creation corners of sform

[Trial4life]

Hello everyone,
I would need to create some sform angles on a piece, or tilt the selected face of some degree than the one below. is there a simple and versatile way to do it, or should I be adding the necessary solid portion manually? I tried with the "draft" function in the "solids" section, but it gives me an error ("face/face checks fail"), probably due to the complexity of the solid (I imagine because it does not find a unique axis around which to rotate the surface). In fact, I tried the same function on a parallelepipedo, and I got the desired effect without problems. How could I do it for my piece?

I would try to create the sform before I added the semisphere.

so much to begin with you have more than one face and therefore you should specify which, if you mean all then what you want to get is not a sform as in the lower part you also have curved faces.

If instead the lower part you mentioned is that in the image shown above and therefore the plan (and it is also logical that it is this, because to make the deform on the opposite side does not make sense), you will have to set a corner for which no face is entirely consumed. the reference plan to be selected is not the one you highlight but the perpendicular one. (consider that at the point where the reference plane intersects the face to be tilted there are no changes before and after there is the inclination of the face. )

I would try to create the sform before I added the semisphere.

the problem is that I find myself with a single solid, so I can't remove the semisphere.. .

Hi.

Yes, the reference plan is what you said, I was wrong. the problem is that I still place it as a reference plan, (plan z-x to mean), and then select the face to be grounded (the one with the holes), but it always gives me that mistake.. .

Hello trial4life
I do not use if
same situation also in other sw
Maybe they are the holes that prevent the sform
if you delete them first or get them the sform should succeed
And then I'll do it
p.s.
if you need it all to make a matrix of a mold
you should ask if the deform goes to increase the size or decrease
always respect the plan
in general by international convention the forms unless otherwise indicated
are increasing
Thank you very much

in fact it was another doubt that I had... I should add material, instead with that function goes to get rid of.

However I also tried to eliminate the holes, but the problem persists. I am almost certain that the problem is caused by the curved surface of the spoon. I just don't have to add material manually, do I?

(sient to me)
this and my prob. in everyday life for several decades almost existential
add the material you need to do first
p.s.
What kind of mold is it?? ? ? ? ?
Thank you very much

the sforms are always to increase the quota if there are no different indications
is an unwritten but conventional and tacit rule

This is a ground mold from foundry for a university project.

However the first thing that comes to mind is to do an extrusion with the same profile of the face, (I know the sform angle, I can know how much I have to extrude), and then use the draft command. But then how do I fill the small space that is created between the sform and the spoon? the face that becomes tilted should prolong horizontally until touching the spoon, I do not know if I explained. . .

Sorry I don't use this sw
comungue
you have to make a model for foundry to which you have to add the metallostatic retreat
1% cast iron -1.8% stainless steel -2% and so on
maybe made of pine wood or hardwood plywood in beech or birch
Could you attach a series of jpeg to display your mathematical model in multiple pos? ? ?
Perhaps you need anime speakers with relative soul courses you could find other difficulties

In fact it had opted to make the holes later, for removal of truciole (as for the excavation in the terminal part of the spoon), then the model would be full, and there would be no need of the souls.

Anyway thank you very much for the advice!

all depends on the size of the shovel
for medium and large dimensions the speech changes and a lot
however we wait for some user or moderator of the sw you use
How to do
Thank you very much

Anyway I'm trying to do the deform by adding material manually. the problem, as I mentioned, is that a space between spoon and sform has been created. how can I do to fill it quickly?

to add material, as a reference plan, go to select a plane parallel to the basic and tangent plane at the top of the piece.

I don't think it's the holes that are blocking, if you want to try anyway you can "suppress" if you're in order or "stack" if you're syncing the holes.

If the model is done well, you should not have problems in adding a 1 - 1,5° sform.
if the project you are leading provides a drawing of the crude and one for the finished, it is better to review your files.
I and many others, in working environments, proceed as follows:
- raw part for foundry
- finished part (with part copy) and processing.
Specifically:
- on the raw part with sketches draw interassis, main coupling faces and guidelines of the finished piece, then proceed in drawing the model in 3d complete with overmetal. the sforms apply and then the fittings.
Usually the sforms are not a problem while the fittings are put logically and not all make it.
(advanced in an ordered environment (not synchronous) in key points are added copies of surfaces that can be easily recalled on the draft for quotation, for example simplified views without fittings for quotation or part of the finished.
- on a new part you prepare the finished piece worked, first you insert a copy of the part, of the crude, and then you remove the material as the machine tools would.

there are other methods but require a deep knowledge of the program.
if a sform fails, try to decrease the angle, for example 0.2 and then grow to see what is the face that 'disappears' to the growth of the sform: That face is the cause of your problem. (I laughed in other words what they answered in the first post)

the main problem was that I was working with a single solid... I tried a moment to remake the piece with protrusions, lofts, etc, and in fact now the command of the deform does not give errors. However, I have some difficulty recreating the shovel. In particular, I can't remove the inside protrusion part of the spoon. I tried to cut the upper flat surface in correspondence of the spoon, so as to remove the faces of the parallelepiped that intersect the inner part of the spoon, but cannot erase them. How can I do that?

then I would have another question: you said that usually in the working environment you draw first the finished piece and then add overmetals, sforms and fittings; why then prepare the finished piece worked on a new file part by removing the material how would machine tools do? Wouldn't just remove the added changes before getting the crude, so you already have the finished piece?

thank you again for all precious advice you are giving me!

Hi.
Everything depends on how the U.T. is organized.
typically if you have a piece all worked drawings the "finished" and then add the angles of overmetal sheeting and beams
usually these info gives the foundry to the modeler according to the requirements of forming and casting

the second hypothesis applies when you have a raw piece (except where worked)
then draw the crude and then remove the areas subject to processing
for your size if the cast is steel you have to add 8-10-12 mm of overmetal more sform
around there are a myriad of rules that indicate different things
but serve commercials after fusion to contest the fuse and save a little bit of euri
thank you very much

Excuse me again, maybe I'm also going offtopic now, but I miss very little and I will have solved everything! the corners of deform can perfectly on the reconstructed blade; the problem is that I still can't remove the part of bar that intersects the spoon (in the figure of the previous post). How could I do that?

Thanks again.

use the command "elimina face"

 

[Trial4life]

I tried, but it was trouble.
I finally solved with a dig in "loft" mode.
