Help in precision

[Angelos58]

I ask to all friends with experience of Affinity Designer for iPad how drawing with precision.

 

for example I want to copy ten circles (same dimension) in different points of intersection. How can I make coincident the center of circle and the intersection point?

is there a way to offset an object at a precise distance?

could you suggest me link or document about geometric snap in Designer?

 

thank in advance. Every answer will be very appreciate.

If you draw a circle and duplicate it, you can use the controls in the Transform Studio to move the duplicate by a precise amount. The next duplicates will automatically be offset by the same amount.

Thank you Alfred, very useful.

 

other advices?

What else do you want to do?

For example: snap the center of a circle to a specific point, intersection

[Angelos58]

Or ... moving the center of a shape along a path, by distance or angle

That sounds like something we should be able to do when version 1.7 comes to the iPad.

I don’t think that’s currently possible, even in the desktop beta version.

As Alfred pointed out, don’t forget the possibilities presented by Power Duplicate and the transform studio for precision work as well.

I see and learn  and thank you Alfred and Paul.

 

with the lines and the shapes the “offset” positioning is less intuitive. If I would moving an inclinate line  and an horizontal line for the same distance would I calculate algebrically the different values?

[Paul Mudditt]

Certainly a bit of mathematics will help in creating a precision drawing and you can certainly move and scale in different planes, this is the Serif tutorial.

https://affinity.serif.com/en-us/tutorials/designer/ipad/video/272729523/

Horizontal distance = Line Length x cos(angle of incline)

Vertical distance = Line Length x sin(angle of incline)

 

[Angelos58]

Thank you.

 

is there a bug in precision? Watch, please, my attached video. Along the rotation the parts of inner circle change in relation.

You are right, but if all data are available inside the app, why don’t leave the calculations at app?

Are yes, if only software could read our minds, it’s not so easy for Serif to second guess what we are trying to achieve.

On a serious note as mentioned on another thread the numerical pop ups do include calculator functions so you can specify dimension or positional changes as relative using + and - or scaled proportionately using x and / to keep the calculations in the app as much as possible.

Example of calculator use with power duplicate.

Are you sure the circles were lined up, it looks like there might have been a vertical displacement which isn’t visible until you get to 90 degrees?

This is my example can you upload yours?

[Paul Mudditt]

I think your objects were misaligned, I can replicate your result and also correct it using the transform-alignment tools.

[Angelos58]

Paul, you are a magician.

 

thank you very very much.

 

about calculations, yes I know the Serif developers are not a think readers, but some values could be inserted into dashboards, length and angle of lines, offset values, like other graphics app do.

Very nice work ! There is a dedicated section for sharing your nice work, it’s not good to post in the questions area as it will overwork the staffers on their tea break.

Paul, I’m very sorry and thank you for the link.

I was reading my Help file (no really I was), and I noticed that there is a switch to adjust the rotation point. When you select an object, you tap ‘ Show Rotation Point' (the little crosshair symbol, top right of Context menu) and a cross hair appears in the centre of your object. You can drag this crosshair to set the rotation point outside the object. It produces the same result as drawing the invisible line to get a new rotation point. This is great apart from the fact that there appears to be a bug that causes the Transform Studios anchor point setting to override the Show Rotation Point Setting. At the moment we can't type the degree of rotation but you can move it manually. If they fix this it should operate like 'Centre, setting on Desktop. I think that’s what it’s called but not having a desktop version I can’ be sure. If you have it you will know what I am referring to.

Those pesky little icons ! Wish we had some pop up help on them using the question mark, nice one I’d better read the help again !
