Snap

Tip: When youre finished using snaps,its good to disable them to avoid

confusion, especially for beginners..

Snaps help to increaseaccuracy and precision

when modeling.


10/47

Snap to Endpoints

The white cross turns tored when you are within

snap range.

When interactivelyplacing points, a white

cross appears.

Snap

Snap to Endpoints will snap any entity to the endpoints of curves. .

Snap to MidpointsSnap

Snap to Midpoints will snap any entity to the midpointof curve segments. .

12/47

Snap to Points

Snap to Points will snap an entity to:- Control points of curves and surfaces- Endpoints of curves- Midpoints of curve segments- Center of circles, arcs, and ellipses

Snap

Black dots indicate possiblesnap points.

Snap to CurveSnap

snap to curvesand tangents = ALT

Snap to Curve will snap any entity to the closest pointon the nearest curve. .

File : 29-Snap to Curve and Tangent.evo


14/47

Snap to TangentSnap

The tangent appearsas a red dotted line.

Snap to Tangent will snap any entity to the tangent ofthe nearest curve.

File : 29-Snap to Curve and Tangent.evo


15/47

Snap to Tangent

Now move the second pointusing Snap to Tangent untilyou reach the red dotted line.

To achieve tangency at the endof a NURBS curve, you need to

align the last two points.

Snap to tangent requires adestination curve.

Move the endpoint of onecurve and snap to the end of

the second one using theSnap to Endpoint .

Snap in 3D

It allows snaps to work inthree dimensions.

Snap

Snap in 3D is not a snap itself.It is an option for any snap.

File : 30-Snap in 3D.evo


17/47

Surfaces

Every point on the surfacehas specific coordinates:

U and V

A NURBS surface is like asheet of paper with no

thickness.

uv

Surfaces

U and V are similar to cartesiancoordiantes, but lie on the

surface which is often curved.

Make Manifold

MANIFOLD SOLID

Surfaces

File : 32-MakeManifold1.evo

The Make Manifold tool allows you to select aseries of surfaces and trim the excess parts so

that the result is a closed solid.

Surfaces

Files : 34-Intersect.evo

The Intersect tool allows you to select faces to remove

from the intersection of multiple surfaces, resulting in asingle surface.

Any excess partsare removed.


24/47

Exercise: Intersect

Remove excess parts of the legs that areprotruding into the body.

Surfaces

File : 35-Lamp2.evo


25/47

Intersect vs Make Manifold

Intersect- The objects to intersect do not have todefine a closed region.

- You can manually select what faces toremove.- The result is not necessarily a solid.

Make Manifold- The objects to intersect must define aclosed region.- All excess faces are automaticallyremoved.- The result is a solid for sure.

Surfaces

The Intersect tool is more powerful and flexible, while the Make Manifold

tool performs automatic intersection in specific use cases.

Boolean Operations

Intersection

Union

Subtraction has two options:

- Object 1 minus Object 2- Object 2 minus Object 1

27/47

The Blend Surface tool generates asurface that connects two edges of twoseparate surfaces. Each edge can be

made of many peices.

Blend Surface

Click on edges near thesame side to avoid twisting.

Surfaces

File : 37-BlendSurface.evo

Set the Quality to 10 ifthe shape or precision is

not good enough.

MultiSweep

rail curves

Surfaces

File : 38-MultiSweep.evo

Use the MultiSweep tool to sweep

one or more profile curves along oneor more rail curves.

Skin

Use the Skin tool to fit asurface to a series of

profile curves.

Interpolation MethodsSkin: The surface passesthrough the profile curves.Spline: The surface follows thecurves without passing through.

34/47

Multisweep vs Birail vs Skin

Multisweep - Supports multiple profiles and rails- Profile curves must intersect rails- Curves must be attached

Birail- Requires one profile and two rails- Curves dont need to be attached

Skin - Requires two or more profile curves- No rail or guide curves- Curves dont need to be attached

Loft 8.5Surfaces

The Loft 8.5 tool is similar toPipe , but allows you to use

multiple profile curves tocreate a variable shape.

handle many profilecurves and also follows a

rail curve.

Note : If an edge is split into severalpeices, you may need to have two

identical radii (one on each end) in orderto achieve a variable radius round.
