Got a question about CAD, ask in this thread and im sure someone in the know will anwser.

heres my first question, how do i raise the dimensions so when i look from top view i can actually see the lines. as currently they go under the object

No idea on that one mate, I don;t use AutoCAD for 3D, Solidworks gets that job.

Don't use AutoCAD so don't know the answer, but you may need to set the properties of the solid body to show hidden lines?

Any UG/NX questions let me know...

is solid works similar to cad as in how you draw thigns etc?
are solidworks and cad made by the same people?

CAD is the generic name for all Computer Aided Design software. AutoCAD often gets called 'CAD' in the same way that vacuum cleaners are called 'Hoovers'. All 3D CAD software operate in a slightly different way but in essence they allow you to build up models by extruding and revolving sketch profiles. Some are more complex than others (e.g. surfacing). AutoCAD started out as a 2D package, and has extended to 3D over the years. I find it more clumsy to use than the likes of Solidworks / NX for that reason.

ok next question, saving a autocad drawing as a pdf file, is the only way to have pdf writer installed?

This is pretty much spot on. Most of the work I do is 2D based so I can help much with 3D stuff.

Yeah, we use CutePDF at work. Think it might be free. It's not really saving it, you plot/print it to PDF

You click print, then one of your printers is "CutePDF" it then prints as a PDF file.

If you want me to explain how to use the paper space, how to scale what you've drawn in there etc, I can?

Idea and half this thread! I've been wary about signing up to engitips or whatever it's called since I don't wanna be a noob lol.

Ive been having a problem with sweeping a shape along a curve then subtracting the resulting extrusion from another part, if that makeshift sense to anyone can you give me a hand lol? It's ugnx6. I keep getting something along the lines of 'target is completely outside tool body' but they intersect :s

knuckles, I use NX as part of my job. If you want to send over your file I can take a look for you?

got a bit of a cad issue which started last night.

when i add a dimensions (highlighted red) the text and arrows are coming out mega small so you cant read them. also when i go to insert and insert a block again (highlighted red) coming out mega small.

why and how did i do this and how do i stop this?

Right...

Right click up the top on any toolbar, it'll open a drop down menu, in this menu select "dimensions"

This will open a dimensions toolbar. In this tool bar there's an icon that's to change the "dimstyle"

Make a new dim style (from a copy of standard) go into that style and change the text and arrow size.

As for your blocks, they're not small, they're the size they are.

If you find a reference point, you can scale them.....

i.e say you have a side you know is suppose to be 5mm long, and it's 1mm long, you know the whole thing is 5x too small....

With that in mind, double click the block and open it (so you can edit). Then select the whole thing and type "scale" now, select a base point to scale from (bottom corner or middle or whatever suits you) then type "5".

This will then take it to the "correct" size.

Sounds like a bit of tom foolery has gone on with the blocks though.. need more explanation.

something is just not right.

everything was fine the other day, but not now.

if i open a drawing and check the dimensions they are spot on, if i insert that item as a block it comes out tiny. when i check the dimensions they are completely wrong

indeed just worked that one out.

seems its measuring in inches not MM

so when i type in 20 its doing inches not mm

how do i alter that (yes im new to cad)
 
There will be a units option in the tools menu.

Then you'll either need to start again or get busy with a calculator to work out how to scale it down to the right dimension.
 
When drawing in 3D view... my straight lines are vertical however when i draw a circle/arc - it is drawing it horiz, any idea? Pissing me off.

very strange when i go into the tools the unit options are MM

but when im inserting a block they are being put in as inches

You may want to have a serious look at Solidworks, especially if you're venturing into 3D. It's an absolute doddle to use, and that's compared to anything not just conventional command-based packages like AutoCAD, and still extremely powerful. If you're serious I do recall Solidworks 2013 will be 64bit only so make sure your hardware is up to it (though a 64bit OS pales into insignificance given the cost of CAD software!)

Student version is free but I don't think you're a student :p Not sure if they offer trials. Short story is convince your employer to invest in it - afterall it's fully fledged industry standard 3D world-leading CAD so it's still hilariously expensive (IIRC for freelance use it's circa £2.5k for premium version + £4k for CFD + £2k tech support)

Andy... have you considered google sketchup??

It's about 5,000x more simple to achieve what you want I think?

As for the dimensions not showing, you've got them frozen off in certain viewports on layout two.

What do you want showing and where?

sadly im a one man band trying to start a business in designing and building lasers. i dont have two beans to rub together so splashing out on solid works just isnt going to happen. im going to have to stick with my free copy of autocad for the moment.

now i know what im doing in CAD i find it pretty easy its just these stupid little things that get me. there are so many options in silly places that dont make sense.

yep i see what you mean in layer manager they are turned off. sorted now many thanks

does anyone know how to fix a UG problem?

every now and then it'll throw a hissy fit and wont let me put any more components in an assembly. it'll open the assembly list, let me move the part around but wont apply constraints. it wont even highlight the parts. its pissing me right off! lol
 
Still cant get my circles to draw verticle - can't seem to work this UCS stuff :/ all i wanna draw is 1 shape, copy it 4 times - draw a block for the road and render it :(
