Scene Settings

MeasureIt_ARCH Styles & Settings can be found in the Scene Tab of the Properties Editor.

MeasureIt_ARCH Styles

Styles have a nearly identical user interface to their corresponding items. Style-able properties can be found in the item's settings.

Note that some settings, like an Annotations Offset, or a Dimensions Distance, are still set per item, even when using a style.

MeasureIt_ARCH Unit Settings

MeasureIt_ARCH Unit Settings can be found in Blender's Scene Settings under the Units panel. MeasureIt_ARCH makes use of Blender's Scene Unit System.

Metric Precision

• Defines the number of decimal places included in your dimensions when using the Metric Unit System.

Imperial Precision

• Fractional Precision to be used when using the Imperial Unit System.

MeasureIt_ARCH Settings

Show Dimension Text

• Show or hide the text on Dimension and Annotation elements.

Debug Text

• Writes Dimension Text to an image for Debug purposes.

Evaluate Depsgraph

• Evaluate Blender's Dependency Graph before drawing MeasureIt_ARCH elements.
  • WARNING: By default, MeasureIt_ARCH does not evaluate the Dependency Graph as some generative modifiers can give unpredictable results. Enabling this setting will make MeasureIt_ARCH attempt to evaluate these modifiers during its calculations.

Instance Dimensions

• Will Enable Dimension Instancing.
  • WARNING: Text on instanced Dimensions will not account for changes in the instances local scale or rotation.

Object Settings

• Dimension, Annotation, and Line Group settings can be found in Object Tab of the Properties Editor.
  • These panels will only appear if the active object has a dimension, annotation or line group associated with it.
  • To add dimensions, annotations or line groups use the main tool panel.

  • If no Camera is selected the Dimension will be visible in all Cameras.
  • If a Camera is selected the Dimension will only be visible when that Camera is the Active Camera.
• Line Weight: The Dimension's Line Weight.
• Distance: The Distance of the Dimension Text from the Objects or Vertices it's attached to.
• Radius (Arc and Angle Dimensions Only): The Distance of the Dimension Text from the center of the Arc or Angle.
• Offset: The offset distance from the ends of the Dimension line to the Vertex or Object it's attached to.
• Rotation: Rotates the Dimension around the axis of its measurement.
• Font Size: The Dimension font size.
• Resolution: The Dimension font resolution.
• Alignment: The Dimension text alignment relative to the dimension line (Left, Center, Right).

• Arrow Size: The size of the Dimension's terminations.
• Arrow Angle: The angle of Dimension's triangle and arrow terminations.
• Draw In Front: Makes this element Ignore Visibility tests.
• Evaluate Depsgraph: Evaluate Blender's Dependency Graph before drawing this MeasureIt_ARCH element.

Line Groups

• Color: Sets Line Group Color.
• Draw Hidden Lines (Cube with Dashed Lines Icon): This Line Group will draw hidden lines as dashed lines.
• Link Style (Link or Broken Link Icon): Toggles if this Line Group uses a Style.
• Visibility (Eye Icon): Toggles visibility of the Line Group.
• Delete (x Icon): Deletes the Line Group.

• Line Weight Group: Use a vertex group's values to modify the line weight.
• Influence: Adjust the influence of the Line Weight Group.
• Z Offset: Tweaks the Line Group's Distance from the screen in Clip Space. Higher values move the Lines closer to the screen.
  • This is useful for adjusting Line Groups that don't appear to be drawing correctly (Jagged Edges, etc.).
  • Making this value negative allows for the drawing of silhouettes. Higher values will move lines further backwards
• Extension: Adds a slight over-extension to each line segment in this Line Group.
• Hidden Line Color (Only Available if Draw Hidden Lines is Enabled): Sets the color of hidden lines.
• Hidden Line Weight (Only Available if Draw Hidden Lines is Enabled): Sets the line weight of hidden lines.
• Dash Scale (Only Available if Draw Hidden Lines or Draw Dashed is Enabled): Changes the dash size of dashed lines. Larger values make smaller dashes.
• Dash Spacing (Only Available if Draw Hidden Lines or Draw Dashed is Enabled): Changes the dash spacing for dashed lines. 0.5 gives even spacing.
• Draw Dashed: Draws all lines in this Line Group as dashed lines, regardless of visibility.
• Screen Space Dashes: Calculates Dash Spacing in Screen Space. Useful to achieve more even dashes in still renders when some lines are nearly parallel to the view. Can cause dashes to appear to 'slide' along edges when used in animations.
• Draw In Front: Makes this element Ignore Visibility tests.
• Evaluate Depsgraph: Evaluate Blender's Dependency Graph before drawing this MeasureIt_ARCH element.

Annotations

• Color: Sets Annotation Color.

Rendering

MeasureIt_ARCH Render Settings can be found in the Render Panel of the Properties Editor. Currently this renders all MeasureIt_ARCH items to an image file which can be layered over Blender's render in the compositor.

MeasureIt_ARCH Image

• Renders a Still Image.
  • WARNING: If 'Save Render to Output' is not enabled the rendered image will only be stored in an image data-block within Blender.

MeasureIt_ARCH Animation

• Renders the full frame range of the current scene.
  • Animation Renders can be Cancelled with the Esc key, or by Right Clicking in the 3D View.
  • A 3D Viewport window must be open for MeasureIt_ARCH to render animations.
  • Animation frames will be saved to the Output path defined in the Render Panel.

Save Render to Output

• Saves Still Image renders to the Output path defined in the Render Panel after rendering.
