We have a custom-made sheet metal punch consisting of a 5x5 matrix of 1/8" holes. We export flat patterns from Inventor as DXFs.
We normally make DXFs by creating a view of the flat pattern on a blank IDW template (no border, no title block, nothing) and export that view as a DXF. This lets us orient the view at will, unlike right-clicking on the flat pattern in the browser and selecting Save Copy As.
When the sheet metal guy assigns tooling in his software, he needs to get each punch to "lock onto" the corresponding feature in the DXF. Normally this isn't a problem, but it has been with this gang punch. The center hole of the punch needs to lock onto the correct hole in the DXF, and it can't always seem to do it. I've sat alongside the guy as he does this, and in his software the centers of the circles show up as dots/points. But on this punch, there isn't necessarily a dot in the center of every circle, and it's possible that the center hole, which really needs the dot, won't have one.
I've come up with a workaround for this: a work point in the IPT. In the attached part, it's feature Tooling1. The sheet metal guy confirms that if I include the work point in the DXF as a point (in the AutoCAD sense), he can lock onto it. However, I find that if I generate a DXF from the flat-pattern IDW, the point is lost. If I generate an ACAD DWG from the IDW and save the DWG as a DXF, the point comes through in the DXF. But that's an extra step.
Is there a way to export directly from IDW to DXF and not lose the work point? Or is this as good as it gets?
For the sake of simplicity, the attached part has no bends. I realize that if I did, I'd have to re-create the points in the flat pattern, but that's another discussion.
For some reason it will not let me constrain a part to the center of gravity plains. I would like to constrain lifting lugs to the center of gravity so the model will automatically update itself. Is there anyway to make this work (using ilogic or anything)?
Why would Inventor tease me with showing me the center of gravity plains in an assembly but making them completely useless?
I know why you cant loop select and offset the rectangle but surley if you are going to take the time to listen to users and create requested tools, you should do it well?
View 4 Replies View RelatedCreate a Content Center Part that prompts for a file name and sets the Part Number to whatever I save the part as? It would also be nice to... Have the browser Display name the same as the saved filename.
If I have a standard part with a blank filename, inventor will make the part number equal the filename at the first save. It is this functionality that I require when using Custom Content parts.
E.G. If I have a length of 'RHS 200x100x6.3 - 2000mm' selected from content centre and I want the filename to be saved as 'Part-001', then I would like the Part Number to be set as 'Part-001'.
If I then place the same member in another project/assembly I may want to call it 'ProjectPart-100', where the part number would then be 'ProjectPart-100' and so on.
This method ignores the filename entry in the Ipart table.
In previous releases (2009 i think) when i converted a standard part to a sheet metal part i could recall all the sheet metal styles by linking back to the sheet metal template (i can't remember exactly how this was done, but it was possible with one operation)
In 2011 i canot find a quick way of doing this, it looks like i have to open the sheet metal template and export each different style (about 40 of them) and then import each one into the converted part. am i missing something? is there a simpler way similar to how it used to be done? Why have Autodesk made this more difficult?
As it stands at the moment it would be quicker for me to remodel the parts from scratch using the sheet metal template. I know this is the obvious solution, but seems strange to change something that worked well to something that doesn't!
I have tried just about everything and the mass properties center point of gravity is coming out incorrect.
I have created a box 300x300x300 with the center of the box at 0,0,0 (for testing the cg) . The result I get is not 0,0,0 one of the values always comes out to be not zero, depending on the orientation of the box. Is this a bug?
Dim cg As Point3d = T.MassProperties.CentroidMsgBox(cg.X & vbCr & cg.Y & vbCr & cg.Z)
how do I create this arc which does not have centre point co-ordinates . Also not able to use any of the arc or circle features to create this highlighted arc.

I'm using the Rotation tool to turn body parts around their usual connection points, moving the transform centre point each time. I'm wondering if it's possible to "lock" the centre point for any individual object to a certain offset from the object's actual centre, so that every time I reselect an object to move it I'm always rotating it around exactly the same place. I find that if I have to move the centre point from the real centre to where I want to rotate around every time, I'm not getting the exact same spot in relation to the object's bounds, which makes for some weird movements.
For example, the rectangle that makes up the upper arm should have its rotation point always about ten pixels down from the top and in the horizontal centre of the object. The elbow right at the top edge, but also in the horizontal centre, of the lower arm. etc.
I am assembling a weldment and need to place a looped bar onto a tubular stanchion 50mm below the top of the stanchion. I have made axis at each point on the stanchion and the bar, but i cant figure out how to constrain the loop to the point I require. All I can get it to do it to constrain to the centre of the stanchion only.

But when the "Convert to Sheet Metal" button is pressed, an error message pops up saying "This model cannot be converted to Sheet Metal because it contains features that have created multiple bodies. In order to convert to Sheet Metal these features must first be removed". The only way I can get this message to go away is to delete all the features. This part is used in a few weldments, so I'd rather not have to redraw it, but I'm at a loss as to why it can't be converted.

I would prefer to make this part with the Sheet Metal tools . How would this be made with sheet metal tools and how do i flatten this piece?
View 4 Replies View RelatedI just upgraded hardware and moved from Inventor 10 in XP 32 bit to Inventor 10 in Windows 7 64 bit. Previously I had an add-in that would place a work point at the CoG of a model. The new installation does not, and since I was not the original user of the old computer I don't know where it came from.
I'm assuming it was a 3rd party add-in or something that does not install automatically with the 2010 mechanical design suite (SDK tools maybe?). Any link or where to find this tool in the installed files.

View 5 Replies View RelatedIs there any way to locate exact center of a circle in after effects? I made a perfect circle in photo editing program and since layer's boundaries corresponded to circle's edges, i thought that anchor point in after effects will be exactly at the center. but it's not the case - the anchor point is at the center of a composition!
I imported the circle .psd layer together with other layers as a composition, does this have any importance? As i said,the circle layer boundaries corresond with circles edges, not with canvas' edges in my photo editing program. But whe i solo the circle layer, i see that the anchor point is at the center of a composition, not the layer.
So now i have to place anchor point at the center manualy, and it's pretty difficult to do it perfectly. when i rotate the circle, it wobbles and wobbles.
I am trying to link component parameters to the assembly and leader text always picks up the particular part in the assembly rather that the assembly as a whole. I want to point to a door assy with leader text and say it is "DOOR A" using model parameters but leader text picks up the particular part I am pointing to with my leader text rather then the assembly.

I would like to make the part named "Frame_base" an assembly on its own. see the attachment. I am new to Inventor and I thought I could demote it but the selection is grayed out. The main reason I want to do this is because I would like to create a 2D drawing of it with a parts list to give to the welder. This will be my first drawing and maybe I'm doing this wrong. It appears that I need to bring in the base view file, and I don't see a way to do that unless the frame is its own assembly.
Two IGES parts and try to convert them to a solid. I've tried all I can think of with no good result.
I can't get them uploaded, file is too large, what can I do?
I'm working on mating two assemblies together by work points on a part inside of them. Here is the code I'm using. It worked with work planes, but when repurposed it to work points, I get a type mismatch when the code tries to generate the work point proxies:
Dim oPartPoint1 As WorkPoint oPartPoint1 = oOcc1.Definition.WorkPoints.Item("botMatePoint") Dim oPartPoint2 As WorkPoint oPartPoint2 = oOcc2.Definition.WorkPoints.Item("matePoint") Dim oAsmPoint1 As WorkPointProxy oOcc1.CreateGeometryProxy(oPartPoint1, oAsmPoint1) Dim oAsmPoint2 As WorkPointProxy oOcc2.CreateGeometryProxy(oPartPoint2, oAsmPoint2)
The workpoint I have in my model is in the location I want.
When I INCLUDE it in my IDW file it shows up in the wrong location.
Glad I noticed that, I would have dimensioned to the wrong location and ended up with a scrapped part.
I wonder what would cause this? Maybe a bug? I looked at the model from every possible angle and the point is in the exact location I need.

I very often find that I would like to create a work plane defined by an axis and a point such that the plane is spanned by the point and the axis. But the only possible way seems to be to create a plane through the point and perpendicular to the axis.

View 3 Replies View RelatedUnfortunately, it's chock full of proprietary customer data, so I can't share the parts or the assembly. But I can pretty well explain what needs to happen, and I've attached a JPG that shows a bit of what I'm doing.
I need to design a bracket to hold an RPM sensor at a certain gap to a spiral bevel gear. I've got a huge assembly model (non-Inventor) from the customer, as well as the model for the sensor. My plan is to start a master IAM, insert the customer assembly, insert the sensor and constrain him, and draw the various hardware I need around the sensor.
So I start by making a work plane that matches the bevel angle and is in a location so the end of my sensor will be flush to that plane. Create a sketch on that plane, then project 2 relevant axes to create the appropriate "origin" from which my location will be based. Place a point on one line, at a certain radial distance and constrain my point.
So now I've got a point and a plane that are where I want my sensing face and my centerline axis to be. What now? I was thinking that I'd create a work axis "normal to plane through a point", but this workflow isn't available in the assembly environment. I can't constrain a solid to a sketch point, so I really don't know what to do at this point in order to put the part where I need it.
I am trying to convert a standard iPart to an iLogic based part. The part has some text driven, cells..PatNumber, Description..ect..But when I try to referance those cells the iLogic code either does nothing or errors out.
Basicly i have a bunch of flange rings with have several variables theat need to change as the part number changes, sounds simple right?I have rewritten the code so many times...I have gone from hunt and pecking to typing 300 words a min...well maybe not.
About 75-80% of all our parts are identical in shape but just get smaller or larger depending on what size portable auger it goes on.I have been trying to get the part to changed based on "PartNumber" but it has text in the value.
How do I delete work plane 1 from the attached part, 'test derived'?
workflow.
create a part, pattern a plane, save as 'test deriver'
create new part, derive work plane 1 from 'test deriver' sketch onto work plane 1, save as test derived
go back to 'test deriver, delete the pattern and create a new pattern, work plane 2, (i couldnt just edit it because the real life case was a series of patterns at different distances)
open part 'test derived', edit the derived part to include work plane 2, (work plane 1 doesnt exist in 'test deriver' anymore) redefine the sketch onto work plane 2
try to get rid of work plane 1 from the part?

I can obtain the Center of Gravity of a sub-assembly. What are the values with respect to? The origin/root of the whole assembly or the origin of the sub-assembly? How can I obtain the coordinate of the COG of a sub-assembly with respect to its origin or with respect to the whole assembly's origin?
