Click Close to connect the current vertex to the first vertex and create a closed spline.Repeat steps 2 and 3 for each additional vertex.Click Add Point to add a vertex to the current line at the specified coordinate.On the Keyboard Entry rollout, enter values in the X, Y, and Z fields to specify a vertex coordinate.
To create a Line spline from the keyboard: Angle Snap need not be enabled for this feature to work. The angle for each new segment relates to the previous segment, so the angle snap works only after you've placed the first two spline vertices (that is, the first segment). To set this angle, go to Tools menu Grids And Snaps Grid And Snap Settings, click the Options tab in the Grid And Snap Settings dialog, and change the value in the Angle (deg) field. Hi Hope you are doing great I am Certified Experienced Mechnical Design Engineer with more than 6 years experience and having solid commands in CAD /3D Modeling. Nothing obvious will appear on the model at this point but you will see the effect of the 'cover' in the next step. This will create a copy of the vertices and edges of the select polygons in their current location. While creating a spline with the mouse, press and hold to constrain new points to angle increments determined by the current Angle Snap setting. Step 5: With every 4th row of polygons still selected, choose Tools -> Polygon -> Cover.Use the default Initial type setting of Corner and click all subsequent points to create fully rectilinear shapes. While creating a spline with the mouse, press and hold to constrain new points to 90-degree-angle increments from previous points.These two options aid in creating regular shapes: To create a line using rectilinear and angle-snap options: Click the first vertex and click Yes in the "Close spline?" dialog to create a closed spline.Go to the Create panel, click (Shapes), then click the Line button.Ĭlicking creates a corner vertex dragging creates a Bezier vertex.Adjusting spline tension automatically converts that spline to the Minimum Energy fit method. Drag the slider toward 100 to tighten the curve drag toward 0 to make it loose (more open). To adjust spline tension, right-click the spline and choose Spline Tension.Interpolation splines that use the AutoCAD fit method do not have handles and are not suitable for creating class A surfaces. Because Minimum Energy splines contain more data, surfaces generated using them take longer to calculate and create larger files. Creates smooth curves with high visual appeal and better curvature distribution.
Creates curves with smooth continuity between points.
