How to create (guide)lines that meet atvanishing point out of the screen?

[pepr]

Hello to all,

I try to create the icon like this the correct way...



I did compose the image from the freely available SVG icon https://uxwing.com/box-icon/ The width of the stroke is not created by the line thickness (causing problems with buts and caps). All is drawn with no-width line as a complex shape like this:



The box uses two vanishing points. Because of that, putting two boxes together looks strange.

I would like to draw it from scratch. And I would like to learn how to work with vanishing points in Xara. My idea was to get the original cube and use the Guidelines layer to add lines that join in the two vanishing points. However, the vanishing point is quite far from the picture and it goes out of the page and even too up, out of the page stripe.

What is the correct approach?

Thanks and have a nice day,
Petr

P.S. I did Arrange -- Combine shapes -- Add shapes to put the two copies of the original together. Then I did remove the extra points that should not be there. I have to say, I should also search for the correct way to remove the extra points. Would that be the a good question on its own?

I'd put the vanishing points on the sheet where you need them (on the guideline layer), then draw the boxes small in the middle to the correct proportion, and the size them up as the last operation.

It's not the two vanishing points that makes them look strange, they are just not correct ... The angle between the boxes should increase not decrease.

Why not using the Isometric Grid?

I was thinking about that. Thanks for the confirmation.

Here I think we are on the same base. The problem is that the single box is drawn using two vanishing points. It is not correct to add the second only by copying with any offset. The reason is that after that there are actually four "vanishing" points. The related ones are not aligned. This is the reason for the strange angles.

This is rather nice comment, indeed! (Actually, I do not need the vanishing-point look for the icons.)

Thanks.

Depends whether you really want a perspective or an isometric. There's a big difference.

I know this. But for the constrction it can be easier. Then you can do every deformation you need.

This was a fun task. Here's my attempt. If anyone wants to know how I did it I'll be happy to do a tutorial.

@Egg Bramhill: This is nice -- also the shades of blue on the first picture. I do not know if the tutorial is not too time-consuming. Anyway, could you write the approach in bullets?
