Rhino WIP Feature: Shapes in linetypes

Serengeti (Rhino WIP)
1

This is very very early in development, but there is enough in place for people to try it out and start providing feedback.

Rhino 9 linetypes now support shapes positioned at intervals along curves.

Here is the associated 3dm file

linetype_shapes.3dm (43.1 KB)

Creating these linetypes is still pretty rough, but hopefully we can improve the process over time. There is a new test command called

TestLinetypeWithShapes

This command lets you name a new linetype, define the shape spacing and if a gap should be made where the shapes exist. You then would select curves and/or text to define the shapes. Once you have a new linetype, assign that linetype to a curve to see it. I’ll try to record a small demonstration of this sometime this week.

Thank you! I know this has a been a long requested feature, particularly from the autoCAD crew but helps all!

EDIT:

In the example with the breakline, does the “breakline shape” inherit the linetype properties that it is part of? or do the shapes in linetypes have their own linetype properties such as color, print width, etc?

Color and width should be inherited, but it’s so early on I haven’t even tried that out yet. I do know taper and dash pattern is currently not inherited as can be seen in the pac-man linetype

Don’t forget to make this “curvepiping” friendly!

I’m thinking that would be useful also for rendering purpose such sewing on SRF.

Hi @stevebaer , thank you for adding this feature.

However, there are some issues I have noticed. You can find them below.

1- The base curves I have marked with an arrow are visible.

2- The screenshot below shows the linetype created in AutoCAD. The transitions at the marked node points are connected to each other.

As you can see in the screenshot above, this is not the case in Rhino.

3- When I copy this linetype created in Rhino to AutoCAD, it loses its linetype properties.

4- Are there any other objects you would like to support besides curves and texts? (The first thing that comes to mind is hatches.)

I see; it looks like ACAD stops drawing shapes at the ends if the shape doesn’t completely fit without running off the end of the curve. I’ve added this to the bug list at

Yes, we want to try and support transferring this information back and forth with ACAD

I was thinking about hatches as well. Things do get pretty complicated if we wanted to support hatches will fills other than solid and I didn’t see any support for this in ACAD. Is there a certain type of shape that you want to make that would involve hatches?

Just wondering how these curves will look like if “WTR” is replaced with “NO BUGS” :smiley:

What about applying these shapes in 3d curves that are not flat? Will there be a control on the angle of rotation, twist angle or total revolutions from start to end?

12

Currently the shapes align with the view’s CPlane

Just solid hatch will be enough. I have not seen any other use case.

14

@stevebaer apart from already mentioned solid hatches (arrows!) and specifying an orientation:

Can the command behave like Flow? Speciying a base_pattern on a base_line and flowing the length of the base_line to the corresponding length on the target curve. This would be an welcome improvement.

I am aware, that the break-line example does not have the horizontal lines and the bbox - gap is chosen.

Hi hesro -

I’ve put that on the list as RH-88905 Linetype: Curve is Drawn where Shape Is

Hi Dan -

I’ve put that feature request on the list as RH-88906 Linetype: Deformable Shape

@wim

Thanks. Should not be too hard from a technical POV. Following example has two options.

  • Flow for shapes that can be deformed.
  • Orient for geometries that are more discrete, like hatched arrows

Very nice. I would rather like to have better surface handling then new line types.

There are several developers working on Rhino; each with their own areas of expertise. There are developers working on surface handling tools and there are developers working on new linetype features.

Nice to hear

linetype scale will work on this right?
