I understand how the current extrusion command works - You have a 2D polyline profile and you apply the extrusion command to that, getting your 3D shape.
However, I have a drawing full of different sized extrusions based on the same 2D polyline, and now I want to change that initial 2D polyline without having to manipulate each polyline separately. I thought it would be much better if the initial 2D polyline were referenced, allowing you to swap that inital 2D polyline with another 2D polyline. Is there a way - or a plugin - that is available to do this in AutoCAD?
FYI - the profiles are used in kitchen doors, and I want to be able to simply change the door profiles without resorting to re-extruding the whole lot.
The attached files are two sprockets. The original part has 30 teeth. I need 34 teeth.
The MODIFIED part has one of my attempts at making 34 teeth. I have tried the following with the same error dialog box (see below):
1. Edit Sketch_6 (associated with Extrusion1) by deleting all but one of the teeth lines (2 arcs and 2 lines that make up a tooth) and making a circular pattern of 34.
2. Same circular pattern, except this time I "Close the Loop" (right-click on one of the teeth line segments > Close Loop > click on all the segments until the loop is closed).
3. Same circular pattern, except this time change the resulting patterned lines into construction lines, trace these lines with arcs and lines of my own (not construction lines), and close the loop on my own lines.
When each of the 3 attempts failed, I tried deleting Extrusion1 and making a new Extrusion feature from Sketch_6. I cannot select what I want in Sketch_6 in order to make the teeth.
I'm at the point where I'm just going to take the dimensions from the circular pattern sketch of 34 teeth, delete Extrusion1 and Sketch_6, and make my own sketch and extrusion.
For the future, I really would like to know - why is it so difficult to alter features like this? Yes, I understand that Sketch_6 is not fully constrained, and on top of this I am not privy to how it was generated in the first place (this is a part file from a vendor). But it does not strike me as something overly complicated for the Extrusion feature to recognize a change in its associated sketch. This is not the first time I have encountered something like this.
I originally did an existing surface that I was not really satisfied with. Then did an existing and proposed profile using the LandXML import/export option for getting the information from one file to another. I have since redone the existing surface to something I am more satisfied with, and set up data shortcuts, but I cannot figure out how to update the existing portion of my profile.
Essentially, I want to "unload" the previous surface information from LandXML and redirect the profile to the data shortcut information so the existing portion of the profile can be updated... preferably without disturbing the proposed portion of the profile.
There is a dialog box that lists information about the profile, but it does not want to let me modify or change anything.
attached are 3 files that demostrate what is happening when I select a profile to loft and the rails of the Surface and how it changes the profile and how I can get a straight back edge not bowed in like it did to the front
We had to migrate from one domain to annother on our network. This meant that each user had to create a new profile.
Before we migrated I tried to back up the user data from the old user but once I am up an running agian all the AutoCad settings are no longer included. I understand you can export those while you are logged in and can see the macros etc. can you simply move the files that store that information (I can still access all the files from that user I just can't login as that user anymore)
Every time I try to change my profile image, I get an error message saying.
"The file you uploaded is too large.
This section will allow you to specify a photo to be used in your profile which is viewable by other board members. Photos must be no bigger than 150 pixels by 150 pixels."
The problem is the image is already smaller than 150x150px I've checked multiple times.
I'm shooting with a Nikon D3s and always had the problem that the imported photos went a few stops darker when they were imported in Lightroom. I figured out that I get better results when I change the camera profile from Adobe Standard to Camera Neutral (which probably equals my setting on my camera)
So how can change this setting for the rest of my already imported stock and how can make this the default setting for my future photo imports?
I'm building a test track to use on a driving simulator.I'm trying to apply banking to the corners. The track's path is a loft with it's path defined as a line, and the loft shape is a rectangle to represent the cross section of the track. I'm trying to apply banking to the corner by using a different shape part way along the loft... however, the result is that the track twists the wrong way so that the top of the track becomes the side and vice versa.
I'm having trouble when I move photos from lightroom to photoshop. When I change the color profile from ProPhoto RGB to Adobe RGB 1998 the color becomes highly unsaturated. Avoiding changing the profile is not an option. Is there anything I can do to prevent this from happening?
C3D 2013. We have profile line labels, some of which get manually edited (for example, change the "<[Tangent grade(FP|P2|RN|AP|GC|UN|SD|OF)]>" to a static number such as 0.29%).
However, if you CTRL+Click and select one of these labels and change the style of that one label, then the manual edits are lost and the label reverts back to the default string.
I'm trying to understand extrusion to 3D solids better. This started when I drew a joined, closed 3dpolyline and found it wouldn't extrude (the shape titled 3D POLYLINES 4 sides joined, in the attached DWG), even though everything lies in the same plane (z=0). It gives the error "segment chord not perpendicular to normal". A chord is part of a circle, and there are no circles in the .dwg, so I don't understand the error. If you join only 2 or 0 sides, then at least 2D extrusion to a surface is allowed, but not if all 4 sides are joined, i.e. one 3D polyline.
If I draw regular polylines overtop the 3D polylines, then join and close them, it extrudes into a solid. This suggests that 3D polylines can't be extruded into a solid when regular polylines can, yet if I draw some scratch 3D polyline geometry that is joined and closed, these 3D polylines will join. It's as if I've found some secret shape that AutoCAD refuses to allow extrusion on.
I wanted to add an extrusion to an asembly. I was able to highlight the required geometry and create the feature, but is not showing up. In the browser, there's a red "up arrow" beside it. Why is it not showing?
I have a multibodied part (roughly 700 parts) and I need to do a cut extrusion. The problem is that when I'm cutting through a hundred or more solids I might miss one if it's close to the edge. I though, no problem I'll just go back to the extrusion command and add those solids I missed. Problem, the program only lets me select one solid and undoes all I had previously.
am used to using autocad 2010, i am using 2013 now and i cant figure out how negative extrude so to speak, if i extrude too far, how do i remove the end of the extrusion?
I cut a curved profile using extrusion and mirrored it about the original plane. But It doesn't cut thoroughly ? there is still a surface of the rarer side of the part ?
the original extrude cut was "Through All".When do the same cut gving a distance...it mirrors perfectly..
I would like to create an effect similar to punching/stamping something in wet sand. Picture this... you have a punch/stamp and it says "Hello". You punch it into the wet sand at the beach and it keeps the form of the punch/stamp. You can see the interior angles/shapes, but not the exterior as it is part of the rest of the beach I want to be able to create that effect in a graphic/drawing.
If you want to look at it another way:
Say you have a glass. You also have a hole in the table to hold the glass. Once in the hole, you see only the very top of it and the inside of the glass... but that which is below the table is not seen. If looked at from above, you can see the interior that is below the table, but not the exterior.
I would like to cut a section through an extrusion. Attached find a section view of my extrusion cut at 90%%d. My deal is I want to be able to specify the angle. It could be anything, and it could be a compound miter (using in saw-speak, because my drawings go to saw operators), that is, angles in two directions. But, let's keep it simple - how to cut a section parallel with the Y axis in the attached drawing?
Right now I am warping something in due to the complexity of the profile. But for accuracy sake it is obvious why I'd like something better. I'd like my operators to have confidence in what they see.
I could do this easily in Inventor. Or even oin Civil 3D, working around it (using Autodesk-speak). But, I have neither. Is this a UCS thing? I trained myself to never touch the UCS long ago, because I am a surveyor by trade, and surveyors pull coordinates from AutoCAD (or one of its children) to stake points on the ground with, and a surveyor ends up working at McD's if she/he goes outside with coords pulled from a made-up UCS. So I don't know the first thing about manipulating the UCS, despite daily use of the products since release 12.
I looked at Sections in the 3D modeling workspace palettes, but nothing really jumped out at me for being able to rotate or cut sections where I want them to be. They all seem to snap to existing planes of the extruded solid. Big deal - I can do that intuitively just by looking at the part.
The MASSPROP command tells me this thing has an area of 0.785 square meter. I can run MASSPROP on it and get some information but how would one determine how much weight for aluminum would be involved with this and how could I calculate? I want to know the weight of extrusion in kg/m. and also show how?al ex.dwg
I am working on detailing an assembly that requires two parts to be bolted together and then have a hole bored through both parts. I want to show the assembly without the bore and then with the bore. I do not want to have to create a derived part. There should be a way of toggling this extrusion in the assembly view, but I have not yet found it.
In sketches i can see the names of the dimensions, the parameters, but if i have a few extrusions, can i know which parameter governs the height of the extrusion only according to their content?
All of a sudden, my line tool in sketch mode does not connect segment to segment and each individual line can be dragged wherever. This also means I cannot extrude any shapes I make because inventor does not realize the series of line segments create a closed shape. This happens across all part files, old and new.
I have been working on this project for awhile, trying to get it to extrude. The top drawing of the shape is when I created it, still as lines and arcs. The bottom pices are what I have broken it into and joined as polylines for extrusion. The top most piece of these is the one I have been working with, with no solution found. The 3 smallest of these pieces do extrude, but I need all of them to extrude as they are all different heights.
Once this extrusion problem is solved, the rest is just unioning it together and to the rest of my project. I have tried exploding them, overkilling them and joining them again, I have tried the boundary method I have found on forums, nothing is working. I have gone through with a fine tooth comb on the top most section and made sure there wasn't anything extra. I have tried using pedit on it, and many of the commands say you can't do this on a closed polyline. If its a closed polyline, why won't it extrude? I could find anywhere where it was "Self intersecting curves" like the error says when I try to extrude it.
We've got a lot of pipe added from CC then manually edited the extrusion length (D2) while modeling (not using tube and pipe). Now I want to get pipe lengths from the BOM. Currently the BOM gives the PL parameter as length, which is incorrect.
I know I can rename D2 and mark it as an exported parameter and add that to the BOM.
I think I could also make PL equal to D2 which would also solve the problem.
Both of these solutions would require opening and editing hundreds of parts, taking a LONG time.
We design long overland conveyors that can be kilometers long. In two separate instances, I have extruded a profile along a path that is a few hundred meters long with no problem. However, when the path gets to around 700 meters, the extrusion that worked fine at 600 meters simply falls apart. Does Inventor seriously have a limitation to length of an extrusion?
