, angular, ordinate, and arc length. Use the DIM command to create dimensions automatically according to the object type that you want to dimension.
Why should over dimensioning be avoided?
Over-dimensioning leads to confusion by diverting attention to noncritical features. In this image, the reader could never identify the dimensions most critical for the part to function.
What is dimensioning rule?
Dimensioning Rules. 1. Each dimension should be given clearly so it can be interpreted in only one way. 2. Dimensions should not be duplicated or the same information given in two different ways (dual dimensioning excluded).
What is the difference between size dimensions and location dimensions?
Size dimensions describe the size of each geometric feature. Location dimensions tell the viewer where edges occur inside an object view.
What is linear dimension?
A linear dimension is a group design object. It places dimensioning information on the current PCB layer, with respect to a linear distance. The dimension value is the distance between the start and end markers (reference points selected by the user) measured in the default units.
What does CAD and CADD stand for?
Computer-aided design
Computer-aided design/Full name
Can extension lines cross each other?
Dimension lines and extension lines should not cross, if avoidable. However, extension lines may cross each other. 23. When extension lines cross other extension lines or visible object lines, no break in either line should be made.
How should dimensions be written in a drawing?
There are two basic methods of placing dimensions on a sketch. They may be placed so they read from the bottom of the sketch (unidirectional dimensions) or from the bottom and right side (aligned dimensions). The unidirectional system is usually best, because it is more easily read by workmen.
What’s a linear dimension?
linear dimension. A measurement of the horizontal or vertical dimension of a feature. Linear dimensions may not represent the true distance between beginning and ending dimension points because they do not take angle into account as aligned dimensions do.
