AutoCad 2D :: Construct Sort Of Compound Curve?
Apr 22, 2009
How do I construct a sort of compound curve using Autocad?
What I got is a circle or arc of about R=6. A node or endpoint about 5-6 units away from the center. I want a curve of R=10 to create an arc to go through the endpoint, and be tangent to the arc too. I can visualize it, but cannot draft it.
Now, I realize that there are a few possible solutions, but only one applies. I tried using the 2P function on curves, but instead of being tangent to the curve it comes up at a right angle to it. I can draw a tangent solution within a couple of seconds, but a curve?

How to construct a table to lay out the "horizontal curve" on the ground?
The steps that follow the design of the horizontal alignment is to set up it on the ground. For this purpose a table that contains angles and distances is established to set up the curve on the ground. How this process is performed on the C3D.

How to sort curve table data by parcel and then curve length? Out here in Oregon, one of the standard ways of defining a curve table is to show the length of curve and have each curve in the parcel grouped together.
I have not figured out a way to do this in C3D. At one point, Sinc had started working on the issue for us, but I don't think he ever got anywhere with it (or at least it didn't get into his add on.

I am using Illustrator CS3 on a Mac 10.5.8.
I am trying to create a compound shape from a compound shape I have prepared.
The first part works okay. I can combine the hexagon-compound-shape I have created from multiple hexagon shapes.
I then want to cut away the edges on a part of the compound shape (using a box of 4 rectangles), which is supposed to give me a rectangle with only the lines from the compund-shape inside this rectangle (image 1).
But when I cut away the box around my hexagon-compound-shape (using the Pathfinder window), the hexagon-compound shape inside behaves strangely, with only some of the lines showing and other lines missing (image 2).
I would like the rectangles to simply just cut away the lines that the rectangles are covering, and leave behind the lines in my hexagon-compound-shape, as they appeared in image 1, and not having hexagon-compound-shape changing which lines appear and disappear.

I have a paper blueprint of a floor plan, where all units are expressed in mm. I need to transfer this to autocad, so I am wondering how to construct the plan in mm? (changing units, etc.)
The scale is in 1:100. Does that matter?

I am having trouble constructing the roof for a 3d model. I have attached drawings which should allow you to visualise the type of roof I am aiming to construct.
I have had a go at using the box function then using slice to get the solid into the right shape but then I am unable to slice it at an angle as shown by the red dotted line on my attachment.

I try to use the ACA .Net c# API to add a new construct to my project. Currently in 2013.
In the samples I've found one for basic Projetnavigator things, but adding a new construct isn't covered.

I'm starting to set up Sheets from our template but none of the construct is transfering except for dimension lines. The views are drug in from Project Navigator. Elevations are fine, but when the viewport window is made larger the construct isn't there. I've attached an example of what is supposed to be the floor plan.
I've edited the walls but that made no difference. They are set to start at 0". Is there anything I haven't checked? I'm supposed to go to contract with these drawings next week.

I need to drawing something similar to the attached image on either side of a "U" shaped rod.
The "U" shape is drawn using a sweep of a circle (the hatched section on the atatched image illustrates).
I just can't fathom how to draw the solid at the top oneiter side.
I've been trying to add a plane at an angle, then draw a circle & try to sweep that for each half of the "u", but after a few hours, total fail

I have tried in vain to construct a planetary gear train in Inventor 2011 & the spur gear generator hasn't work much since the results are far from good, I have problems getting all the gears to fit together. The Internal gear has a diametrical pitch of d=120mm & the smallest gear a diametrical pitch of d=20mm, the outcome should produce a 6:1 gear ratio. The 3 other gears only offer stabillity, but I still need to know how I get it all to fit together with my measurements?

how to construct a curved tube/pipe run?
I've created a 3d sketch with the run of the tube on it but when I click "Derived Route" although the full 3d sketch is highlighted bugger all happens. There's nothing in the "Included Geometry" folder.
Is it because of the material? I've set it to a "Tube With Bends" and set my default radius.

I cannot xref a construct into a view dwg using PN. I get error "Could not reference file <construct> in <view>. Same problem whether I use relative or full pathing. But I can manually attach the construct using the XREF command. So I know it is not a file/folder permissions problem. What's annoying is that I did get it to work with one construct but not another.
I am using ACA 2013 and I see that there is a service pack 2 update.

I have ran an analysis and SSA gave me Error 607 on the report. It says "Inlet A9 gutter capture curve is not a valid curve."
A couple things I did different from the video lectures...
I selected user define for the Tc to figure out Q. i computed those manually.
For the Inlets I have selected Maximum Capture Cutoff.
There are some inlets in this model I created that do not capture 100% of the flow so i created conveyance links to account for the bypass flow.Not sure why is not recognizing the Curve?

I have several different views xreffed into a single view, should'nt they all share the base construct? i.e. If I want to overlay the lighting plan, HVAC plan and my reflected ceiling plan- they should share the first floor construct. Instead each one brings in the same base construct and then when you overlay them, the walls interfere and you get wall errors.

I'm trying to replicate the way these circles are connected for use in a new design. At first I tried constructing this with the use of a white outline around the circles. But this isn't a solution, as the white pace around each linked circle obviously isn't a perfect circle itself.
The problem is achieving a perfectly aligned, flowing "s" curve. The connecting points that are giving me trouble are in the red circles.I can approximate the connection points, but this leaves a "kink" in what should be a perfectly flowing "s" curve. I thought smart guides/snap to point would br useful here, but to no avail.

I have several parts to get cut for one of our customers.
The provided the pdf I have attached, and I need to create and .ipt so we can cut it on our tube laser.
This is getting the better of me on how I would put my work planes in order to get the correct angles.
How to accomplish this?

Just downloaded 2012 educational version - Hate to admit it but out of all the stupid things I have not found yet is the darn Zoom/zoom previous button! From what I see though, this looks like a great version. Enough for me to get on with my training again!
Basically framing in a small cubicle in 2x4's - 6'x6'x6' - Here's what I am grieviously trying to do... (In the drawing, anyway.) The base is to remain 6'x6' - tapering in at a 15 degree angle toward the top of the box or cubicle. The base perimeter 2x4's will need to be "cross cut" in a compound miter as they will be on their edge to form the base box. As well, I need to "rip" the edges of the base 2x4's to a 15 degree as well. Then my "studs" will be cut at the same degree.
I tried this with the 2002 version, but seemed to be going to L.A. Via Omaha. Must be a better way with 2012!

I'm stuck on a few different emboss cases. The following examples are just dumbed-down models to learn from. If it matters - I'm actually embossing patterns on more complicated parts - not text on primitive shapes.
Case 1: Emboss across several surfaces. Please see attached file "Wrap Emboss 1". I can wrap to a face - but not all three faces on the solid that I want my "TEST TEST TEST" message to span across. My embossed text goes off into space - it doesn't wrap around the edge of the solid as desired.
Case 2: Emboss text (or some other arbitrary shape) onto a single (but compound) surface. Please see file "Compound Emboss 2". If the curvature of the part isn't significant - there are a few ways to fake/trick out the model to get a passable result. BUT - when the curvature of the surface is significant relative to size of the text/pattern to be embossed - I haven't yet found a solution that doesn't wildly distort the embossed feature. As the surface of the part is compound - I can't use the "Wrap to Face" option without an error. The resulting embossed feature is unacceptable.

I'm having problems getting Inventor to dimension using the current view option on an assembly. I ungrounded the assembly and constrained it to the angled work planes that I needed so I have to use the current view option, but when I try to dimension to the intersection of the angles, it won't give me a dimension.I'm using Inventor 2011.

In the attached part, I am trying to show a hole drilled at a compound angle. I have attached a pic of what the part is supposed to look like. I am having trouble laying out the plane on a compound angle. The hole should be centered on the width of the flat and drilled through. 15° angle one way and 20° another way.
The ipt file attached is really messy in attemps to acheive the compound angle.
I am using Autodesk Inventor 2013.
