What is co ordinate dimensioning?
Coordinate Dimension command. Places a dimension that measures the distance from a common origin to one or more keypoints or elements. You should use coordinate dimensions when you want to add dimensions in relation to a common origin or zero point.
Where is the datum origin for the dimensions?
Ordinate dimensions measure the perpendicular distances from an origin point called the datum, such as a hole in a part. The datum is established by the current location of the UCS origin. Move the UCS origin to the datum.12 août 2020

How do you do ordinate dimensions in Creo?
1. Click Annotate > Ordinate Dimension or Annotate > Annotations > Ordinate Reference Dimension.
2. Select one of the reference options on the Select Reference menu and select a baseline reference on the drawing.
3. Hold down the CTRL key and select another entity to create ordinate dimensions for the selected entities.
What is baseline dimensioning?
A baseline dimension is a group design object. It allows for the dimensioning of a linear distance of a collection of references, relative to a single base reference. … The dimension value in each case is therefore the distance between each reference point and the ‘base’, measured in the default units.30 août 2017
What is an aligned dimension?
aligned dimension. A drafting symbol that runs parallel to the baseline and indicates the true distance between beginning and ending dimension points.
What does Gd and t mean?
Geometric Dimensioning and Tolerancing
Why do we use GD&T?
Geometric Dimensioning and Tolerancing (GD&T) is a design approach and manufacturing mechanism that helps engineers and designers communicate how to bring a part design to life. … The drawing is the controlling document that ensures the vendor is creating precisely what the customer’s design requires.12 sept. 2016
What is RFS GD&T?
Definition: Regardless of Feature Size (RFS) is the default condition of all geometric tolerances by rule #2 of GD&T and requires no callout. Regardless of feature size simply means that whatever GD&T callout you make, is controlled independently of the size dimension of the part.
What is the datum origin?
Datum measurements are the horizontal and vertical distances measured from a datum origin. The Datum Origin option allows the user to select one point on the part to use as the reference for all other datum dimensions. There can be only one datum origin per part. …
What is arc length dimension?
The Arc Length Dimension tool measures and dimensions the length of an arc anywhere along its circumference. The dimension can be shown with its witness lines perpendicular to a chord on the arc, or perpendicular to a line tangent to the arc.
What is datum dimensioning?
A datum dimension is a group design object. It allows for the dimensioning of a linear distance of a collection of objects, relative to a single reference object. … The dimension value in each case is therefore the distance between each reference object and the ‘base’, measured in the default units.30 août 2017
