It is the first time I cite myself in the realization of a wheelbase using the surfaces.

I did the sketch on the three orthogonal planes and then made a loft between two of them using the third sketch as a guide curve... It's obviously not the right way because then I can't control the loft in the most critical part.
the result is that the wheel penetrates the surface. On the contrary, I would like the wheel to be at least 20mm away from the tyre.

Who can give me some advice?
I attach the particular file.

I think the approach with loft in this case is not correct. Do you have to take a wheelbarrow or a mudguard? according to my modest opinion, if you have to do a mudguard you will have to follow more or less well the shape of the wheel and then you should use a sweep that and then you will eventually extend or trim. if the aesthetic shape of a wheel is not particularly important, the dimensions of the elements around the wheel will determine the actual shape of the wheel are more important. in any case I do not know if it is convenient to try to do it with only one loft function that could be made complex by the need to use different driving curves.

It's a wheelbarrow! the photos should be clear.... .
for the moment I do not realize that the arms of the suspension and the ammortizatore penetrate because then it will be enough to make a cut.... .
what I want to understand is how to make the overall shape of the pasaruota: you say not to make the loft..... Unfortunately it is the first time I use the surfaces and therefore I do not know the alternatives well!

I think you'd better use software a little more specific than working with surfaces with a certain criterion...type unigraphics or catheia...

I'm so sorry... but it's not that I can buy caia just for a trash!
I'm just interested in circumscribing the...... I'm sure you can also do in solidworks.

 

[maxopus]

Of course you can do it in solidworks, from the boys we try to be serious, if for a wheelbarrow we have to take caia, for a car to whom we turn... at the center of the snowcake supercalcle?

Hi.

 

[Plus ENGINEERING]

considering that a sparrow is not so complicated, that sw is not very powerful on surface modeling, and considering above all that you have no experience with surfaces, why not try to shape it as solid?

 

[ilgioma]

Hello, Pika.
innazitutto what you want to do in sw you can do great without going to look for any other software.
I think the easiest thing to start is to work with simpler functions of the loft.
For example, you could extrude a semicircle from the outside of the tire to the inside of the mechanics and the wheel is already done.
Then depending on what you need to do you can make all the cuts you want, or insert other surfaces to create, for example, the dman of the shock absorber.
Obviously you will also need loft and sweep but for my experience it is always better to start from simple solutions, the complicated ones will come anyway.
I'm just sorry I couldn't help your wheel for the moment, otherwise I could post an example, but I have appointments that will keep busy for a while.
However I will follow the developments and as soon as possible I will try to give you a good hand where I can.

often you lose control of lofts because with a single sw-guide curve is forced to invent a lot of geometry; I am referring, however, to basic extrusions with loft. I do not know if for the surfaces the speech is similar, but sometimes I had to add more guidelines so that the loft actually did what I wanted....

There are those who modeled an audi r8 and a lamborghini with swx. He won't be in class, but a wheelbarrow is good.

I would not dare to do everything with a surface but make a solid or more surfaces.
if you need a particular shape go with + surfaces, for example the center and hips, detached and then go join them with a loft or better still with a surface with delimitation.

Of course you can. That's nothing. .

but do the starting and arrival sketches have to be different? otherwise solve very fast with a sweep of a profile along the path (that curve of 90° around the wheel).

if you dare with the loft you must give it more guidelines; What does he look like between profiles? fills it in the simplest way clearly.

and I quote everything about simplicity of execution.

I decided to follow the advice and not complicate my life, so I returned to the good old solids.... .
the result is satisfactory because it had to be a maximum encumbrance.
the use of surfaces was only for exercise, I thought I could do it on such a simple detail..... obviously I overestimated my skills: Perhaps it is better to first build the r8 following the tutorial to understand well how to treat surfaces and then move to something new.

as soon as I can post the solid.... .

....

you can safely sweep surface even without using solids.
