Contour wizard

This command allows to quickly create the sketch contour. For example, after cleaning an Autocad imported sketch, it will be possible to retrieve its contour with this wizard and then extrude it.

Creation stages / Use:

Click the icon or select the 2D sketch > Contour wizard... command from the drop-down menu.

Select Path or Region.
Validate.

Path :

Select the first segment. Arrows on this segment allow to Invert, to continue on the left or on the right. The color of the arrow corresponds to the color of the icon in the dialog.

By clicking arrows in the workspace area, the path is defined until the next intersection. It is also possible to alternate the right side and the left side as needed.
By clicking the direction icon in the dialog, this direction will be taken in account on each intersection.

Imported sketch

The yellow arrow indicates the direction, the blue one the left.

Result by clicking on "all left" in the dialog

Imported sketch

In this case, you have to click the corresponding arrow to continue until the next intersection.

Result by selecting the path intersection by intersection.

Region:

Select background sketch. When the sketch contains internal and external contours, you have to click near the contour on which you want to create the contour. It is possible to click outside the part to create its external contour. On below examples, the cross represents the mouse click on the background sketch.

It is possible to start a contour with the region mode, then continue it with the path mode.

Available Options:

Detect real intersections:

If this option is checked, and if the support sketch entities are not joined by one point, but cross themselves, they will be taken in account (like the passing mode of the contour). If it is not checked, extremities must be coincident.

Modifications / Additional information:

If the wizard do not finish the contour (superimposed line, or other reason), you just have to edit the sketch and use this command again to continue the contour.
