AutoCad 3D :: How To Draw A Piece Of Duct
Feb 11, 2013
I wanted to draw a piece of duct....a transition piece to go from circular duct to rectangular duct, and make it so that the circular is offset from the rectangular.
I didn't need anything too pro so i started with a rectangle and a circle, then started drawing a few interconnecting lines. I tried a few 3D commands, but none of my usual seemed appropriate. What loft does?
quick search on yt: [URL].....
click - click - click and it's done! i reckon the whole shape could be done in under a dozen clicks!
gave SHELL a go with it and it's exactly what i was aiming for (never thinking i would get close). i've no idea why it is called 'loft' tho!

I was editing my largest project to date (I'm still well a novice) and once I needed to remove a middle portion I realized how in the heck can I slide the remainder entire timeline to fit the gap? I tried the slide tools, hand tool, and the track select tool. I know host to highlight the remainder of the timeline.

Any dynamic block or any sort of add on for running HVAC flex duct in a drawing in AutoCAD LT 2D? I am trying to come up with any easy way to show more detailed duct work beyond just a single line.

I am trying to add geometry programatically to a duct fitting. This is because the content builder is incapable of correctly building some types of fittings. I found some old code from an Autodesk University class that shows how to add geometry to a AEC object. I have modified it a little to be able to work with a duct fitting but it does not work. The code compiles fine and runs fine without any errors. The geometry is just not added.
[CommandMethod("ACAClassCode", "ExModelerModifyBody", CommandFlags.Modal)] public void ModifyBody() { Database db = HostApplicationServices.WorkingDatabase; Editor ed =

I am trying to place HVAC duct work in Revit 2014, and every time I draw the duct work I get a error message: A serious error has occurred. The current action hase been canceled. It is strongly recommended you save your work in a new file before continuing.
Is there a "BUG" in the systems side of Revit 2014, I have downloaded the Release 1 and the service pack 2 (which that is crap also).

I am trying to model simple translation piece from rectangular to circle (one quarter). There is angle between rectangular side and circle side. I am able to model it very simple, but I have found that Inventor make some errors with lofted flange. Usually this type of translation piece should have flat triangles on the ends and bended triangles in corner. Unfortunately for some combinations of width/depth/diameter Inventor does not keep this rule and add some bended triangle to end edge.
Enclosed is pdf file with picture how this part should look, what is the problem and finally the ipt file is enclosed too. The part is OK with parameter SizeY=250mm and less and is wrong for bigger SizeY (for example 600mm)

I'm new to autodesk. I cannot seem to figure out how to angle a piece of material after it has been extruded.
For example, If I create a shape ie. a 10mm square and extrude the shape to a length of say 100mm, and want to miter either end at 45 degrees so as I can join them to create a 90 degree angled piece....
How do I angle the end of the extruded piece?
I know it can be done with a simple chamfer but this is not ideal when dealing with more complicated shapes.
I am using autodesk 2012.

I have a piece that I'm trying to develop to add into an assembly. The piece I'm trying to create is a cast piece of steel that I'm trying to form to a radius. The piece basically starts out as a flat part and then is formed to a radius. I want to form it from flat to radius so that the contours will match the radius of the piece.

I am using AutoCAD 2010 3D and though I am reasonably comfortable with 2D, the 3D stuff is hurting this wee brain of mine. Here is my objective. I have drawn a 3D image of a piece of wood in the 3D model space. I want to profile the edges of the wood with a router design, in this case a Roman Ogee, (see drawing). I have drawn the Roman Ogee in 2D, copied and pasted it into 3D then extruded it. I moved the Roman Ogee router profile into the area at the edge of the board I want the profile to be but I just can't figure out how to get the router profile to run along all 4 edges of the board to look like the image above.

I have a rectangular piece of sheet metal and all I want to do is make the sheet curved with a radius of 113.75 in.
How do I go about this? Is there an easier way like making a 3d sketch and putting a sheet metal face on it?

I am wondering if there is a way to use a part of one piece located in an assembly to cutout a portion of another piece located in an assembly when both pieces occupy the same space?
The situation I'm in is that I've got an L bracket (piece 1) resting on top of a piece representing a concrete block (piece 2). The L bracket has metal studs attached that protrude into the concrete. Idealy I'd like the mass of concrete located in the same space as the studs removed so that when I generate cross sections everything adds up.

I am trying to draw a circle on an angled face on a valve I made, and am not too sure of the best way to do it.
Here is a front view showing the angle. I need to use the face at the top that is on a 22* angle or so

Here is a top view showing the 10 holes I need to make at the proper angle. The blue lines are showing where each of my holes will need to be with a fitting on it as well

I have a question about Radial dimensions... I am trying to add a piece of text (TYP.) to a Radial Dimension... When I add the text; it makes the text and dim line move further from the arrowhead (see image)
I want to be able to move the text on the dimension closer to the arrowhead without actually exploding it... my current solution is to separate the text (TYP.) from the dimension (see image)
Is there a variable or setting to shorten the length of the dim line on the dimension?

I'm just starting with ACAD 3d. I'm trying to draw a handle for a ball valve. The handle has a horizontal piece and an angled piece. In the attachment, you'll see that there's a gap where the two pieces meet. How can I close the gap so it looks like a seamless piece?

I am wanting a piece of info that I cannot seem to locate in the spur gear generator. I will post a picture when I have a chance, but what I am looking for is the 'W' figure (distance over 'x' number of teeth at the pitch line). What I have is a 19.xxx deg. helical gear so the best way to get this info is calculate it, but again, I dont see it in the inventor calculation.

Just installed service pack 2 on Civil 3d 2012...
I go to open a drawing; drawing opens fine and views fine for a second, but then everything changes to viewing Color 9.... I am able to select a line or a piece of text and change it to any color imaginable but it always stays color 9. Although I am able to create a line and have it the correct color, it is just everything that had been existing in the current drawing at the time...
I have tried shademode, which if I put it into a 3d wireframe views fine in modelspace... but it always is going back to the 2d wireframe visual style that is the problem...
I cannot seem to find any problems with the drawing... I have run audit and purge all, I open backed up files and autosaves, all doing the same thing... I even had someone else open the drawing with the same occurence...

How do I CG a traditional art piece on photoshop that i've made that has been inked and such while giving it depth and lighting without making it look unrealistic? I've tried to find this from sites and desided that maybe it would be better if i got a multi-help unit to help me get this through my thick skull here.

I have a ton of stock images with the backgrounds removed that I need made to look like a puzzle piece with a 3D feel and a slight shadow to make it look like it's floating above the canvas.
I also will need to make an indented outline of the image where the puzzle piece would fit. I've attached an example of what I'm looking to do (I don't need the wood background, I think I'd probably just use a solid color).

This is my model. Simple.
Now the only thing I want to do is to cut out this:
[URL]........
I used the Extrude tool just for visualization. The problem is, working with booleans apparently doesn't work for such objects, it works for freshly created clean polygons, but not for this one, when I try to use "Boolean difference" both objects disappear.
Extruding doesn't work because the faces are still there and I cannot delete them for whatever reason:
[URL].........
My cursor is pointing on the little face, but both are being highlighted. Making a hole through the the "Make a hole" function doesn't work because it only deletes faces as it seems.

Suddenly I'm having problems with the Arrange/combine/slice feature.
When I attempt to slice off a piece of an image, another straight cut occurs somewhere else on the image.
On the attached sample, I drew a wavy line like the one shown across the right arm of girl in the image and along with the expected slice was the vertical slice through the image. I backed up and started again, and the exact same vertical slice occurred.
This happens frequently, the unwanted slice is always straight , but sometimes horizontal, and sometimes angled. I'm using Wacom Cintiq tablet.
I'm having the same problem with my trial 7 version. I've been 'slicing' since Xara was a puppy.
