AutoCad 3D :: Gear Tooth Profile - Sweep Along Lines Shown
Jan 28, 2013
The attached file shows a gear tooth profile that I need to sweep along the lines shown. The problem is those lines are not all parallel to the UCS The tooth profile is a region.
Is there a workaround to make this happen? I used to do this all the time in 2008.
I couldn't attach the file 'cause it wss too big so I saved it as a PDF but now I can't attach that because it is not a DWG
I have generated a gear set using inventor. Now I would like to 3d print the gears. I have uesd the export tooth shape to get the true tooth profile. now I am attempting to use the coil feature to generate the helical tooth. The problem im running into is in the coil tool I can only give it a Revolution and height dimension. The hight is the width of the gear, but I am having a problem converting the helix angle to the "Revolution" perameter. I have read other posts and they say that it is Helix angle / 360. I have tried that and then compared it to the original gear generated by inventor and it is not even close. I need to do this on in internal gear and match it to an external gear.
I am drawing a gear and now i need to connect points to draw involute for a gear tooth: [URL] ...
Points are numbered. I'm trying to draw with a spline, but i don't know where to put last point of a spline to draw an exact involute - like for example - if i would draw like this and press enter - i would get this spline: [URL] ...
But if i would move cursor in a different direction and then press enter - i would still get almost identical spline, but still, not the same: [URL] ...
So how do i draw an accurate involute? Maybe i should draw one more point and then stop drawing spline?
I am attempting to creating a complex profile of a window frame using the Edit Profile command within Sweep. It tells me that lines cannot intersect. How can I draw more that just a simple rectangular profile?
Im creating a Profile Bandset and would like to have multiple surface/profile elevations shown, ie: EG, FG, Back of Curb and Back of walk. While creating this bandset I see that the text component editor properties only has code for profile 1 elevation and profile 2 elevation in the properties area, which the code for this looks like below.
Ive tried to write my own code using the profile 2 as an example but it doesnt seem to work as a 3rd surface/profile and only seems to mimic the profile 2 elevation when placed in the band
My questions are as follows
1) does Civil 3d only allow 2 surface elevations in any band set? if it does allow more profiles/surface elevations what am i missing to create it?
2) if Civil 3d does alow for multiple surfaces to be shown in the band set how do i get the text component editor to supply the extra profile elevation codes? or would i need to create from scratch
3) if i need to write the code from scratch does any listing of the codes and meanings of each code ie what does RN, Uft, Sn and so forth do and mean .
Attached are survey points that created the surface of a road embankment portion that caved-in. The road is very near a reservoir shoreline.
1. How can a surface profile be produce? I/'ve use line to change it into an alignement and then create a proile , then a profile view. But the the surface profile is missing.
2.the points having higher elevation are the top edge( road level) of the cave-n . A few few shots were take before the shorline elevations.
3. What the best way to come up with the rock volume to fill the cave-in given this surveying points., Also the shoreline elevation will be lowered some more while work is being done since the fill is not allowed to fall in the reservoir.
I am printing to a Brother laser printer and a Kodak inkjet using logos in a size I have never used before. None of the content is postscript, none of it should have halftone, and none of it is bitmap-based. I have resized simple CDR and AI vector line art logos for clothing care from large size (about 4") down to 0.25" for a project I am working on. Uniform fill in black is used and some of the logos have outlines and some do not. When I print the tiny logos on the laser printer, even with a DPI or 600 or 1200, some (not all) of the lines have a noticeable saw tooth appearance under magnification, instead of smooth. Fonts that are around 5-point print with clean lines. When I print on the inkjet printer with the same DPI settings, the logos appear smooth under magnification. There may be a hint of a saw tooth, but it is barely noticeable. Font that are around 5-point print with clean lines. Perhaps I went beyond the capabilities of the laser printer, but I question that because the fonts print cleanly with much finer lines than in the logos. Note that I did notice a 45 degree halftone appearance in laser printed text with a uniform fill that was much larger than the logos, even though it is not postscript. This did not occur with the inkjet.
how I can make these logos have crisp solid lines in the tiny size I am using? I'm not printing separations. I haven't found any settings in CorelDraw X5 to fix this.
I am having difficulty aligning the profile for a sweep feature. I need the profile to be normal to the path, but aligned vertically. In other words, the rectangular profile should remain "plumb" along the entire sweep. Is there a simple way to do this?
I have shared the sample files, trying to use the profile in two different ways, through Dropbox (they are too large to upload). I am using Inventor 2013.
I am trying to sweep a profile throughout the helical sweep path which is a series of 3d sketches. The sweet prifile sweeps correctly to the first 3d sketch profile but whin I select the second line the preview is gone and Inventor gives me an error saying the sweep cannot be done. how I can have the sweep done throughout the helical structure.Attached is the ipt file.
My purpose for Inventor (2012) is for cabinetry, more specifically the majority is for kitchen cabinetry.
All of our kitchens have crown, but not the same crown profile every time. There will be dozens of profiles if not reaching 100 or more.
What I am trying to accomplish is a way to model a sweep (which I can do no problem) but I would like to have the option of changing the sweep profile on the fly. I would be sitting with a customer and they would say "yes or no" to what they like.
I have looked at derived parts and iFeature and unless I am missing it, it's not giving me what I would like. Is this where iLogic comes in? How to use that, which I know I will have to eventually.
Right now I have an .ipt file with 7 crown profiles. Not sure I want to go any further for fear of re-work.
I am trying to perform a sweep of a profile and I am unable to select the profile. I have a part with a plane through the part. I created a profile on this plane that I want to sweep along my path. However whenever I try to select the profile I am unable to, even when I sectioned the part to the created plane.
I am working on Sweeping three helix profiles around a cylinder to create a screw thread. When I sweep the profile, Inventor gives me the error messages:
"The attempted operation would create a self-intersecting surfaces. Try with different inputs".
or
"The attempted operation did not produce meaningful intersection edges from the face-face intersection. Try with different inputs".
However, this is exactly what I need to create the helix profile I require and eventually increase the size of the Extrusion Sweep profile to 80mm. When I increase the sweep profile to 80mm I get the same error message about the self intersecting surfaces.
I am working with Autodesk Inventor Professional 2011, 64bit, 8gb RAM, Windows 7, Intel Core i7-2860QM.
I'm not able to get the right gear rotation in a planetary gear drive that I'm working on.
If I make the ring gear stationary and rotate the sun gear, the planetary gear engages and rotates around the ring gear
but in the opposite direction of what it should be turning. The planet to sun gear engagement rotates backwards regardless of what I do to the rotation constraint that I've applied.
If I make the ring gear free to rotate, and the planet gear stationary, the gear train rotates properly.
I've attached a mock up of the plant gear system to share and show what I'm dealing with.
Is it possible for a civil 3d structure to be displayed correctly in profile view when the alignment does not pass through the insertion point of the structure. See the attached screen capture.
The rectangular structure is a storage tank and there will be a pipe coming in on one end and the exit pipe will be on the adjacent side at the far end, just as the alignment shows - but the structure doesn't show correctly, or now how I expected.
dashed lines are showing as continuous in both model and paperspace the property tab shows the linetype as by layer when i click on the line and under the layers proper manager the linetype for the layer says dashed
I am currently using the visual style "Wireframe" and cannot seem to figure out why my lines won't plot out as dashed lines even though they are dashed in my layout. I have been playing around with my LTSCALE,PSLTSCALE but nothing seems to be working.
I just created a wall sweep on a wall , but I noticed the sweep doesn't adjust to the wall profile, please see the second floor wall in the attached image. Is there anyway to make the sweep adjust to the profile of the wall automatically?
I'm trying to create a Tiled Skirt (150x150mm) profile or pattern to be used as Wall Sweep. Is there anyway to create this profile as the Family Template: metric profile (wall hosted) only allow me to create a 2D profile.
I would prefer to avoid detail lines or Filled region to get the tiles shown as I need to schedule and quantify this element.
I am not able to convert a 2d gear to 3d gear . I have attached the 2d gear that i had created. I use Autocad student version 2012 . The gear is not getting converted into a complete solid on use of extrusion command . There are gaps in within the gear around the circle or something like that .
I have drawn figure1 with rectangle and press/pull command. I have drawn figure2 with line command. I want to trim the lines of figure1 which are shown in red color in figure2.How to do this?
I am attempting to model an internal 1/8"-27 NPT thread, both the through hole and the tapered part of the hole are modeled, but after I draw the helix and the polygon and orient the polygon to the helix correctly, (or even if I don't, I have tried it) it keeps saying unable to sweep object. I am using Sweep with Alignment with the No option. If I select the polygon first, then click sweep, it works, but rotates the polygon so that what I get ends up looking nothing like a thread profile.
I have tried reducing the polygon radius down to a ridiculously small value, thinking it might have been interference due to a possible trig miscalculation, but with no success, still have the same issue. FYI, I am using a .037" turn height for 27 TPI and a polygon radius of .0214", with a helix small end radius of .177" and large end radius of .189".
