AlarvyCAD Turn Module
ALARVY Turn module contains multiple features specifically to create 3D CAD models of turned parts or revolved parts or parts that can be manufactured in lathes and turning centres.
1. TURN
TOOLBAR
Fig 1.1 Turn Toolbar
ALARVY Turn module comes with the following features
I. Revolve
II. Subsection
III. Groove
IV. Step
V. Fillet
VI. Chamfer
VII. Hole
VIII. Thread
1.1 REVOLVE
Fig 1.1.1 Revolve button
• On clicking the Revolve button, it automatically shows the Top view.
• It already has an axis and no need to draw an axis like other modelers.
• It requires only half sketch so that it can revolve the sketch about 360 degrees.
• The sketch can contain lines and arcs.
• It allows only a closed sketch to be created and hence the sketch uses the last point of the first entity as the start point of the next entity.
• There is no separate sketcher and 3D model view in AlarvyCAD. Both are integrated.
• By default, Grid, Horizontal Constraint, Vertical Constraint, Grid Snap are ON.
• On clicking Revolve, after clicking the first point, sketch entity tool bar appears in the right to choose line or arc or inverted arc or 3 point arc or to close the sketch. Note that line option is on by default. Refer Fig 1.1.2 and Section 1.1.1
• The sketch requires a minimum of 3 points or 2 entities (lines/arcs) to close the Sketch.
• Keyboard shortcuts for various buttons are given in brackets: Line (L), Arc (A), Invert (I / down arrow), 3 Point (3) and Close (C / Esc).
• On every click of a point in the Sketch, Diameter and Length dimensions will automatically appear for each point.
1.1.1 Sketch
Entity Tool Bar
Fig 1.1.2 Sketch entity tool bar
- On
clicking the Revolve or Subsection button, sketcher mode is turned On.
- In
Sketcher mode, only 2d sketch is shown in top view.
- After
adding first point to the sketch, Entity toolbar appears in the right,
next to side toolbar.
- This
allows the user to select a Line segment or Arc or Inverted arc or 3-Point
Arc to be drawn to the next point of the sketch.
1.1.1.a Line Segment
· Adds a line from the previous added point to the current mouse position.
· Refer Fig 1.1.3
Fig 1.1.3 Line segment
1.1.1.b Arc
· Adds an arc from the previous added point to the current mouse position.
· It is initially drawn such that the first point is tangential to the previous entity (lines/arc). In other words, tangent continuity is maintained initially. Refer Fig 1.1.4 and 1.1.5.
· On editing the arc dimensions, the tangent continuity may not get maintained depending on the dimensions.
· For an arc, the dimensions shown in black in the Fig 1.1.6 defines the arc: start diameter, end diameter, arc radius and length between the first and last point of the arc.
Fig 1.1.4 Arcs while sketching maintaining tangential continuity
Fig 1.1.5 Arcs while sketching not maintaining tangential continuity
Fig 1.1.6 Arcs after sketching
1.1.1.c Inverted Arc
• Inverted arc is initially drawn such that the first point is not tangential to the previous entity (lines/arc) and is inverted with respect to a tangential arc.
• Refer Fig 1.1.7 and 1.1.8.
Fig 1.1.7 Creation of inverted arc
Fig 1.1.8 Creation of inverted arc
1.1.1.d 3 Point Arc
• A 3 Point Arc is defined by 3 points through which the arc passes. In Fig 1.1.9, the first point of a 3 Point Arc is the last point of the previous line and the second point is shown as the end point of a dashed line.
• On clicking the third point, the arc appears as shown in the Fig 1.1.10.
• For a 3 Point Arc, the dimensions shown in black in Fig 1.1.11 defines the arc: start diameter, end diameter, arc radius and length between the first and last point of the arc.

Subsection Sketcher mode:
· A 3D Model can be edited in sketcher mode.
· In sketcher mode, model is shown as a 2d sketch.
· Red point is seen on mouse move. It turns blue when it is over any edge of the model.
· On mouse click, first point of subsection is added to the sketch along with dimensions.
· Second point of subsection cannot be on the same edge of the model.
· On mouse move, a line segment is shown starting from previously added point.
· There is an entity tool bar next to side toolbar in right which has an option to choose Line, Arc, Inverted arc or 3 point arc. Line is default option.
· Based on selected option, same is drawn from previously added point of the sketch to the current mouse position.
· With subsequent clicks, others points are added to the sketch with corresponding dimensions.
· Last point of subsection should be on the revolve sketch edge to form a closed sketch.
· Once a closed sketch is created, it exits sketcher mode and 3D Model is shown.

AlarvyCAD Threads shown
in Fig 1.8.2 are using virtual representation showing the helical structure. In
reality, threads have grooves in them. Actual thread representations are
avoided to make the profile lighter and rendering easier.
