Something is afoot with your drawing, as 0.4xp should be 1.2500? I can't see what it is though!

thought it was just me, but I'm struggling.

ive used unitless

??? hope so

I'm on my phone so I can't check side views but make sure everything's at the same height .

looks flat, is there a command you can use to set everything at zero?

Archtronics · Dec 7, 2016

Type Flatten.

I find this can lock up my pc so usually I manually select all, go to properties and change the Z value to 0.

Also check your fuzz distance in the pedit command.

nope flatten didn't work

(flatten worked, pedit afterwards didn't)

Had a look at this on the pc, its because you've drawn them as closed polylines.

If you select the polylines (straights), go to properties, under misc, you should see closed (yes) change this back to No.
Then you should be able to join them all up. :smile:

ummm when I double click on a straight line to bring up properties I don't get that option - I am using cad 2006

Archtronics · Dec 8, 2016

Hmm, earliest I have is 2007 and it works ok in that.

Try right click properties?

nope still not there.

I get that option for a curve just not a straight line

gee I'm not sure whats going wrong tonight.

Ive done a drawing in 1:1 scale, ive setup up a new viewport and I'm not trying to scale the drawing to 1;100.

how do you do it again?

Click on the viewport itself, I.e the box shape, and then set the scale in the properties menu to 0.01

Thanks, it took me ages but you need to do zoom then #xp

I was missing the zoom command

Slight thread revival, does anyone in here do any AutoCAD freelance work?

Just something I've been thinking about doing as a little side earner, but don't really know where to start.

I did. It's dried right up. Shame as it was ok. I found it through friends so can't really help.

Plenty of Indian/Asia country's doing it so unless your willing to do it for peanuts there's not much out there.

Eddie. · Jun 21, 2017

Yeah I figured it would be undercut by anyone with a lower cost of living.

Just wondering, it's a shame as it's something I can do with my eyes shut these days.

In what industry?

In mechanical engineering, autocad is the devil.

If you can, pick up solidworks or Catia. Much more scope for work

Eddie. · Jun 22, 2017

I'm training to be a Civil Engineer, should be qualified next summer, so AutoCAD will take a back seat in my world.

However, during my training, and for a good part of my working life, I've used AutoCAD, starting with kitchen design, and now for producing the more basic deliverables in the CE industry. Civil3D will be more my gig, in fact it is already really, but AutoCAD will always be around, I think.

My thought process was that as I start doing less and less AutoCAD work at work, I could do some on the side, because when it's basic work, I do enjoy putting some music on, and cracking through some drawings.

So to answer your question: Civil Engineering, specifically Strategic Highways, but interior/kitchen design is also there too.

could someone tell me why I cant extrude my shape?
doing my head in now

Panda. · Aug 15, 2017

Does anyone know if there's a way to replicate a shape (circle) along a polyline at equal spaces?

Essentially i need to show a 10m long retaining wall (made out of timber posts) along a curve, wondered if there's a quite way... (maybe @Rob or @Eddie. ?)

Eddie. · Aug 15, 2017

Yeah, array.

Draw polyline. Place circle on said polyline. Run command "array". Select circle. Choose "path". Select said polyline.

The array will produce a context sensitive ribbon, where you can adjust the spacing.

Rob · Aug 15, 2017

Yep. He's quite right. Then you can explode the array to make them individual items if required.

I know there are some very talented CAD people on CS.

any can do a xmas tree like this? I want to use my laser cutter to see how it turns out on some acrylic?

hm works for me?

Andy_con · Dec 11, 2018

I need to draw the shape of these pedals, but am struggling.

anyone got any suggestions?

using the oval feature does not work, the shape is different

Pep · Dec 11, 2018

Best way would be to split the curve into several sections and then spline it.
If you can scan it in 1:1 scale email it to me and I'll do it and show you how on a DXF.

Knuckles · Dec 11, 2018

Two identical circles for the top and bottom rad and one larger one in the middle, connect them with a tangent arc?

Rob · Dec 11, 2018

For a mini?

I have one and am cad skilled... I feel this could work out!

didn't think of scanning it, good call. ive tried getting a camera lens centred before, taking a photo then trying to scale it so perfect size. but sadly it never comes out perfect.

I have a scanner, so will try that tonight.

I understand what your saying but not sure how I would get top and bottom circles the perfect size.

yes yes and yes...

just in the process of making my son a plane shelf and I thought I know I could machine a propeller on my cnc router. ive drawn a simple 2d one but thought a sweet 3d one would be good.

anyone ever drawn one and got a design they would share?

before anyone says why not buy one, I like making things. and im making a plane shelf, not buying one!!

Should be quite a few on grabcad available for free.
