Horizontal Dimension

Introduction

This topic will explain the Horizontal Dimension function, will explainwhere to find the function, and explain the options found in it.Thistopic will also give a brief description of creation with quick steps, and provide linksto related topics.

Note: Though there are separate topics for each dimension topic, the Data Entry Parameters used in the functions are all the same.

The Horizontal Dimension Function

The Horizontal Dimension function is used to create a dimension along the X axis in the graphics area.This can be accomplishedby picking points or snap points in the graphics area, and alteringthe data entry information as needed.

To open Horizontal Dimension:

  • In the Dimensions group, of the Evaluate ribbon, click Horizontal.

The parameters display in the Data Entry Manager.

The Data Entry Parameters

Creation Option

Font

  • Font- Select a font type: WindowsFont or BobCADFont.
  • Font List- Click the arrow to select the font from the list.
  • Height- sets the height of the text on the created dimension.

Selected Geometry

 

(Delete) - removes the highlighted item from the Selected Geometry list.

(Delete All) - removes all entities from the Selected Geometry list.
The list will display all entities currently selected for the function.

Dimension

  • Decimals- sets the number of decimal places, or digits after the decimal point,displayed in the dimension text.These are only displayed for valuesthat aren't whole numbers, unless Extra Zeroes are selected.

  • Scale- sets the scale of the measured dimension.A value of one means noscaling or 100 percent of the actual size of the entity.A value of0.5 means that when you place a dimension on a line that is two unitslong, the dimension displays a value of one unit.

  • Extra Zeroes - determines whether trailing zeros areused.

- Trailingzeros are not used.As an example, if a value of four is used for theDecimals option, a dimension of 1.1 would appear as 1.1 in the graphicsarea.

- Trailingzeros are used.As an example, if a value of four is used for the Decimalsoption, a dimension of 1.1 would appear as 1.1000 in the graphics area.

Tolerance

None - does not show any tolerance values after the initial dimension.
Single - shows only one tolerance value.This value is listed as a positive value unless otherwise specified.
Symmetric - shows only one tolerance value.This value is listed with a positive and negative symbol in front of it to show the tolerance range.
Custom - shows two tolerance values.These values are listed as positive values unless otherwise specified.

  • Extra Zeroes - determines whether trailing zeros areused.

- Trailingzeros are not used.As an example, if a value of four is used for theDecimals option, a dimension of 1.1 would appear as 1.1 in the graphicsarea.

- Trailingzeros are used.As an example, if a value of four is used for the Decimalsoption, a dimension of 1.1 would appear as 1.1000 in the graphics area.

Text Options

The Text Options group is used to displaycustom text in the dimension.The chevron to the left will also allowyou to collapse and expand the entire group.

  • Pre- type text in this box and it is placed before the displayed dimensiontext.

  • Post- type text in this box and it is placed after the displayed dimensiontext.

  • Text Orientation - this toggle will allow you to switch the dimension text from a horizontal to a vertical orientation.

Arrows

Style

  • Left - By default the Left option will be setto the arrow style currently used in the Part Settings dialog.However,the Left option allows you to update the arrow style onthe fly without going to the Part Settings dialog to do so.

  • Right - By default the Right option will be setto the arrow style currently used in the Part Settings dialog.However,the Right option allows you to update the arrow style onthe fly without going to the Part Settings dialog to do so.

  • Auto- places the arrows on the inside of the witness lines,unless the listed value and the arrows overlap.If the listed valueand the arrows would overlap, the arrows will automatically be shiftedto the outside of the witness lines.

  • Out- places the arrows on the outside of the witness lines.

  • In- places the arrows on the inside of the witness lines

  • Width- sets the width of the arrows being used.

  • Length- sets the length of the arrows being used.

Position

When creating dimensions by selecting snappoints, Left refers to the first point, and Right refers to the secondpoint:

  • Both- two arrows are used, with one pointing to each witness line.
  • Left- one arrow points to the left witness line.
  • Right- one arrow points to the right witness line.
  • None- no arrows are used.

  • OK - finalizes the function.

  • Cancel - exits the function.

Quick Steps - Horizontal Dimension

  1. Open the function.

    The Selected Geometry list automatically has focus.

  2. Select the items to be dimensioned.

    The items are added to the Selected Geometry list.

    The dimension preview appears and its position follows the cursor.

  3. Move the cursor to position the dimension roughly into the area of intended placement, and click to temporarily set its placement.

  4. Adjust the parameters in the Data Entry Manager to achieve the desired font, text size, listed values etc.

  5. If the updated style of the dimension calls for its position to be moved, move your cursor into the graphics area above the dimension value, until the dimension highlights.

  6. Click the highlighted dimension.

    The dimension is able to be relocated.

  7. Move the dimension into its final placement.

  8. Click to set placement.

  9. Click OK to finalize.

  10. Repeat as necessary.

  11. Click Cancel to exit the function.
