Sketch geometry behaves differently in a sketch depending on the linetype assigned to it. In a part or assembly file, the sketch linetypes available are Normal, Construction, Centerline, and Reference.
In a drawing file, you have access to all the linetypes defined by the Drafting Standard you have selected.
Using linetypes in part and assembly sketches
| Normal | This is the default linetype. Sketch geometry using this linetype is consumed by features. |
|
Construction |
Construction geometry is used to aid in the development of sketches for parametric features. It is contained in the sketch but does not add features when the sketch is consumed. Use construction geometry to constrain normal sketch geometry. |
| Centerline | The Centerline linetype is a variation of the Construction linetype. Use it as a visual aid in determining construction axes, or to dimension to a hypothetical location on the opposite side of the centerline and equidistant from the sketch geometry selected. |
| Reference | If your sketch is projected from a part edge, it is automatically assigned a Reference linetype. Reference geometry is associative so that if the part face it is associated with is modified, the reference geometry automatically updates. |
| If you change reference geometry to another linetype it loses its associativity. |
Using linetypes in drawing sketches
When you enable sketch mode in a drawing file, all linetypes associated with the current style are available. Use these linetypes to differentiate the 2D annotations to your model.
Change linetype before creating sketch geometry
- Click Sketch tab
Format panel
Construction . Construction linetype is active when the command is selected. - Click the sketch command and create the geometry.
Note: You must be in Sketch
Change linetype after creating sketch geometry
- Click the geometry to change.
- Click Sketch tab
Format panel
Construction .
Note: You must be in Sketch mode to change linetypes.
