New Part in Context

In this Task

• A new part will be drawn in context referencing points of geometry in Part 2.
• The new part will be drawn on the Part 2 model layer.

Associated Tasks

• Double Point Circle with 3D Thickness.

Before you Start

• Use your drawing which was saved in the previous Session or make use of the sample drawing for this Session. The previous Task/Tasks must be completed in order to continue with this Task.
• Relative coordinate mode should be activated.
• View is set to Iso_SE. Workplane is displayed and is set to Plane by World.
• Layer Part 2 is used to create the new part.
• Vertex snap is required.

Take Note

• When restoring a part to the graphics editor, make sure the Block is placed on the associated layer.
• It is not necessary to immediately explode parts which are inserted into the graphics editor from the Blocks palette. If is frequently easier to assemble Blocks rather than their constituent parts.
• At the completion of this Session, save your design to a name other than Assembly. It will be used again in the future sessions.
• After assembly parts, the sketch geometry can be deleted as the sketch for the part is retained in the Blocks palette.

 

New Part in Context

New parts can be created by referencing geometry in other parts. A new cylindrical extrusion will be added between the uprights of Part 2, shown below.

Workplane by Facet

Right click in the editor

This Workplane feature applies a Workplane to a selected facet (flat surface) of a 3D object.The Page Up and Page Down keys can be used to cycle between the available facets of the part.Workplanes can be placed onto a facet for single-instance applications using the Auto Workplane by Face tool.

Zoom into the upper part of the left upright of Part 2 when viewed in Isometric South East view, shown below.

Zoom in to the left upright of Part 2

Using the Workplane by Facet tool, place the Workplane onto the face shown below. Part 1 layer switched off for illustrative clarity only.

Double Point Circle with 3D Thickness

Ribbon : Draw | Draw 2D | Circle/Ellipse | Center & Point

Default Menu : Draw | Circle | Center & Point

Palette : Sketch | Circle/Ellipse | Circle Center & Point

Right click, select Properties | 3D | Thickness

All 2D circle tools provide options to generate these objects according to specific criteria such as radius, diameter, tangential connections etc. For example, a circle can either be drawn from a center to a radial point, from 2 points on the diameter or by connecting 2 tangential points to other circles or lines.The geometrical and spatial information, as well as the properties (layer, color, line style etc) for any drawn object can be found using the Selection Info Palette. For example, the radius of a circle can be changed by selecting the circle and viewing the information in the Selection Info Palette.Similarly, geometric information, for example, changing the radius or a circle be done using the Metrics pane of the Selection Info Palette.

Any 2D sketch object can be drawn with a pre-set 3D thickness. In this instance, a circle with a pre-set 3D Thickness will be inserted so that it creates a cylindrical extrusion.

Select the Double Point Circle tool, set another color for layer Part 2 Model, then right click in the editor and select the Properties Sheet.

Select the 3D page, then input a value of 78 into the Thickness field. In this case, the value of the ‘extrusion’ will be positive 78 as a result of the direction of the Z axis, shown in the illustration above.

Activate as current the Part 2 Model layer, then activate the SNAP tab at the base of the editor.

Take Note

Objects can be inserted by snapping to points of geometry that are in a parallel plane to the Workplane, but the object will be placed on the Workplane, irrespective of the view.

---

Turn the view to Right, then zoom into the area shown below.

Using the vertex points on the top edge of the void on Part 2, insert the circle, allowing the vertex snap to magnetically track to the correct vertex points shown by the pins below.

Inserting the 3D Circle onto vertex points using the RIGHT side view.

Return the view to Isometric South East. The result is shown below.

 

New 3D Circle inserted

Always view the model from different viewpoints to check the positional accuracy of new objects.
