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:



- Michael

"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,

re:

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!

- Michael

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! ;)

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:

Perfect !
And Fat Lines can be used for design purpose inside Moi It-self!
(here the curve is a 3D curve)


For Apply it (fat Lines) to dimensions just transform them (dimensions) in "object"
by the trick of Export / Import (dimensions ) in the in PDF format!

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

Chri

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
> on 2 points to create the dimension and a third point to place the result

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:



- Michael

Hi Chri, also another thing you can set up to help with placing a dim in the z direction is put this on a shortcut key (like on the z key):

script: /* Snap to z direction */ var pp = moi.ui.getActivePointPicker(); if ( pp && pp.basePt ) { pp.restrictToLinePtDir( pp.basePt, moi.vectorMath.createPoint(0,0,1), true ); }

Then when you are drawing the dim after you place the first point you can push the Z key and that will lock it to the z direction and you can pick your other point. It's the same as making a construction line and activating "Project next pt" but just with one key press.

- Michael

Ok not a problem just that was curious the "Front View Camera", "align view" (?) was working for other dimensions
and not for this specific inclined one
(and very special diagonal view in only certain "Front" views) ...not vital! :)

Tricky the "Z" block! But not sure to well use...
seems that blocked the drawing of the vertical dimensions along edges in the 3D View ?
not only the one in drawing but next...
Even restart the prog and not re-using the Z shortcut...
here my shortCut used one time so the only thing I made...
script: /* Snap to z direction */ var pp = moi.ui.getActivePointPicker(); if ( pp && pp.basePt ) { pp.restrictToLinePtDir( pp.basePt, moi.vectorMath.createPoint(0,0,1), true ); }

I can't make this anymore ??? Vertical dimensions are not drawn in the vertical way like following! ???



OK that's return!!!
I suppose i had pressed "From object" button by error because i had not this inside dashed frame!



So now the "Z" blocker is working well! :)



Else


Seems Details don't access to these length...

But found again! :) Show Points and move them to the extremities arrows! Excellent!


The Edit Frame erase all when moved Points arrive to the Arrows! :(

PS

Does it normal that the Helper Line / Project Next Point works only on a Snap Point
and not also along an edge/line under the mouse move "on" ?

Hi Pilou, yes that is normal. That's because there are situations where the whole screen can be filled with an "on" snap especially for "on surface". If the point projection tried to use "on" snaps to then project it would make it difficult to track along the line.

Something like this for example:
