OVERVIEW

Before we talk about the settings available for dimensions, we need to understand how we set the parameters of a particular dimension.

You can either set an individual dimension's parameters directly, known as  "Individual Mode", or you can assign a dimension to use a preset style, known as a "Global Mode".  

If a dimension is set to a global mode, its parameters will be the same as any other dimension that uses the same global mode style. If the global mode style is edited, all the dimensions using that global style will also reflect the changes.

You may only want to change the parameters of an individual dimension without effecting any other dimensions. To do this you can either:

Edit the parameters by telling Caddie this will now be an individual dimension and all the parameters will be set explicitly for that dimension.

Or

Create a new style with the required parameters and assign that style to only the required dimension.

Getting the parameters from a particular measurement using the Get dimension parameters command will get that dimensions mode. So if the selected dimension was set to use global mode then once the Get command was executed all following dimension commands will use the selected global mode. Similarly if the dimension that we were getting the parameters from was set to individual mode all further dimensions would be set to individual.

 

THE DIALOGUE
 

The dialogue box is divided into a number of TABS and a common bottom section.

COMMON SETTINGS

At the bottom of the dimension parameter set dialogue box is a section which is not only common to all the tabs but also sets the way in which the dimension will be drawn.

Type

This set how the way the dimension is drawn.

Unchained

When selected all dimensions placed will require a starting point and an end point.

Chained

When set, the first dimension (A) placed will require a starting point, an end point (B) and a text position (C). All subsequent dimensions (D & E etc.) will only require an endpoint. The following dimensions start point is automatically the end of the previous measurement (assuming the command hasn't been terminated and restarted). The text position is in line with the first text position.

 

Datum

The first dimension point of a datum set is indicated followed by the end point of the first dimension and the position of the first text. You are now asked for the distance of the spacing for the next dimension. The distance between the dimension lines is set either from the Basic tab or the Lines tab "Baseline Spacing" under "Dimension Lines"

MODE

Individual

If selected, any changes made will not effect any global style. The changes will only by applied to the indicated dimension when using the DimEdit command or to any newly drawn dimensions. Whenever a dimension with a global style is edited with DimEdit command and the individual flag set, it no longer uses the global style it original had.

Global

When selected all of the parameters set will update the currently selected global style. If you want to use another style, first set the global style you want to use from the drop-down and select "Set Current". This will load the settings of the selected style and it will be this global style that is used until changed.

To change a dimension that has been set to use an individual style to a global style re-open the DimSet window and select the style you want from the global style drop-down and select global style. After closing the dialogue use DimEdit and select the dimension you want to change.

 

GLOBAL STYLES

Set Current

Sets the global style shown in the drop-down to the current selected global style.

Manage

This dialogue allows you to create new styles or rename and delete the styles you already have.

New

Create a new style. This can be based on any existing style from the "Based-On" selecting drop-down.

Specify the name for the new style.

Rename

Renames the selected style.

Delete

Deletes an existing style.

Cancel

Closes the dialogue box without saving the changes.

Auto Layering

Choose the layer that you want to use for the dimension. You will need to create the layer if it doesn't exist using the LaySet command.

With auto layering enabled, all dimensions will be forced to the selected layer, regardless of the active layer.

Styles (User Saved Settings)

Load

These are not the same as global styles that have already been discussed. Whereas global styles are part of the drawing and the dimension if used, user styles are system based and are just a collection of settings that can be loaded and used either individually or to modify an existing global style or to create a new one.

To use them select the one you want from the style drop-down and the select LOAD.

Save

To save a user style, once your parameters are as required, type the name in the style box and select SAVE. If the style already exist you will be asked if you wish to over write it. Otherwise and new one will be created.

 

TABS

It is important to note that any settings changed on any TAB page with effect either an individual dimension or a Global style dependant on the mode selected.

BASIC TAB Overview

If you are starting out with Caddie you may find that the only settings that need to be changed can be found on the BASIC tab. For advanced dimension settings the other tabs can be used.

As mentioned this tab only allows changes to a small number of the of the large number of dimension parameters that can be set. These will satisfy most users by most users.

Initially when Caddie is loaded the settings, as shown above for this dialogue, are pre-loaded. If at later date you want to pre-load different settings, you can do this by editing you template file (*.CTP) and changing these parameters to what you want. Then as long as you tell Caddie to use this template the dimension parameters you created will be re-loaded as your starting settings.

At the top of the BASIC tab page is a tick box to set the basic defaults. With it is un-ticked you will notice that all the fields are grayed out. The only way to change any of these settings is to go to the relevant tab and change the setting on that tab. The fields of the basic page will be still grayed out, but will now show the new values.

If any setting has been changed on an advanced tab page and that parameter is not shown on the basic page these changed parameters will still stay set when you go back to the BASIC tab page. However if you want to set all the settings back to defaults tick the "use basic settings" tick box. All the fields on the BASIC tab are now directly accessible. It is important to also note that as soon as this tick box is ticked then all settings NOT shown on this page will be re-set to the Caddie defaults.

Overall Target Scale

Where the target scale is indicated. This is used by all other dimensions settings. Its only purpose is to act as a calculation multiplier. So for instance if the text target size was to be 3mm and the scale of the target viewport or plot is to be 1:50 any dimension text would be drawn with a size of 150mm (3mm x 50).

Measurement Scale

Scale Factor

Sets a scale factor for linear dimension measurements. The dimension measurement value specified is multiplied the by the value entered here. So if you measure a value of 5 and the scaling value is 2 the value displayed is 10. This does not apply to angular dimensions or is it applied to rounding values or to plus or minus tolerance values.

Apply to layout dimensions only

Applies the linear scale value only to dimensions created in sheets. This sets the length scale factor to reflect the zoom scale factor for objects in a model space viewport.

Zero Suppression (Linear)

 

Angular Dimensions

Settings specifically for angular dimensions.

Unit Format

Sets the format of angular measurements.

Precision

Sets the number of decimal places the an angular measurement will use.

If ticked the alternative units will be used.

Unit Format

Sets the format of angular measurements.

Precision

Sets the number of decimal places in the dimension text.

Multiplier For Alternative Units

Specifies a multiplier to use as the conversion factor between primary and alternate units. To determine the value of alternate units, all linear distances (measured by dimensions and coordinates) are multiplied by the current linear scale value.

The length scaling value changes the generated measurement value. The value has no effect on angular dimensions,rounding values  or the plus or minus tolerance values.

Round Distance To

Sets rounding rules for alternate units for all dimension types (excluding angular measurements).

If you enter a value of 0.25, all alternate measurements are rounded to the nearest 0.25 unit. Similarly, if you enter a value of 1.0, all dimension measurements to the nearest integer.

The number of digits displayed after the decimal point depends on the Precision setting.
