General Enhancements in Sketch

Variable Pitch Helix

The Helical Curve command now supports creating a helix with a variable pitch.

Previously with 3D Sketch tab Create panel Helical Curve, you could only create a helix with a constant pitch. Use the new Variable helical curve option in the command to specify multiple Pitch, Revolutions, Diameter, and Height values. You can use the variable helical curve as a guide in the Loft command or as a Path in the Sweep command.

Tip: Check out the new Create a Variable Pitch Helix tutorial in the gallery.

For more information about the Helical Curve command, see To Draw 3D Curves.

Drawing Sketch Autoproject

The Application Options/Sketch tab setting, Autoproject edges during curve creation, ​now behaves the same in a drawing view sketch as it does in a part sketch.

In a drawing view sketch with Autoproject edges during curve creation selected:

  • Pausing the cursor over and around a drawing profile with a sketch command active no longer projects the profile. You must now click the profile to project the profile.
  • While hovering the cursor over an edge, a highlight preview shows and then a black projected curve graphic displays.
  • Deselecting Autoproject edges during curve creation in Application Options/Sketch tab when a sketch is active now takes effect immediately. You no longer need to exit and re-enter the sketch environment for the change to the command to be enabled.

For more information on inserting images into a sketch, see To Project Geometry into a 2D Sketch.

Image Property Enhancements

You can now render images with unchanged alpha values (Alpha transparency) and specify a transparency color.

The Image Property dialog box is enhanced with the following new settings:

  • Set Chroma Key: Select to specify a transparency color.
  • Use Image Alpha (only available if the image supports alpha layer): Combines the background with the image using the alpha layer of the image.

As a result, quality of the rendered image is improved.
