Dashed-continuous-dashed polyline

So, is it possible to create one polyline that has combined dashed and continuous type of line in one polyline?

Posted

You can apply whatever linetype you choose to a polyline. After creating a polyline you can alter the linetype in the PROPERTIES dialog box.

If you type LTYPE in your commandline, it will open the linetype manager.

If you click on LOAD, you will see the library of available linetypes in the program.

You can create your own linetypes (search for it, there are explanations here somewhere I know) but I think the trouble you would run into is how long is the continous part and how long is the dashed part? Are they always the same?

So, I would create let's say 3 plines, and then I would like to edit one of them(let's say the middle one) to be dashed. (coz this line represent some kind of a road symbol)

 

something like this.

so, basically I want to edit just one segment of the line to be different line type but one line (when I press ctrl + 1 it would display the length of the line/pline)

And still keep the line a continous Polyline - gotcha.

 

No way I have heard of to do this unfortunatly - I hope to be proven wrong though!

I agree.

 

Anyway, thx for such speed replay.

It is possible with a bit of work, by using the fact that short lengths of dashed line are continuous, and disabling the linetype generation.

The picture shows the (apparently) continuous lines are actually short lengths (shown by the grips) but it is all one polyline.

Can u pls explain?

Look at Eldons image - every blue square is a vertex on the polyline, when you draw the line, you have to click at every one of the blue spots to acheive your result.

 

With all respect to Eldon, it doesn't look like a particular good solution though - scaleing in the Viewport for one thing will mess with the result to no end...

Nothing is easy when you want to do something tricky :shock:

deep. very deep. too deep on a monday.

But if you made the short lengths short enough, it could probably handle being scaled in viewports :D

boss: Oi! Can you make the whole polyline dashed?

me: uh yeah but..

boss: what? You're always saying that you only have Polylines so you can change the linestyle at the drop of a coin, now do it!

me: uh...

 

:P

That's the easy part. You just enable the linetype generation.

If you are still in difficulty, post a drawing with one such line in it, and I will try and give step by step advice.

Thx, but it won't be necessary we put that problem under rug. :)
