Arrowheads don't keep size in viewport captures

[Bogdan_Chipara]

ViewCaptureToFile should capture exactly what I see on the screen, instead the arrowheads becomes much bigger. Why? (this is with PrintDisplay=On)

that the line exceeds the arrowhead annoys me for years..

[mi.land]

Yep i find it annoyingly ugly as well. Seems a small change shorten the line by 1/2 arrowheadlength while not moving the arrowhead…

These arrow bugs seem like a small thing, but if fact, because of them I have to place all the arrows for the diagrams i’m making in indesign (Affinity Publisher actually). Which takes a lot more time than in Rhino and makes me use a software which i don’t really need for making diagrams.

Here is the reason, why Arrowhead are displayed “incorrectly”:

Rhino 8 dimensioning non-linear feature?

The problem with arrowheads currently is that they are “screen-space” objects (like Dots) that do not change size with zoom levels. They are unlike the actual dimension object arrowheads which have a dimension style-specified fixed size when displaying/printing. As far as I know a this has not yet been implemented for just adding an arrowhead to a curve.

same here. i don’t want to fire up Siemens NX everytime i want perfect arrows. or postprocess it in inkscape.

Yes, well… i understand what @Helvetosaur is saying.

But it’s just an arrowhead, not rocket science, I’m sure it can be improved somehow. It will save a lot of time for us.

To get proper scale, there is the workaround of using leaders, eg. with no text. It doesn’t solve the issue of arrows being plain ugly, though.

Besides fixing arrows, it would be great to get advanced linetypes in rhino9 for example like these:

There are plenty more advanced linetypes engineering professions use, it would be cool to be compatible with them. I guess arrows need to be implemented in a similar manner to the arrows, both are on my wishlist

Either way, I personally would prefer existing functionality being fixed (arrows) over adding less essential new features.

have a look at this thread @omichalek. this is basically your advanced linetypes for engineering wish.

Rhino WIP Feature: Shapes in linetypes

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. [image] 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 spac…

awesome, thank you!
