Lab Exercises

Exercise 1: Completing the Bottle Design Exercise 2: Completing the Upper Body of the Shaver Exercise 3: Creating the Shaver Head Cover (Challenge) Exercise 4: Completing the Lower Body of the Shaver (Challenge)

IntroductionSurfaces are used to define the complex shapes that you cannot define using solid modeling tools. You can merge the surfaces to create quilts. You can then create solids using the quilts as references by using editing tools such as Solidify and Thicken. The process of converting the quilts to solids requires you to add material thickness. Adding thickness can lead you to limitations when you try to apply the feature. You may not be able to add thickness beyond a particular dimension, due to the geometry of the surface.You can also use quilts to modify existing solid surfaces or use them to cut solids in design models. Also, in complex situations where standard solid rounds and chamfers do not provide satisfactory results, you can create fillets using surfaces.

ObjectivesAfter completing this module, you will be able to:

Replace a solid surface with a quilt. Patch a solid surface with a quilt. Create cuts using quilts. Create rounds and chamfers as surfaces instead of solids.

Page 2: ProE Surfacing - Module 11

Creating Solids Using QuiltsSurface geometry can be converted to solid geometry in the following ways:

Thickening surfaces – Material is added to either or both sides of the surface using the Thicken tool from the Edit menu.

Solidify closed quilts – If the quilt is closed, with no gaps at the edges, you can add material to the inside of the quilt using the Solidify tool from the Edit menu.

Solidify quilts intersecting the model – When a quilt intersects with the solid geometry such that there are no gaps or openings, the engulfed volume can be filled with material using the Solidify tool from the Edit menu.

Creating Solid Geometry from SurfacesThickening surfaces

The first set of figures show the open surface being thickened using the Thicken tool.

Solidify closed quilts The second set of figures shows the closed quilt being solidified using the

Solidify tool.Solidify quilts intersecting the model

In the third set of figures, the desired shape has been visualized over built surfaces. These are merged to form the desired quilt. The quilt is then merged with the solid using the Solidify tool.

Replacing Solid Surfaces You can replace an entire solid surface using the Replace option in the

Offset tool. Surface replacement differs from protrusions and cuts because it can add

material in some places and remove it in others. Surface replacement is a surface deformation feature and creates a

separate feature.Guidelines to use the Replace option:

If the replacing quilt does not extend beyond the boundaries of the existing solid, the system interpolates the existing surface, sometimes leading to undesirable or unexpected results.

If surface replacement adds material in some places and removes it in others, then the replacement quilt must consist of one surface only.

3

Page 4: ProE Surfacing - Module 11

Surface replacement cannot be done in the Assembly mode as an assembly feature.

It is not recommended to create two replacement features on top of each other. It is good design practice to delete one replacement quilt before creating a new one. Or, you can redefine the existing tweak/replace feature such that it replaces a different surface or uses a different replacement quilt.

A quilt that has replaced a feature's surface cannot, in turn, be replaced by another quilt. The replacement surface must be deleted first.

About the figures In the first set of figures, the selected surface of the solid block is

replaced with the selected quilt positioned above it, resulting in the figure on the right.

In the second set of figures, the Replace tool is used to add and remove material at the same time.

The third set of figures shows the replacement, using a quilt that partially covers the solid surface. 

Replacing Solid Surfaces (cont.) This slide displays an example of how to use the Replace option in the

Offset tool to create a smooth shaped button. You start by creating the approximate shape of the button using a solid

feature such as an Extruded protrusion. You also create a quilt using surfacing techniques that will be used to

create the final shape of the button. You select the solid surface to be replaced, as shown in the first figure.

4

Page 5: ProE Surfacing - Module 11

Next, you use the Replace option and the quilt as a reference to replace the solid surface, as shown in the second figure.

The resultant solid will have the smooth shape of the quilt in place of the original solid surface, as shown in the third figure.

Patching Solid Surfaces You can use the Patch option in the Solidify tool to replace a specified

portion of a surface or surfaces with a quilt. All the boundaries of the replacement quilt must lie on the surfaces that you are patching. The patch feature can add or remove material using a single surface definition.

This feature differs from the replace feature as it can affect more than just one solid surface. You can use it to add or remove material from portions of solid surfaces or the entire solid surface.

5

Page 6: ProE Surfacing - Module 11

Cutting Solids Using QuiltsYou can use open or closed quilts to cut solids.

Using open quilts to cut away a solid – You select a quilt as the cutting entity and you remove all material on one side of the quilt. You use the Solidify tool to access this functionality.

Using open quilts to create a thin cut – Similar to the first method, you select an open quilt as the cutting entity. However, in this case, you make a cut using the Thicken tool. For example, you can remove material a specific distance from either side of the cutting quilt, or symmetrically about the cutting quilt.

6

Page 7: ProE Surfacing - Module 11

Using Surfaces to Create Rounds and Chamfers You can create rounds and chamfers as solid features or surface features.

The default is to create them as solid features. During design, it is sometimes convenient to create these features as

surface type features instead of solid features. The primary benefit of this technique is to enable you to edit the surface before the creation of the round or chamfer, adding a great amount of flexibility to this type of geometry creation.

This is especially useful in situations where a round/chamfer would normally fail. In this case, you can create the round/chamfer as a surface, manipulate the resulting surfaces, and finally, create a solid feature using the surface for a protrusion, cut, replace, or patch.

The figure above is intended for illustration purposes only. In this case, a round will

automatically produce the result shown on the right.

Scenario

You continue to create the lower body of the shaver. Unlike the upper body, in this case a series of steps have been performed for you. Geometry has been copied from the BODY_MASTER, and a surface for the switch base has been added. The first step in detailing it is to add thickness to the part.
