"plan" of construction for elements in 3d

[ragnol]

Sorry about the question, certainly stupidly banal.

in the program that I use for cad/cam 3d (specific for structures in wood and steel, then one makes us also a refrigerator, wanting ), if I want to create 3d elements that lie on a certain floor (oriented as from my needs), I create a "piano 3d", the screen view is oriented according to this plan, and all that I insert is obviously aligned to this plan. Then I change my plan and go do other stuff aligned in any other direction. . .

Is there something like this? you work this way, in 3d when things are not "at 90°"?

I attach an image so much to make an example: how would you reproduce, by macro steps, this network support, and in particular the two inclined and divergent reinforcements?

in autocad there is the uct: move the origin where you need (both as a quota and as a position and orientation).
However the thing is less "rigid" than parametric modelers (solidworks, freecad, tekla etc) with the advantages/disadvantages that this entails:
- you have the advantage of being able to create a cube without worrying about doing it with any ucs and then move it or rotate it by going to place it somewhere else.
- you have the disadvantage, if vice versa if more accustomed to the above-mentioned modelers, not to know to "the eye" where puts the cube you create... then you have to move it later.
are 2 different approaches.

we say that with autocad it is not worth moving the ukras to model.

the first sentence "you have the advantage..." is a little ambiguous.. .

you mean (in pennies) that in autocad in general I should draw the element "in case" and rotate it/place it later?

in autocad you can orientate the reference system as you like.
for example try using ucs 3 points (there are many options. directly select the reference system darts with the right button to see the options). then wanting you can use the flat command so that the view moves to the new local x-y plan (modifying the ucsfollow variable you can set it to do it automatically but honestly I don't like it).
in this way designs directly on the local work plan.

autocad also allows you to work directly on the faces of other elements already designed because the bird adapts dynamically (you can turn off wanting) according to the position of the cursor.
If you then activate any mode other than wireframe2d (top-left curve and flight modes) you can use a kind of 3d glyph that allows you to move or rotate objects compared to straights and planes in space.
there is also the align command that allows you to rotate, resize and move the various graphic objects.

It is convenient and practical to always have the viewcube active (usually on the top right) to pass between the various views.

thanks for the interventions!
@legs You gave me a lot of straights. I'm trying to talk a little off.

already that there are: in the "my" software I can turn on and off 3d elements to pleasure, in autocad if I want to hide/discover elements I have to use the layers as well as do with lines, texts, retini etc or there are specific tools?

 

[Cristallo]

typically we work as for the lines the nets etc (the moment they live with us quietly). There is a command to hide a single entity or group (_hideobjects), but you must then remember to turn them back on (unhide) and I think it does everything together not only for a single object.

smanetta bene con gli ucs, che hanno risvolta (also not documented) molto utili.

...if you need to shape a cube. it is better to use them

 

[ragnol]

thanks for the suggestions. . .

I personally use the ucs icon with the mouse, transporting it possibly on what I want both the point of origin (in case it helps) and orienting the axes according to the need. I believe that the too many windows dedicated to the ucts then eventually confuse those who are at first arms. grasping the icon and orienting it properly is all much easier.

I have prepared a quick little video to explain the method that I personally think is more intuitive and quick. when there is to be drawn it is good to predispose the xy axis and possibly the point of origin of theucs.

 

[ragnol]

Tomorrow or Monday I look at it for good. Thanks

how would you reproduce, by macro steps, this network support, and in particular the two inclined and divergent reinforcements?

I made a little video.
working with the ucts 3 points I would establish the new xy plan (at the minute 0:58) to draw the shape of one of the needles that diverge. after that I would copy it and rotate it,
to attribute the sections of these irons I used the axis uct z . in the example I wanted to give different sections to the irons, just to make understand the use of the ucts for axis z.
I used the splines for which the trajectory of the needles is a bit curved, but the concept is that.
Moreover autocad eventually had difficulty in displaying loft surfaces perhaps because of the scale I drew with, I had to use the orbit to display them.

in any way autocad offers good manageability of theucs. I personally find myself more in difficulty with 3ds max than with autocad regarding the management of ucs

You can do it if the design is simple. Otherwise, depending on the complexity of the design, if you have the need to move from one floor to another then it is advisable to save the ucs by giving each one a name.
For example, in the last video, at the minute 0:58 I set the plan (a new xy plan) with the 3-point ucts. I could have saved that bird by giving him a name, and then recall it in case I had to go back to drawing on that floor, avoiding doing every time the bird at 3 points.
once I drew the profile of that first divergent iron I copied it by turning it (with reference).
but I could have created another new xy plan by saving it by name (distinguishing it from the first created) and drawing the profile of the second divergent iron. If I had to go back to drawing on the first floor, I would have to call back the previously saved bird. everything depends on the complexity of the design.

set the xy plans (I call them so) with autocad is very simple. with the icon of theucs it is practically possible to set any plan with great ease. with the various menus, dedicated to the ucts, we often get confused, while that is very precious.

In the following example I designed 2 planar surfaces and rotated them each at home. I therefore established for each surface what the xy plan should be and I saved the two ucs by name (first and second). at that point it is simple to recall the plan on which you want to draw. I could have used the object uct, instead of using the ucts for 3 points. but it is right to see with what ease you can handle ucs with autocad
