Solid Vision TM 2007Case study

1. Overview

In this Case Study, we will make a solid model (shown in the right picture) from an incomplete scan data (shown in the left picture). We will be mainly using the functionalities in Polygon , Curve and Surface workbenches.

Scan Data Solid Model

2. Data files

Cover.Stl

– The file contains the original scan shell

3. Summary

 Step1: Region Group

 Step2: Align

 Step3: Curve Network Creating

 Step4: Surface Creating

 Step5: Trimming surface

 Step4: Shell (wall thickness) to Create Solid Model.

4. Modeling Process

 Step1: Region Group

1. Open ” cover.stl

You can import mesh data using insert>import. Select file cover.stl file

2 .

Region Group

1. Click the Region Group on the toolbar to enter region group mode. Click segment & Click ok button. It separates similar areas as coloured regions .

Auto

2. Exit Region Group Mode.

Click the button in the bottom right of the graphic area to exit region group mode.

 Step2: Align.

1. Create ref. Geometry

Click on add ref. plane or insert>ref. geometry>plane.

Solid Vision TM 2007Case study

Select region as shown & click ok.

Similarly click on ref. vector or insert>ref. geometry>ref. vector.

Select region as shown & click ok.

2. Align Wizard

Click the (Align Wizard) on toolbar or Tools>Align>interactive setup.

Click on next stage button

.

Screen splits into 2 windows.

In moving icon, select plane1 in plane option & vector1 in vector option.

In target icon, select “to origin”.

Click ok to align scan data.

 Step3:

Curve Network Creating

1. Creating ref. plane

Hide front & right ref. planes from model tree.

Click on add ref. plane.

Select method as offset

Select top plane as shown.

Click ok button.

2. click on mesh sketch or insert>mesh sketch

Select plane 3 as shown, click ok

Solid Vision TM 2007Case study

Sketch window is open.

Create arc as shown. Maintain length & click ok.

Similarly create remaining arc.

Proceed with same procedure by picking front plane as shown & create arc.

Solid Vision TM 2007Case study

Similarly create all side curves as shown for constructing loft & sweep surface

3. create primitive surface click surface primitive or insert>surface>primitive

Select region as shown in fig. & toggle on plane option in shape to create.

Select to done.

Similarly select magenta region to create planar surface.

4. creating revolve surface

Solid Vision TM 2007Case study

Click ref. plane or insert>ref. geometry>ref.plane

Select entities vertice & vector1

In method prompt pick point & coplanar axis.

Click to done.

5. click on mesh sketch or insert>mesh sketch

Select plane shown in fig as base plane.

Construct curves by same procedure

Click to done.

Step4: surface creation

1. create loft & sweep surface,revolve surface.

click surface loft or insert>surface>loft

select curves as shown in fig

Click to done.

Click sweep or insert>surface>sweep

Select profile & path as shown in fig.

Click to done.

Solid Vision TM 2007Case study

Similarly create remaining all sweep & loft surface as shown

Creating revolve surface

 Step5: Trimming surface

1. click on trim surface or insert>surface>trim

Select tool entities & target entities.

Click on remaining bodies.

Click to done.

Result body as shown in fig.
