What is ordinate dimension in Autocad?

Ordinate dimensions are used to locate the X or Y coordinate value of a point. Click point 1 to identify the point location, click point 2 to locate the dimension line. Ordinate dimensions are especially useful for elevations or OS grids which use specific coordinates.

When should you use ordinate dimensions?

Use ordinate dimensioning when possible. This greatly simplifies the machining process because the dimensions on your drawing directly match the digital readouts on the milling machines. Ordinate dimensioning is used when the X and the Y coordinates, from one location, are the only dimensions necessary.

Can ordinate dimensions be basic?

We have a pattern of holes which are located using ordinate dimensions. Their tolerance zones are specified using a position tolerance frame, so the dimensions themselves are basic.

How do I add to ordinate dimensions?

To add more dimensions along the same ordinate: Right-click an ordinate dimension, and select Add To Ordinate. Click the edges, or vertices, or arcs you want to dimension using the same ordinate. As you click each item, the dimension is placed in the view, aligned to the zero ordinate.

What is co ordinate dimensioning?

Coordinate dimensioning creates a series of “chained” dimensions having a common origin and single dimension line. Baseline dimensioning creates dimensions from a common origin using long or short baselines, and where the dimension labels are on unique but parallel dimension lines.

How do you use ordinate dimension in Inventor?

  2. In the graphics window, select the view to dimension.
  3. Place the origin indicator.
  4. Select the geometry to dimension in the graphics window.
  5. Right-click and select Continue.

How do I create an ordinate dimension in Solidworks?

To create ordinate dimensions:

  1. Click Ordinate Dimension on the Dimensions/Relations toolbar, or click Tools, Dimensions, Ordinate.
  2. Click the first item (edge, vertex, and so on) from which all others will be measured to be the base (the 0.0 dimension), and click again to place the dimension outside the model.

How do you use 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 coordinate tolerancing?

Coordinate tolerancing is a dimensioning system where a part feature is located (or defined) by means of rectangular dimensions with given tolerances.

Why is GD important?

GD, a vital part of complex machining, offers a number of major advantages: Saving Money — GD enhances design accuracy by allowing for appropriate tolerances that maximize production. For many projects, the process provides extra or bonus tolerances, further increasing cost effectiveness.

What is unidirectional dimensioning?

The unidirectional method means all dimensions are read in the same direction. The aligned method means the dimensions are read in alignment with the dimension lines or side of the part, some read horizontally and others read vertically.

How do I show hidden ordinate dimensions in Solidworks?
