(Available in all TurboCAD Variants)

The Modify tools are generally used to change the shapes of existing objects. These tools do not change physical properties such as layers or line widths; rather they modify the actual geometry.
You can display the Modify toolbar by right-clicking in any toolbar area and selecting Modify.

Some Modify tools require input of two or more objects. If you are working in 3D, all 2D objects selected for modification must lie on the same workplane . To change an object’s workplane

(Available in all TurboCAD Variants)

Default UI Menu: Modify/Arc Complement

Ribbon UI Menu:

Reverses the start and end angles of an arc. In other words, the arc will become the portion of the original circle that was cut.

1. Select the arc you want to modify.

1. Click anywhere to create the arc complement.

Tip: When using this tool on arcs that are the result of exploding a polyline, or created as the result of using the Arc Divide option of the Edit Tool, this tool may select more than one arc at a time. If this happens, move the arcs from each other.

Chain Polyline

​

(Available in Platinum, Professional and Deluxe)

Default UI Menu: Modify/Chain Polyline

Ribbon UI Menu:

Connects intersecting objects or portions of objects into a single polyline. A chain of connected objects is created, starting from a selected object and proceeding in a specified direction.

Note: The difference between this tool and the Auto Joining option of Join Polyline is that Chain Polyline enables you to create a partial chain, and to work with overlapping objects.

1. Select the object from which the chain will start.

1. Set the direction in which the chain will proceed.

1. If overlaps are encountered, you must specify the path to continue the chain.

1. The chain proceeds until it reaches the last object, and the polyline is created.

If you do not want the chain to proceed all the way to the last object, you can select Finish from the local menu or Inspector Bar at any time.

Note: The original objects remain in the drawing.

Chamfer

(Available in all TurboCAD Variants)

Default UI Menu: Modify/Chamfer

Ribbon UI Menu:

Connects two lines (single or double lines) with a beveled corner. The selected objects do not have to intersect, and they can overlap.

Note: The resulting objects are separate line segments, unless the Polyline option is used, in which case the result is a polyline.

If the objects overlap, they will be trimmed to create the chamfer. Be sure to select the side of the object you want to remain.

There are three methods for creating chamfers: Distance / Distance, Distance / Angle, and Length / Angle. For all methods, the same local menu options are available.

Local menu options:

Polyline: Chamfers all corners of a polygon or polyline in one step.

1. Enter the chamfer distances, angles, or length in the Inspector Bar.
2. Select the multi-segmented object you want to chamfer.
3. Select Polyline from the local menu or Inspector Bar.

The chamfer is applied to all corners. The resultant object is one polyline.

Warning: Be careful when using the Polyline option with different chamfer distances. The results will not be symmetric.

The other local menu options apply to double lines.

Chamfer Distance – Distance

​

The chamfer is created by specifying its length along each line.

1. Enter both chamfer distances in the Inspector Bar. These are the distances along the lines that are to be chamfered. Distance A will be applied to the first line you select.

1. Select the first line to chamfer.

​

​ 3. Select the adjacent line. The corner is chamfered.

​

Chamfer Distance – Angle

​

The chamfer is created by specifying its distance along one line and its angle from the second line.

1. Enter the distance and angle in the Inspector Bar. The distance is measured along the first line you select.
2. Select the first line to chamfer.

​

​ 3. Select the adjacent line. The corner is chamfered.

​

Chamfer Length – Angle

​
The chamfer is created by specifying the total chamfer length (as opposed to the distance along the lines) and chamfer angle.

1. Enter the length and angle in the Inspector Bar. The length is the total length of the diagonal chamfer line.

​ 2. Select the first line to chamfer.

​ 3. Select the adjacent line. The corner is chamfered.

Double Line Options

(Available in all TurboCAD Variants)

You can specify how to create intersections of double lines, and whether cut lines and gaps will occur at the intersections.
For example: if you form a clean T-intersection of two double lines at an angle other than 90 degrees, the end of one of the first line will be cut at an angle, and the second double line will have a gap to accommodate the first double line.
Cleanup: Forms a clean intersection.

If you deselect Cleanup, the first line selected will remain unbroken.

Drop CutLines: Removes the cut lines in the first line, to even out the end of the line.

Drop Gaps: Fills in the gap in the second line.

Fillet

​

(Available in all TurboCAD Variants)

Default UI Menu: Modify/Fillet 2D

Ribbon UI Menu:

Connects two lines (either single or double lines) or arcs (except elliptical arcs) with a smoothly fitted arc. The filleted objects do not have to intersect, and they can overlap. The result is a rounded corner.

Note: You can also fillet corners with the Edit Tool . To apply fillets to a 3D polyline.

1. Enter the fillet radius in the Inspector Bar.
2. Select the first line or arc to fillet.

1. Select the adjacent line or arc. The corner is rounded.

1. If the objects overlap, they will be trimmed to create the fillet. Be sure to select the side of the object you want to remain.

Local menu options:

Polyline: Fillets all corners of a polygon or polyline in one step.

1. Enter the fillet radius in the Inspector Bar.
2. Select the multi-segmented object you want to fillet.
3. Select Polyline from the local menu or Inspector Bar.

1. The fillet is applied to all corners.

1. To Lines and Arcs: The resulting object is broken into lines and arcs. (The default, To Polyline, leaves the filleted object as a single object, even if the objects were originally separate.)

1. In Select mode, you can verify that the fillets are separate objects.

The other local menu options apply to double lines.

Note:You can use Fillet on splines and Beziers, however the extension will be straight element of the curve, not curved continuations as they are with arcs.

Note:You can use Fillet to change an arc on a polyline, but only on arcs that are between two straight segments. Simply select the two straight segments and the arc will be adjusted to the radius of the fillet.

Ribbon UI Menu:

Divides an object into two separate objects. This tool works on any single-line or double-line object, as well as on circles, arcs, and curves. You can split by using the cursor, or by specifying a ratio in the Inspector Bar. The ratio is the length of the first resulting segment to the length of the second resulting segment. The first segment starts at the start point of the object, which depends on how the object was created.

Splitting Lines and Double Lines

1. Select the line or line segment you want to split.

1. Position the split indicator where you want the split, or enter the split ratio in the Inspector Bar.

1. Click to locate the split. A temporary red X indicates the location.

Y

You can verify that the line is now two separate objects by selecting one of the lines.

To split a closed object such as a rectangle or polygon, you need to create at least two splits. For each one, click on the segment you want to split.

When splitting a polyline, you place the split on one segment (line or arc), but the entire polyline is split at the selected point.

Splitting Arcs and Circles

1. Select the circle, arc, or arc segment you want to split.

1. Position the split indicator where you want the split, or enter the split ratio in the Inspector Bar.

Thick Profile

​

(Available in Platinum, Professional and Deluxe)

Default UI Menu: Modify/Thick Profile

Ribbon UI Menu:

Draws grid(s) of lines/polylines/circles/arcs on plane. It is a another convenient way to create 2D profiles (closed objects with area) from polylines and curves.

You can take either an open or closed 2D Line, Arc, Polyline, or Curve (Spline or Bezier) and ‘thicken’ the profile of that entity by defining a distance on both sides of that entity where that thickening will occur.

Apply thick profile tool with defined width and corners type options to groups of entities

As result user gets set of polylines, set of connected polylines (these two options are for TC versions without ACIS), region or set of sheet ACIS entities (those two are for Pro Platinum)
Received entities can be used for extrudes/thick profile.

Note: The Thick profile tool automatically calculates thicken profiles accordingly to width defined for original entities

For example:

1. Apply to a closed Polyline

Original closed polyline with line and arc segments:

​

After Thicken Profile (of 15 mm each side) applied and vertices filleted:

After clicking ‘Finish, final Thick Profile object:

1. Apply to an open Arc

Convert to Curve

​

(Available in all TurboCAD Variants)

Default UI Menu: Modify/Convert to Curve

Ribbon UI Menu:

Converts a 2D object into a Bezier curve. Any single-line 2D object can be converted. Objects like double lines, dimensions, and text must be exploded first before converting.

1. Start with a 2D object such as a polyline. This example uses a polyline consisting of both linear and arc segments.

If you select the polyline and view the Selection Info Palette, you can see the object’s type.

\2. To convert the polyline, select it and activate the Convert to Curve function. The Tolerance value sets the precision of the conversion; a small tolerance means high precision, and therefore more control points available for node editing.

The polyline is replaced by a Bezier curve. This can be verified in the Selection Info Palette.

If you edit the curve with the Edit Tool, you can see the control points available for changing the curve’s shape. (For details on Bezier options, . This curve used a low precision (Tolerance = 0.1).

This curve used a higher precision (Tolerance = 0.001).

Nodes and control points can be moved to change the curve’s shape.

Convert to curve also works on 2D objects that are converted into 3D by entering a thickness in the 3D page of the Properties.

Sharp corners will remain sharp when two adjacent line segments cannot be approximated by an arc within the specified tolerance. This could happen when the vertex is too "sharp" which is defined by vertex angle, line lengths, and tolerance.

Convert to Arc Polyline

(Available in Platinum, Professional and Deluxe)

Default UI Menu: Modify/Convert to Arc Polyline

Ribbon UI Menu:

Converts a 2D object into a Polyline composed of arcs. Any single-line 2D object can be converted. Objects like double lines, dimensions, and text must be exploded first before converting.
