You can create line by several construction types. Click View, Geom Curve to toggle the display of individual curve.
To create a point:
Click Line(Curve toolbar) or click Geometry, Curve, Line.
In the dialog , select the type of you want to create the line:
Parameters. Create a line by two points' parameters. You can also sketch lines onto any plane when "Sketch" is checked.
Point/Point. Create a line or multiple connected lines by select points in order. If more than two points selected, you can check "Closed" to make the loop close. If lots of unsort points are area selected into the listbox, you can check "Sort Points" and it will automatically sort points according distance gap.
Point/Axis. Create a line by a point and a direction, the distance define the length of the line segment. If the distance is negtive, the line direction will be reversed. "Project" option will project the selected points to the selected edge/direction vector, and the results are line segments.
a. Project points to line. |
b. Two lines |
Point/Circle. Create two lines which pass the point and tangent with the circle. The selected point must locate at the plane of the circle.
a. Vertex and circle. |
b. Two tangent lines |
Circle/Circle. Create lines which tangent with two circles. If two circles intersect with each other, it will also create the intersecting line. The selected two circles must locate at the same plane. "Centers Line" will make a line segment between two centers of circles.
a. Two circles |
b. Create 3 lines by two circles |
a. Select two lines. |
b. Create two middle lines. | c. Result after checking "Middle Curve Line". |
a. Fit a line by points |
b. Fit a line by checking "Whole Edge". |
