LWCAD 2018 video: Snap panel update

LWCAD since version 2 contains a complete snap engine which is fully integrated into all of the LWCAD tools. Snap modes are adjustable through the “Snap Panel”.

UCS: - See UCS page.

SNAP - Master snap enable-disable button.

BG LAYERS SNAP - Allows you to snap geometry in background layers.

Snap Modes

• NEAR: Snap to nearest geometry including NURBS surfaces.
• END: Snap to nearest ‘segment end’ of curve or ‘edge end’ of polygon.
• PNT: Snaps to the nearest point.
• PERP: Snap to the nearest geometry, which is perpendicular to the previous handle of current tool.
• TAN: Snap to nearest geometry, which is tangent to the previous handle of the current tool.
• CENT: Snaps to the center of the nearest geometry.
• INT: Snaps to intersections between polygons edges, curves, lines, axis and projections.
• AXIS: Snaps to X,Y,Z axis of current UCS.

Ruler Settings

• RULER SNAP: Button enables the rule snap mode.
  • rule mode works only in conjunction with snap to near or projective snap
  • it can work in absolute or relative mode
  • starting with LWcad 5 ruler snap is based on precise 'distance on curve' calculation
• Absolute: Mode allows you to set the dimension of the ruler steps by the value control.
• Relative: Mode divides the ruler by a set division count.
• Value: only in Absolute ruler mode: distance between ruler marks
• Division: only in Relative ruler mode: number of ruler marks on edge or curve for snapping

Projection Snap

• Dir
• Ortho
• Both

Angle Snap

• ANGLE SNAP: Button enables this mode. Angle snap value can be set as na, 90º, 45º, 30º, 15º and 5º.
• Angle: User defined angle.

Grid

• LW: native LW grid snap.
• UCS: user defined snap grid.
  • Value: user defined grid size

Clear all: This button disables all of the snap settings.
