CAD Modelling for Blender
Overview And Key Functions
Construction Lines is a tool for accurate CAD style modelling. Build snappable guide points and edges, draw lines and primitive shapes in place, automatically create faces in closed geometry and precisely move object geometry around a scene.
Guide edges and points allow for a construction workflow where guides are set and models are then constructed within these guides. The guides won't interfere with model geometry and can be toggled off and on when required. Guides edges will disappear when working outside of Construction Lines and neither Guide Edges nor Guide Points will be rendered.
Construction Lines allows for rectangles, circles, and arcs to be drawn in place from precise snap points on existing geometry or guides. These can be drawn from anywhere on a 3D model without the need for Blender's 3D cursor to define an Add location.
Construction Lines works seamlessly between Object and Edit modes in Blender.
If you come from software packages such as SketchUp this is a perfect way to get started with Blender
NOTE: Construction Lines is currently in Beta and is regularly updated with fixes and improvements.

Guide Edges & Points
Drawing Shapes In Place
Precise Object Moving
- Create snappable guide edges and points
- Precisely measure distances
- Build rectangles, circles and arcs anywhere in your scene
- Draw lines simply by clicking and dragging in the 3D viewport
- Lines will automatically fill in faces where geometry is closed
- Use lines or shapes to cut into or divide existing geometry
- Build lines, shapes and guides to exact size with numeric input (including mathematical operators * / + -)
- Limit drawing and movement to the X, Y or Z axis
- Accurate object movement with snap points or numeric input
- Create faces from a list of selected snap points (vertex, edge, edge center, face)
Features In Development
- Automatic face splitting when adding a new shape away from an edge in existing geometry (Blender won't split a face if there is not a connecting edge)
- Angle measurement between objects/geometry points
- Rotation of guidelines/objects to a snapped point - means you can rotate and snap to a distant unconnected vertex/edge/face
- Dragging guides/objects locked perpendicular to an existing guide edge or geometry edge
- Big performance improvements when cutting into existing geometry
- Fixed stability issues when using shapes to cut into existing geometry
Please note that upgrading from version 0.9.0 requires removal of version 0.9.0 from Blender before installing any new version.
- Dimension input now allows for Imperial values (when Blender's Unit System is set to Imperial) - Values can be written in multiple ways eg. 12'1" 3/8, 12'1, 12' 3/8, 12. Decimals can be used for the first value. Will work with either Feet or Inches set as the Length Unit
- Hold Ctrl and using the mouse wheel will allow for changes in circle/arc segments and will also automatically add guide point divisions to the current guide edge - Whilst dragging a guide edge use Ctrl+Mouse Wheel to increase/decrease the number of guide divisions
- A guide point is now added to the start of a guide edge
- Bug fix to arc and circle when using with existing geometry face - was not cutting correctly - NB. This is a patch fix, the face finding and face intersection system will be re-written for the next Construction Lines Version
- Bug fix to measurement scale - was not previously taking into account the user-entered Unit Scale only unit type scale
