I'm currently taking an CAD program and I'm having trouble drawing a few objects in isometric perspective. These objects must unfortunately be drawn in 2D. I've drawn the orthographic perspectives for each object based on the dimensioning given however I'm unsure how to proceed on certain portions of the drawing. This is all homework and I doubt using any customization is allowed.
The first image is a top view of a fixture. I'm having trouble with the central portion which I draw by first constructing the vertical arm then using the array command.
Is there some way to create an array of this object that respects the isoplane that I drew my isocircles in?
If not, I'm able to look at the original using the VPOINT from the 1,-1,1 point and get the perspective that I want. Is there a way to use the UCS and trace over the orthographic perspective then take that traced image back to the world X-Y plane? I've tried this before but once I get it back it simply looks like the orthographic perspective.
The following drawing I'm simply having trouble drawing one particular curve which the green arrow points to. The drawing is of two perpendicular intersecting cylinders one having a slightly smaller radius then the other and the curve in question represents the edge formed by the intersection. The research I've done indicates that it's an ellipse however I'm unsure how to draw it correctly and the one I put in is simply an estimate. How can I construct the correct curve? Even if I could change viewpoints I'm not sure I could find a way to trace this one.
How to draw 2D isometric images from orthographic projections in AutoCAD as it seems many of the sites I find are either trivial or focus on drawing by hand.
is it possible to change a 'flat' drawing into an isometric type of drawing? I currently have an end view of an item that I need to draw in isometric, but it's fairly detailed with curves etc and will take a long time to draw again from scratch in isometric...
I recently started drawing in cad, and i have a couple problems. At time now i am trying to learn more of isometric drawing and i have couple questions about drawing a particular figure:
21.jpg
So in there i don't know how to draw that "thing" witch i highlighted in red. I don't know at witch angle i should draw it's center(center length should be 50 cm). If I would know that, i could easily draw a isocircle above. So how do i find this "right" angle?
Second question would be about isofillets - i read here in forums that i should do them in isocircles, and i did that and i got good results - it looks very good, but the problem is, that in this drawing, it shows that those isocircles should have a defined radius - R6, R16 and etc, but if i do round corners with isocircles, i dont get that result(in R16 case radius is even way too big). So maybe there is a way to do them "right" and have them defined? I attached that drawing .
I don't know how to rotate the 3D image to exactly the isometric view (30 degree, in this case) I need. I'm using AutoCAD 2005. how exactly to draw curves right in isometric view without using 3D?
I am trying to draw a "u bolt" in an isometric drawing. I found one solution, that served the purpose of giving the customer the general idea of the stands we are trying to sell them, but I'd like to know if there is a way to draw it properly.
I have attached a pdf to show what I came up with. Pipe Stands.pdf The only way I could think to get it to work (look right) in isometric view was to draw to vertical lines, make an arc across them with the elipseisocircle, and then use the path array to fill the U shape with the isocircles. This keeps the tubular shape, and the number of circles resembles bolt threads.
My problem is that the u-bolt is only threaded on the ends, the arched part should be smooth. Since this u bolt is to clamp fiberglass pipe to the stand, those threads (in my drawing) could cause damage. In this instance, I just explained this in the email to the customer, but I'd like to find a way to draw it proper.
My boss said i could generate an isometric view of a drawing if i have the plan, elevation, and side views (makes sense enough). how do i go about doing this? is there an existing thread i can be forwarded to? (searching "isometric" didn't seem specifically useful.)
I am using Xara Extreme 4, and am trying to produce an isometric drawing as I have previously done in CAD software. I have found that the lines drawn do not exactly "snap" to the grid points and some inaccuracy is evident if the drawing is magnified.
I want to know what is the better angle for drawing isometric stuff , Searching came up with 30 or 26.565 . however , i find 26.565 easier to draw with the pencil tool and i think it looks better . But 30 is very simple to draw because Paint.net do it when pressing Shift with the line tool .
So both drawing is okay , but i want to see your opinions about which one looks more like a professional isometric style , Here is an image of two boxes:
I have a 3D model, only poly-lines, i would like to turn it into a 2D isometric drawing (model space). Something similar to flatshot would do the trick. (flatshot works only on surfaces and solids...)
Im new to CADTutor, and fairly new to AutoCAD. I used to use Plant 3D which has the ability to create PCF's and Isometric drawings, but Im now using MEP. for the most part, a better solution for our company, but now we cant create isomtric shop drawings. AutoCAD now has Isometric WS CLoud. how we can create a PCF file from an AutoCAD MEP 2013 drawing? its seems rediculous that it cant?
it seems like Isometric WS is real loser if you can only use with Plant 3D
I'm using AutoCAD 2012 LT. I'm drawing an isometric object at 30 degree and -30 (330) degree angles. How do I set my line to use this angle and switch between these angles? The current rotate function is killing me.
When I start an Iso drawing should I use the 3D Views under the View tab and set it to SW Isometric or should I use the Snap/Style/Isometric way? I like using the 3D views, but it doesnt set the drawing up the same. What is the accepted procedure.
I'm working on a project where I've modeled obstacles for an obstacle course on a military installation and I'm having some issues with isometric views and adding dimensions at various UCS orientations.
Basically, each obstacle has a plan view and an isometric to depict height of some of the material above ground level and below.
I've tried re-orienting the UCS to accomodate the dimensions and it works to a degree but there has to be an easier way.
When I select the points for my dimension, I'm prompted...
Specify dimension line location or [Mtext/Text/Angle/Horizontal/Vertical/Rotated]:
I need the dimensions to be vertical in the isometric. I've been messing with it and I was able to eventually get it right but is there an easier way?
Whenever the dimension is drawn in model space the dimenion ends up far from where it needs to be. I always have to relocate it and re-select where I want the dimension lines to be.
Also, is there some kind of add-on that might make 3D dimensions easier?
Also, I have a thin solid representing the ground level so that everything below ground level results in a hidden line (due to the visual style I'm using) in the isometric drawings.
This works out great but any dimensions below ground level end up hidden. I don't think there is any way around this though with the style I have in use.
I've gone with simple callouts specifying overall material heights to avoid these issues in the meantime.
trying to draw a hex nut in isometric...I've got the ellipse with the inside/outside dimensions but as far as placing the lines and connecting them to make the hexagon perimeter I keep coming up wrong..
I have been trying to plot as a PDF an isometric view from CAD. I am using CAP Studio for these 3D symbols and for some reason even though I have monchrome.ctb selected under Plot Style Table my PDF is printing in color, not all black.
my DWG is set to monochrome.ctb. Everything prints ok except my 2 isometric 3D viewports which prints in its real color (visual styles are conceptual). Why don't they print also in monochrome? I saw a couple of discussions on that problem but the "hidden" and "hidden 3D" options in shade option isn't working...I want them to stay the same, just print in monochrome with screening! I read about some option called "hidden legacy" but can't find that anywhere.
We have been putting dimensions on isometric views and the dimensions have been coming out fine. Now, however, we have an isometric and the dimension is about 400mm out and is not on the plane/face it should be.
