    You might have a look at this video, but I'm not sure if it's what you're looking for.

     

    Thanks for the help. this would do what I want but I would also like to know how to use the Clone and Eraser tools.

    I do suspect that I missed something to do with the layers. I will go back and check.

  2. I am using AP for the first time, prviously I used Photoshop which was pretty easy to use.

    I'm trying to remove part of the image using either the Erase or the Clone tools'

    I've read the manual on each of these tools but it doesn't seem to actually tell you how to use them - it only tells you what they can do and how to adjust their parameters.

    In Photoshop you could use the Clone tool by using 'alt' to select the sample area and then click the part you didn't want.

    Does AP work in a similar manner? If so where can I find the instructions?

    Also as I use the various adjustments part of the image momentarily blurs - is this a bug?

    Sure, but there is no way I know of for an Affinity or any other app besides System Preferences > Mouse to change any of those settings, so there must be some other explanation for why your mouse's tracking (or scrolling?) speed suddenly changed on your Mac.

    That's a good point however someone suggested that if I was using a 'special' mouse it may have been something to do with my mouse and not AD. I'm using a wireless mouse that I bought from a supermarket - nothing special as far as I know it has the usual left and right buttons and a scroll wheel.

    Yes, there is something odd going on with that document…?
    If you Group all the objects that make up that bottom right object it fails to display a correct Group bounding box. It just shows one white corner control handle where the bottom right of the bounding box should be.
    Similarly if the objects in the top right of the document are Grouped the same thing happens.
    Attempting to copy either group will crash AD (Crash report attached).
    The three objects on the left of the document behave correctly and cause no crashes.

    Was this helpful in reporting the crash or is there something else I could do.

     

    BTW I copied the image to a new doc and then exported it as a jpeg. This worked and I was able to insert the jpeg into the email.

    Blender is free. Donation is requested but not required to download, install, and use the program as you wish.

    @jackamus You wrote, "This could be useful when drawing  a perspective grid where the lines can be used as guides for drawing. I would add that because the lines are equidistant apart it must not be confused a being some kind of drawing scale. I have spent many hours drawing a grid and then trying to find a way to create scaled divisions along an X, Y and Z axis.

    The grid divisions in Blender are scaled and can be changed as needed. 

    I know its free but I can't get past the Donation window to download it!

  6. I have attached a file that I created this afternoon to explain how I create a 2 point perspective grid. If anyone can let me know if there are any AD tools or features that would simplify or make easier I would be interested to know what they are?

    In a 2D application like Affinity, this can be an unsolvable approach because the Z axis is missing as a property specifically of vanishing point perspective. For this reason, you are forced to simulate this dimension with lines at varying angles, while each single subdivision guide and illustration line max require a different, unique angle.

    And this is also the reason why various hints to 3D / CAD apps were mentioned occasionally in your threads about snapping and technical / construction drawings. (for instance)

    I assumed that you would have to simulate a Z axis and that is possible using a 3 point perspective grid. I used Z axis instead of 3rd vanishing point. The clever bit is knowing how to create them!

    Hmmm... Interesting discussion but, but, just saying, seems like a lot of work to mimic 3D functionality in a 2D program. In Blender -  which is a free program - the initial screen upon startup is a perspective grid that can be zoomed, rotated and panned at any angle. Why not just take a screen shot and paste that into AD as a grid to draw on? I know, some like to do things in the way that they like to do things but sometimes it may be better to look at the goal rather than the road used to travel there.

    If I understand right, your 'actual' goal is to create a (snapping?) grid for a later drawing in a vanishing point perspective. Though you could easily create nearly any density of lines with Power Duplicate, as demonstrated above by @G13RL, I think it wouldn't work well because either the density of lines is too low (and thus is missing some guide lines for a later drawing) or too high (and thus snapping at too many lines).

    Instead, it may work to first draw with a different perspective (and using one of the built-in Affinity grids) and then, once you have completed the illustration, bend its parts as groups to the desired perspective using available tools such as APh's "Perspective Tool" or, for vectors, the "Warp" feature in AD v2.

    This video shows the possible problems = required grid complexity for drawing in a vanishing point perspective in AD v1 :

    This video demonstrates the use of the "Warp Live Filter" in AD v2:

    In case your goal is a correct / perfect drawing in a vanishing point perspective you might consider to use a CAD application that enables you to choose the perspective. This reminds me to your recent thread about Affinity snapping issues in a technical drawing / construction:

    Two or three only? … or additional, intermediate lines via Power Duplicate, as you requested earlier:

    My last video, and I assume also @Oufti's recipe, concern the creation of such intermediate lines. Also your attached AD file seems to show this task (while I do see the file's preview only in my lack of V2 ability.)

    ADpreviewKopie.thumb.jpg.3b70f2c035bcf69f3d629af6d8ad226a.jpg

    Note, you also can set a position, lengths and angle for a straight 2-node-curve via the Transform Panel, without the need to zoom in/out (which appears to be the part you want to avoid, correct?). If you set the anchor in the Transform Panel accordingly you can distinguish between start and and node of a line without the need to have this node only selected.

    The efficiency of the various options may also depend on your entire setup, including the final illustration you want to achieve. Any forum's comment can be more precise and matching if you upload a screenshot of such a scenery. (I know you attached an AD file / unfortunately I don't see its content in V1)

    I used 'snapping target' as any element that may get snapped, usually but not necessarily by another object. The snapping options listed in the "Snapping Manager" dialog and in the 5 "Snap" buttons in the Context Toolbar are 'snapping targets" in my understanding. (While a Transform Origin can't be used as a snapping target for other objects).

    I don't think I made myself very clear to start with.

    So I'll start again. It was when I discovered 'Power duplication'. I thought it might be used to draw multiple lines back to a single point i.e. a perspective vanishing point.

    Form all the various suggestions made this was not to be the case as I envisioned it. Now I know that a snapping target is not s 'special' feature but simply another way to call a snapping node.

    I'm content to continue in the way that currently use. Many thanks to all.

  9. Thanks for all your various suggestions and I have looked at them and find they are quite cumbersome and I don't think help me too much on the way that I am currently doing i.e. Zooming out to create distant vanishing points and creating two or 3 (for 3 point perspective) construction lines from each VP with their respective 'Transorm origins' and node snapped to their respective VPs then zoom back and use the other end node to move the construction line as I desire and draw my drawing line to match it.

    The only item I have picked-up on is what is a 'snapping target'? How do you use them?

    I assume "transfer" was just a typo, right? – And possibly my "common" was misleading? As described above, creating an intersection of two lines in different angles will define the wanted transform origin coordinate. Since it is the same coordinate for both I said "common" … while in fact the Affinity interface doesn't know this if more than 1 object is selected but treats them as group with its own Transform Origin coordinate. If you then select one object only its Transform Origin doesn't have the same position but starts at the object's center again.

     

    I admit, it may be complex to first detect this intersection coordinate ("common") + then use its h/v values to one single selected line which then gets used for Power Duplicate … That's why I said before it maybe easier to start from scratch with 1 line only.

    I do see what you are getting Thomaso.

    How about this workaround. its what I have been doing in the past. If the angle between the two original lines is very small thus the 'a common origin' (vanishing point)' for both of them may be a long way off to the right then I used to zoom out far enough to see the origin and snap the ends of each line to this point. I then move the 'Transform origin' for both these lines to coincide with their common snapped nodes. This will give me 2 lines that I use later.

    I then zoom back out again and using the Node tool select the end of one of the lines then copy and paste it and use it as a third line that goes off to the vanishing point. I usually make these lines red to distinguish them from my usual black drawing lines.

    When I do 2 or 3 point perspective I do the same thing with the other vanishing points. This allows me to draw lines with the correct VP convergence.

    So I can continue to do this like I have always done. Its just that I thought that I might be able to use Power duplication in some way to create many of there vanishing lines.
