Full Version: V4 beta Oct-27-2020 available now

Hi Michael,

Here are some observations on v4 beta:

Copy as PDF :
When "Exporting as PDF", the objects sizes are preserved while when "Copying as PDF" they aren't.
edited :
(could be a problem with the way Affinity Photo and Affinity Designer read the PDF.
If I "Place" a previously exported PDF file into the Designer document and double
click it, it opens an "integrated window" and if I then "Paste" a copy PDF from MoI in it, the size is ok).

Copy and Export as PDF
Tick marks have the thickness of drawing lines instead of being the size of dimension lines.

Small display error when drawing solids (not specific to v4. It is really minor as the result is not affected) :
Draw a solid cube, lets say 10 x 10 x 10, starting at Origin, then, in the 3D view, start drawing another solid (or a rectangle) right "underneath" the first one, again starting at Origin. When you move the mouse to the back of the plane, it will display a negative value as long as the cursor is moved under the measurement of the bottom of the solid on top.
It doesn't cause any error if you click to fix the point. It is just indicating a minus sign in a positive area while moving the cursor.

Dimensions wish :
Would it be possible to add the Style (color) property to the Defaults as it already appears in Details?

Extrude command wish :
Not exiting the command after specifying extrusion length (would wait for right click by user).
It is similar to an earlier demand by Leonardo, but more specific to the use of options within the command.
Specially if Tapered is activated, if one enters the Extrusion Distance then press Tab, the cursor won't go to the Draft Angle text box.
If Tab is pressed, it would be possible to go back and forth Extrusion/Draft angle and only end the command on right click.

Add an Axis Show/Hide check box in the "Grid Snap" button wish :
This check box would be under the Show Grid checkbox.

Thanks again,

Michel

Hi Michel,

re:

> Will the "Ortho views only" hide, for example, the "Front" dimensions to appear as lines in the "Top" view ?
> I mean just like the "thickness" of "Images" placed in the "Front" view are invisible in "Top view".

I was thinking "Ortho views only" would have the same behavior as current ortho views. But there could be additional settings to limit it to just one ortho view. Maybe:

Show in: "All views", "Ortho views only", "3D view only", "Top view only", "Front view only", "Right view only".


> Would there be a "View" property of a Dimension that makes it belong to a view ?

Yes this would be a setting for a dimension to be displayed only in certain views so you could control generating a multi-view PDF file better.


> Would it be interesting to have that script included in the dimensions Pane ?

Yes that seems like it would be good.

They are selected when the command ends so you can position them using Transform > Move or dragging them. Maybe there could be an option to generate it inside a rectangle with a specific object name similar to how a title block template could work.

Hi Michel, thanks for the feedback.

I'm not able to repeat this with Adobe Illustrator, it appears to be a quirk in how Affinity handles pasting. It appears to be sensitive to the DPI setting in Affinity. Affinity seems to think the PDF file is 72 dpi (I don't think there is actually any kind of dpi setting for a whole page in PDF), and if your current Affinity document has a different dpi then it scales it.

Before you paste into Affinity, if you go to Document Setup > Dimensions and set DPI = 72 then it seems that it will paste it over without altering the size.

Pasting into a "Placed" PDF file works I think because the placed PDF file has DPI = 72.


re:

Tick marks have their own line thickness setting which is used. It's set in the Annotation properties > "Arrows" section, "Tick line width".

You can alter it for an individual object using Details... or set the default for a newly created one under Options > Dimensions.


> Small display error when drawing solids (not specific to v4. It is really minor as the result is not affected) :
> (width shows as negative)

It's actually not an error - it's due to the drawing using the faces of the cube as the current snap plane when you are placing points in the 3D view and have snapped points onto an object. If you turn off object snap or hold down Alt to temporarily turn off object snap for that pick so you don't have both points snapped onto the plane then it won't use the solid cube's plane as the current cplane orientation.

This is what allows for drawing things like rectangles directly onto the face of a box when you are picking points in the 3D view.


> Dimensions wish :
> Would it be possible to add the Style (color) property to the Defaults as it already appears in Details?

Hmmm, well currently when you draw any object it gets the "active style" applied to it, that is the one that has a ring around its color swatch in the Styles list in the Scene browser. You can set it by right clicking on a swatch. That is how the style assignment for new objects works for all object types including dimensions. But if I understand you correctly you want a way to set a default style for a dimension in the dimension preset instead of having it use the active style?


> Extrude command wish :

I don't know, this may be too big of a change. Having an extra step for all uses of Extrude is kind of like paying a "workflow tax" on all simple extrusions just to make that back and forth between Draft angle and distance work for the tapered case.


> Add an Axis Show/Hide check box in the "Grid Snap" button wish :

If you want to put this in now, you can do it by editing the file GridSnapMenu.htm inside the ui folder.

Add this below the <moi:CheckButton> for "Show Grid" on line #19 :

		<moi:CheckButton binding="value = moi.grid.showXYAxes"><moi:Text textid="Show grid axes checkbox"/></moi:CheckButton>

Hi Michael

Thanks for all these improvements

i m using Dim without changing "aux" plans

the next file is a animed gif

do you think that i use it like i should ?

Seems you don't use as you should! ;)
an hypothenuse diagonal is bigger than a side...etc
else the rest is tricky! ;)
Inclined vertical or horizontal selection is cool : only one point to move after for have same length of dimension!

---

In 3D View seems the rule is not to click on vertex but on edges for better position dimensions wanted !

and move points after if needing!

---

Hi Chri,

re:
> do you think that i use it like i should ?

I guess so - is there a particular result that you are not able to get?

One thing to note is that when you are drawing in the 3D view, the view direction plays a role in what plane will get used. It will be the one that is closest to facing you.

Here's an example - here I'm doing the same Dim Horizontal drawing command on the same points, but adjusting the view between uses to target different planes:

"Plane" is depending of the rotation of the 3D view ?

Trick of the inclined selection avoid to rotate the view but there is no equal length of side lines...
I suppose that is not visible if lines are same color than volume for print ?



Indeed (but i have not Printed for see if "artefact" are visible or not!

Hi Pilou,

Sorry I don't understand this part.

Hi Pilou,


> Trick of the inclined selection avoid to rotate the view

Rotating the view is how you control it, so it doesn't make sense to avoid rotating the view.



> "Plane" is depending of the rotation of the 3D view ?

Yes, it's the same as drawing other planar shapes. For example the plane that a circle will use is controlled in the same way and has been for a long time:



Hope this helps!

Yes I understand the Rotate plane! ;)

but

< it doesn't make sense to avoid rotating the view

it's losted time! :) I f you see video of Chris or mine we can draw any dimension in any positions
without rotate the 3D view's so the plane! ;)


> Trick of the inclined selection avoid to rotate the view but there is no equal length of side lines...

Parts of Dimension who are overlapped will be not visible if all are black for example! :)

PS There is no thickness for dimension lines ?

Hi Pilou,

re:
> PS There is no thickness for dimension lines ?

When you export a hidden-line drawing to PDF/AI format, you can set the thickness of dimension lines under "Line style options" > Annotations:

HI Michael

Is there a particular result that you are not able to get?

 

yes

In the following file, using the view direction, it is easy to measure the x and y values (126.45 and 299.64) but not the z value

Is there a way to lock dimension axis (x, y or z), then click
on 2 points to create the dimension and a third point to place the result

Not perfect but something like that ?

Edit Frame from Bottom + Snap

Hi Chri, for the z value one it would probably work best to do that in one of the elevation views rather than in the 3D view.

> Is there a way to lock dimension axis (x, y or z), then click

There is a way to do that, if you make a construction line you can then activate "Project next point" onto it:



- Michael

Ah damned I was very near the solution ! :)
Yours is very more elegant! (but i love also my Edit frame solution! :)
The helpers Lines are very powerful! ! The click move without release release must be a second nature! :)
And very cool use of the Project next point who was some mysterious is very enlighting here!

---

hI Michael

Excellent trick
the solution is to create a projection point before !

thanks

@ Michael : Your videos are not resized by the forum :)

Else last headache for be complete in 3D view!

Does it possible to draw a double arrow between A & B ?



I found but it's not direct!
Draw any dimension somewhere then Orient Line / Line Scaling: Stretch ! :)
(will be fine if numerical number will be front camera...if possible...

---

Hi Pilou,

re:
> @ Michael : Your videos are not resized by the forum :)

Yes, the forum only knows how to resize images, not videos.


re:
> Does it possible to draw a double arrow between A & B ?

Well the dims are planar objects so you would need to make a construction plane that had the line between A and B on it and then you could create a dim there.

The essential job of a dimension is to label the projected distance between things, not the 3D distance between things.

Trying to label 3D distances is dangerous because it becomes easy to misinterpret the measurement.

So when you see a drawing that has this for example:



it should be this distance that is being labeled:



and not this:
