Solid Vision TM 2007Case study
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
Cover.Stl
– The file contains the original scan shell
Step1: Region Group
Step2: Align
Step3: Curve Network Creating
Step4: Surface Creating
Step5: Trimming surface
Step4: Shell (wall thickness) to Create Solid Model.

.
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:
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.
