About the Draft User Interface
The Draft tab consists of commands, tabs, and shortcut menus. Click Model > Draft to open the Draft tab.
Commands
Draft Hinges collector—Displays the neutral lines or curves on the draft surfaces, that is, the lines or curves that the surfaces are pivoted about. You can select up to two planes, quilts, or curve chains. To select a second hinge, you must first split the draft surfaces by a split object.
Pull Direction collector—Displays the direction that is used to measure the draft angle. You can select a plane, a straight edge or a datum axis, or an axis of the coordinate system.
Reverse Pull Direction—Reverses the pull direction (indicated by an arrow).
Angle box—Changes the value for the draft angle.
Reverse Angle to add or remove material—Reverses the direction of the draft angle, to switch between adding and removing the material.
For split drafts with independently drafted sides, the tab contains a second Angle box and Reverse Angle button to control the draft angle on the second side.
 
* For Variable drafts, the Angle box and Reverse Angle button are not available.
—Automatically propagates the draft to surfaces that are tangent to the selected draft surfaces.
—Preserves inlying round surfaces as rounds. They will not be drafted.
Tabs
References
Draft surfaces collector—Displays the draft surfaces. You can draft only those surfaces that are formed by tabulated cylinders or planes. You can select individual surfaces or continuous chains of surfaces. The type of the first selected surface, solid or quilt, determines the type of other surfaces that can be selected as draft surfaces for this feature.
Details—Opens the Surface Sets dialog box to add or remove draft surfaces.
Draft hinges collector—Displays the neutral curves on the draft surfaces, that is, the lines or curves that the surfaces are pivoted about. You can select up to two draft hinges. To select a second hinge, you must first split the draft surfaces by a split object.
For each draft hinge, you can select a plane or quilt, in which case the draft surfaces are pivoted about their intersection with this plane or quilt, or a curve chain located on the draft surfaces.
Details—Opens the Chain dialog box to add or remove draft hinge chains.
Pull direction collector—Displays the direction that is used to measure the draft angle. You can select a plane, in which case the pull direction is normal to this plane, a straight edge or a datum axis, in which case the pull direction is parallel to this edge or axis, or an axis of the coordinate system, in which case the pull direction is parallel to this axis. Select the particular axis of a coordinate system, rather than the coordinate system name.
Flip—Reverses the pull direction (indicated by an arrow).
Split
Split options
No split—Does not split the draft surfaces. The whole surface pivots about the draft hinge.
 
* If you select No split, then the Split object collector and Side options are not available.
Split by draft hinge—Splits the draft surfaces along the draft hinge.
Split by split object—Splits the draft surfaces by using a quilt or sketch. If you are splitting by a sketch that does not lie on the draft surface, the system projects it on the draft surface in the direction normal to the sketching plane. If you select this option, the Split object collector is activated.
Split object collector—Displays the split object. Select a surface quilt, in which case the split object is the intersection of this quilt with the draft surface, select an external (existing) sketched curve, or sketch the split curve.
Define—Opens Sketcher so you can sketch the split curve on the draft surface or on another plane. If the sketch does not lie on the draft surface, the system projects it on the draft surface in the direction normal to the sketching plane.
Side options
Draft sides independently—Specifies two independent draft angles for each side of the drafted surface.
Draft sides dependently—Specifies a single draft angle, with the second side drafted in the opposite direction. This option is available only if the draft surfaces are split by the draft hinge, or for a split draft with two hinges.
Draft first side only—Drafts only the first side of the surface (determined by the positive pull direction from the split object), with the second side remaining in the neutral position. This option is not available for split draft with two hinges.
Draft second side only—Drafts only the second side of the surface, with the first side remaining in the neutral position. This option is not available for split draft with two hinges.
Angles
Angle table
Constant draft—Single line containing an Angle box that contains the value of the draft angle.
Variable draft—Additional lines for each additional draft angle. Each line contains an Angle box with the value of the draft angle, a Reference box with the name of the reference, and a Location box specifying the location of the draft angle control along the reference.
Split draft with independently drafted sides (both Constant and Variable)—Each line contains two boxes, Angle 1 and Angle 2, instead of the Angle box.
Adjust angles to keep tangency check box—Forces the resultant draft surfaces to be tangent. Not available for Variable draft. Variable draft always keeps surfaces tangent.
Options
Exclude loops collector—Displays contours to be excluded from draft surfaces. Available only when the selected surface contains more than one loop.
Exclude areas with draft check box—Excludes from the draft feature the areas where the angle between the draft surface and the pull direction is ≥ greater than or equal to the draft angle. Used in cases where the draft surface is not perpendicular to the pull direction, and the angle between at least part of the draft surface and the pull direction is ≥ greater than or equal to the draft angle.
Create round/chamfer geometry check box—For geometry that was attached with rounds or chamfers, recreates rounds or chamfers after attaching the drafted geometry.
Extend intersect surfaces check box—Tries to extend the draft to meet the adjacent surface of the model. If the draft cannot extend to the adjacent model surface, then the model surface extends into the draft surface. If neither of these cases are possible, or if you did not select the check box, a draft surface that overhangs the edge of the model is created. This option is not available if open surfaces are selected as draft surfaces.
Properties
Name box—Sets a name for a feature.
—Displays detailed component information in a browser.
Shortcut Menus
Right-click the graphics window to access shortcut menu commands.
Solid Surfaces—Selects all the solid surfaces of the model. Available only when the model has solid surfaces and one of the solid surfaces is already selected.
Draft Surfaces—Activates the draft surfaces collector and lets you select surfaces to be drafted. You can draft only those surfaces that are formed by tabulated cylinders or planes. You can select any number of individual surfaces or continuous chains of surfaces. The type of the first selected surface, solid, or quilt, determines the type of other surfaces that can be selected as draft surfaces for this feature.
Draft Hinges—Activates the draft hinges collector. You can select up to two planes, quilts, or curve chains. To select a second hinge, you must first split the draft surfaces by a split object.
Pull Direction—Activates the pull direction collector. This direction is used to measure the draft angle. You can select a plane, a straight edge, a datum axis, or an axis of the coordinate system.
Split Object—Activates the Split object collector.
Split by draft hinge—Automatically uses the draft hinge as the split object.
Make Constant—Makes the draft Constant. Available for Variable draft only.
Right-click a pull direction arrow to access shortcut commands.
Flip—Reverses the pull direction
Right-click the round handle connected to a draft angle to access shortcut commands.
Add Angle—Adds another angle control at a default location and with a most recently used draft angle value. You can modify both the angle value and location.
 
* Another way to add a draft angle is to hold down the CTRL key, click the round handle connected to a draft angle and drag it along the edge to the desired location.
Delete Angle—Deletes the selected angle control. Available only if more than one angle control is specified.
Right-click the square handle connected to a draft angle to access shortcut commands.
Flip Angle—Flips the direction of the draft at the selected angle control location. For a Split draft with independently drafted sides, you must right-click an individual angle cell for this option to be available.
Right-click the Angles tab to access shortcut commands:
Add Angle—Adds another angle control at a default location and with a most recently used draft angle value. You can modify both the angle value and location.
Delete Angle—Deletes the selected angle control. Available only if more than one angle control is specified.
Flip Angle—Flips the direction of the draft at the selected angle control location. For a Split draft with independently drafted sides, you must right-click an individual angle cell for this option to be available.
Make Constant—Deletes all the angle controls except the first one. This option is available for Variable draft only.
