Question about the offset of converting features

Out of category
1

Hello @ all

I explain myself on a sketch 1 front plan

I created an ellipse 

I create a new plane (plane 1)  inclined at X ° and offset at a distance X

that I convert the entities in any direction of this ellipse

it does not remain via the origin

it deforms OK

but what is moving in this way there is a wolf for me

See attached image

thank you attached file SW 2017

the only way I found

is to make a surface extrusion to the plane

and convert the features

it seems to me a bit of a roundabout path anyway ;-(

It's normal that it doesn't work directly, everything works by direction of the original plane as you show in the vectors in green

No better in terms of simplicity

Drew the two planes N°1 and  N°2 from the plan on the right

A sketch with an ellipse (a square  or any shape is the same) on plane 1

I did a scan guided by a straight line (line on the front plane that is constrained in length by the two planes.

Then a circular sketch on the arrival plane and a removal of material to bring the material back to plane N°2

Then make a sketch with convert the entities.

Here if you want I'll make you a small word file with the different steps :-)

Hello guys,

It must surely be a bug. Did you do an SR at SolidWorks?

@ Zozo

for me it's not the original plan

It is the reception plan that is the problem

The fact is that the axis of plane 1 (plane of reception) which is inclined to it is perpendicular to its plane

 and passes through the point of origin of the front plane

yet it is the sketch of the front plane that I converted the entities/on the inclined plane

Logic is illogical for me

 @ AC Cobra

no I don't do SR at SW

@ Zozo

if you had read my previous answer

before your answer

gives me a walkthrough that for me is + simple

Surface extrusion to the plane

I think you should do an SR because for me it's not logical. When you project a sketch it should be projected perpendicular to itself.

For me this is the normal behavior of SW projection perpendicular to the new plane and therefore no simpler solution. (see image)

 @ sbadenis

in my internal logic ;-(

it should be the opposite :-(

since it is indeed the front plane

that I project (via convert entities)

on plan 1

maybe an option of choice would be wise

Convert features perpendicular to

- the origin (parent) or

- reception plan (child)

The projection should be made perpendicular to the plane where the sketch is located. It's more logical....

Hello

I agree with @sbadenis his .png is clear.

@gt22 look here, will it bring back memories:)

may the force be with you.

Hello

@gt22

 

If you still have the file, can you post it so that I can see how you made ""a surface extrusion to the plane"" because in my bad solution the extrusion can't stop on the plan which forces you to do an additional maneuver to get the same result as you (and that's not glop).

I've never done a surface before but I'll have to get started ;-)

@ OBI WAN

it is true that I did not remember + this communication thread ;-(

(and congratulations to @ cerdanya for the best answer) ;-(

but here the subject was a projected sketch

and to create a projected sketch

you need a support, either a sketch or a face, a plan doesn't work

and it is true that with a projected sketch it starts quite perpendicular to the origin

which is not the case for converting the

 which is perpendicular to the plane of reception ;-(

@ Zozo

yes here it is

Totally agree with sbadenis. When you create a new sketch on a plan, you always draw normal to that plane so if you put yourself in "normal to" view your ellipse is well projected as on your tests.

morality of the story ;-(

you have to go through a curve projected on a sketch 

and especially not by converting the entities

if we want the sketch to be perpendicular to the origin

See attached file sketch on sketch via projected sketch

and hide the reception sketch ;-)

@ ronathan

me personally when I converted

I did it in the normal position originally, that is to say seen from the front

but somehow

It always puts it perpendicular to the landing plane

I did X tries ;-)

Hi GT22,

Often doing this type of projection I have the same problem as you and I solve it in exactly the same way as you, by creating an extruded surface and recovering this curve at the intersection of the plane.

So you're not the only one in this case. :-)

For me, it should remain in the same logic as the projection of views, at least that's how I learned it in industrial design with projections.
