Description

OSE Warehouse is now being started in FreeCAD.

A

B

I just started: sorry, okay, so I just sorry, I just started recording. So the concept is go into the sketcher module with them.

A

B

B

Is that under workbench, then.

A

A

B

A

To draw a row outline of your of your profile when you are in the polyline tool, if you press the M key, you switch between different modes and you have a useful mode, which is this arc mode. Yeah.

B

A

Then you can, just you see the time being precise.

B

Using them clear, switching between M key.

A

B

A

Have this I will select those two points.

A

The point button, which would like put two end points on one uh-huh.

B

A

Then have to rectify all this so I. Take, for example, two upper line oppress the horizontal button. I take a vertical line and press the vertical button who.

B

A

One applies the welcome button, then I can specify a tick. For example, one point on the top line and one pump in the bottom line and I put a vertical distance.

A

Let's say I'll do one who anything now I will put one hundred millimeters and I do the same here between two or zero points, I put for exam two hundred.

A

I have my big dimensions: I must make sure my arcs have the right radius.

A

For this isolated arc, I press this button.

A

Same forward, arcs.

B

Yep, how do you select Imperial mode instead of metric.

A

And one just one thing is absolute angle: here:.

A

A

Okay, now I have one per profile: yeah.

B

A

Have to make the inner one so I do the same. Basically,.

A

B

You click on a single point: mm-hmm.

A

I'm rectifying.

A

This tire, instead of specifying the distance I, will just specify the distance between the inner profile and outer profile, which will be more convenient.

A

Sometimes capture is a bit hard to okay. I will put five meters.

A

So that's gnarly done I just need to put the radius of those arcs actually no I need to. So that will be five now.

B

How do you know it's five I guess by.

A

Five five, the first one was how.

B

Are you doing from the same pony.

A

Now I have my perfect profile, then.

B

A

See that it has two main dimensions here that you can change. For example, he wants another one: that's not 200 millimeters by 100, but you want 200 by 200. You can just change this here and since the inner profile is linked to the outer one, everything updates automatically hurry.

B

A

We can close, you know our base profile in the part design work big. This.

A

Part too, which is not in the form of extrusion, so we select our sketch press the path tool and we would extrude dots by 2.

B

Meters, mm-hmm.

A

This is all parameter, so I can come back here and change the extrusion heads anytime, so you can create different one easily.

A

So now we need our hole, so I think the easiest way is to go in the pot. One bench use that cylinder tool.

A

Well is the same here.

A

Yes, really small, so it's naked! Thank you.

B

Cylinder tool and party business, which workbench is this part part design.

A

Okay, now I have a good cylinder that will become the hole so now I will rotate it and place it at the correct location. For that I can use simply the drafts tools which are in arc module as well.

A

Do one thing: first, is take it by the origin and place it. I will enable centerline snapping. I will place it right here now. My cylinder is aligned with the axis I will profile. If I put myself here.

A

I will rotate it.

A

That's degrees.

A

And at least I place it arbitrarily here, of course, it should be placed with more care.

B

A

For now it will do I'm sure it's centralized because I placed it on the center line before so. The space between between starts of the beam and the bowler wounds it's now, but it should be done with more more care. Yeah.

B

A

Then what I will do now is use this draft array to which, basically, you can see that it created three cylinders at very close distance, but I can configure it.

A

Basically, I want it in the z-axis, so I want 1, X 1 in Y and I would want them.

A

Interval Z, let's say every 200.

A

I will make it only 9, because last one will cut half of all. This is all you can adjust it later space between our stuff. Now we have our two objects. All ready to do is apart.

B

Which one workbench are you in and.

A

This was spots.

B

A

Basic tools like.

B

Yeah, if you open that objects.

A

In between you still have the inner parts so.

B

You know it for.

A

Example, let's say: change the diameter of the of the hole in instead of 50 millimeters. Let's make it 25 and you see that it updates very.

B

Nice, okay, now tell me, tell me how you copy one of these and rotated 90 degrees. So if you want to do the corner of a box.

B

The road type tool would be and where nobody keep the other one there.

A

Optics Lizzie, sorry I just.

B

Think of the old one and rotate this one yeah keep the old one. So we create the corner like.

A

A

Cannot understand anything, is you saying I'm.

B

Saying leave the old one: what how can you leave the old one, so you have two objects that that's only with an assembly module or where no, you can do that here, right without assembly module. If you want to cut copy. This make multiple.

A

Module that comes with free candy is really non non functioning. You shouldn't use it assembly, you should use the one, that's that you can download from github, which is assembly yeah.

B

Assembly so I have that uploaded. So this.

A

B

Have that, so how do you take that so an assembly? How do you take this, make a copy and rotate? So would you do that in assembly module, or can you just do this analysis.

A

B

Mean what's the easiest way to make a copy? This.

A

Copy, let's make a copy of this.

A

If I use, copy/paste I can make a complete new objects. Okay,.

B

A

And paste, but it has, it- has its own internals, so I can, for example, make one shorter.

B

A

Which is and then.

B

You can rotate and snap them to one another. Show me how you rotate and snap one so so just a copy to land here to rotate.

A

Yes and I used the grid to have 90 degrees, because it's it's easy with the grid. You just take one start position: that's noise! Until in this end position that's vertical and you had 90 degrees and so I often use the grid to do rotations, because you can snap at logical positions now.

B

Show me the grids worst 9 degrees, where's, the grid button, so.

A

It's convenient and now to attach these things.

A

Yeah, you can add plain tongue strings. Let's say if you select two surfaces and.

B

A

It you use them so.

B

To rotate it, you use the rotate, which is the second symbol.

A

You have to rotate it to place before moving and.

B

The rotation tool is where.

A

Draft Wagyu draft.

B

B

A

Yeah, basically, that's it mm-hmm.

B

So can you just show the rotation how they look, so you go back to the other module and just rotate.

A

This one don't lecture: my mouse appears that.

B

One, the blue one, the rotate blue, huh huh okay, that one yeah.

A

B

A

You select your selected object. You want first to place yourself in the view where you will have your full rotation angle. It will be easier, then you press the rotate tool. It will ask you for a base point a start angle and an end angle.

B

B

A

You can also give those angles: numeric you can type dangle. Okay,.

B

That's good. Okay! That's a basic tutorial on making.

A

A moment I would say, dot use sorry. So.

B

That's a basic tutorial for making tubes mm-hmm.

A

B

You wouldn't use what.

A

B

B

You said you would not do what.

A

A

Because, basically, it still.

B

Under development but.

A

What about assembly.

A

B

How about assembly is that, okay or no.

B

Only that but assembly is that usable or else you're saying is not usable either.

B

B

A

The file is to pretty much development and yeah. There might be something that stops working at some point and or doesn't work anymore like it is working and that kind of stuff. So if you use that assembly to module, you should be aware that just change quickly because it seemed pretty early. Okay, I I, don't I, never use it at the moment. I only use manual, rotations and placement. Okay keep my stuff like that.

A

A

Yes, it's a matter of choice: lots of people already using that assembly module on the other four.

B

Right, but with a basic draft module, you can do things like rotate and put things next to one another.

A

B

In a basic draft module, you can do all the things pretty much that you need meaning rotations, moving things next to each other, copying and pasting, etc.

A

Yeah yeah, exactly and just you won't have the I mean, for example, what happens in the files I've been doing for the for the greenhouse and the objects won't move together like if you make one dimension bigger, you will have several pieces to move by hand after that and they won't move together.

A

That's the problem at the moment, but it doesn't prevent you from doing efficient work. Mm-Hmm.

B

Okay, that sounds.

A

Good, yes, let's say it's a Comfort Inn tab right.

B

So the other way, if we have the the Sketchup file, the only other way to make it effectively transfer to freecad, would be to what to export an SD. Our that's, also messed up or probably step would be the only one if I had to the other files and I could just export them only way. We could do it as in step.

A

B

A

It's so it already yeah.

B

A

Dae is meshes, so it's all only triangles.

A

This is not very practical. Once it's in freakin it's hard to do something with it. You know and well, when you have to those step files, it's already solid, it's the same kind of geometry that we can use this after that. If you want to export its export as mesh as well, but it's the highest highest possible level, and so it's much better quality. The curves just are still curves right.

B

Okay, yeah, okay, yeah! Thank you. So that sounds good, but so I'm gonna practice that what's the best tutorial on the assembly, module.

A

What do you mean sorry.

B

No, where would I find the best basic instructional on the assembly module? Oh.

A

I think there is.

A

Yeah, that's right.

A

And just gave you the link, that's where.

B

A

Discussion about assembly two happens and you will see people testing and asking how it works, and so at the moments that's all you will have. Okay.

B

A

Minutes we see on the github repo.

B

A

But I don't do you know there is no documentation yet the.

B

Get all assembly no, no I'm, sorry I'm, sorry, I meant not. Assembly I meant the draft, just a plain draft module. There are some good videos on that.

A

For the other modules, the draft modules yeah.

B

A

It being a good section or wiki if you could get winking, you go to the different modules.

B

Say so, free cat would web that worker /, wiki working so I go to working with workbenches and then the draft workbench yeah.

A

You have the list of work benches in each of.

B

A

Has full documentation yep.

B

A

Those tools, and if you take like fools it will.

B

A

Probably, how it works and all the options.

B

Mm-Hmm excellent.

A

Excellent okay, so yeah basically think that's page to tie into the workbench pages as kind of bookmarking yep.

B

A

Bras from there, okay.

B

Thank you very much so stop this recording and thank you very much.
