In this issue, the editor will bring you about how to draw splines for CAD parameters. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

In CAD design, you need to draw splines, and you can set properties such as spline weight and color.

The function description is mainly used:

_ DMxDrawX::PathLineTo

Moves the next point of the path to the specified location. The details are as follows:

Parameter indicates the X coordinate of the DOUBLE dX point, the Y coordinate of the DOUBLE dY point _ DMxDrawX::DrawPathToSpline

Turn the path into a spline.

Code description for implementation in js:

Function DrawSpline () {/ / change the color back to black and white mxOcx.DrawCADColorIndex = 0; / change the linetype to solid mxOcx.LineType = ""; / / set the lineweight 4 mxOcx.LineWidth = 0; / / create a layer named "SplinelineLayer" mxOcx.AddLayer ("SplinelineLayer"); / / set the current layer to "SplinelineLayer" mxOcx.LayerName = "SplinelineLayer" / / "- -" / / define the start point of a path mxOcx.PathMoveTo (0, 1700) with a spline drawing a solid line; / / the next point of the path mxOcx.PathLineTo (1700) / / the next point of the path mxOcx.PathLineTo (1800); / / the next point of the path mxOcx.PathLineTo (0, 1800); / / synthesize the path into a sample line mxOcx.DrawPathToSpline () / / "- -" / / use the spline mxOcx.AddLinetype to draw a dashed line ("MySplineType", "30 MySplineType"); mxOcx.LineType = ("MySplineType"); mxOcx.DrawCADColor = 255; mxOcx.LineWidth = 5 / / define the start point of a path mxOcx.PathMoveTo (200,200); / / the next point of the path mxOcx.PathLineTo (1700); / / the next point of the path mxOcx.PathLineTo (1800); / / the next point of the path mxOcx.PathLineTo (1700); mxOcx.DrawPathToSpline (); mxOcx.ZoomAll (); mxOcx.UpdateDisplay () } above is how to draw splines with the CAD parameters shared by the editor.
