AutoCAD Inventor :: How To Offset Assembly Surfaces
Oct 11, 2012
I have an assembly that I am trying to offset surfaces from other components to create a different part. I have this part inserted into the assembly (only planes and axis exist on this part for now).
When I try to edit it in the assembly, and select "Copy Construction" from the surfaces menu it will not select the surfaces I need. First is this the correct command? This looked like the closest to an offset surface command.
If not, what is the correct command?
I should also add that this assembly has welds in it, if that makes any difference.

I want to be able to control the location/position of a component in an assembly. This is easy enough through the iProperties/Occurrence tab and then adjust the location of the X,Y, and Z offsets. Is this possible using iLogic? I have been unable to find a function to access via iLogic. Ultimately I am trying to translate a component about an axis not a pattern.

I have a BIG assembly with parts and surfaces. Of this I only need a relatively small cutout through the XY plane.
I tried extrude cut but that won't include the surfaces, and it will still calculate everything before the cut, right?

Using Parts created with "As Application surfaces" (only to aid positioning in assemblies). Main assembly built up from sub assemblies which include these parts have the issue on the displaye views in the drawing. When creating drawing views of the Main assembly the application surfaces cannot be hidden by deselecting the "Include All Surfaces" option on each assembly view.
They can be hidden as, shown with an assembly made up only of parts.

I designed a very straight forward piece of road consisting of a centreline, 2 channels and a footway either side. I played around with superelevation, assemblies and created a corridor. This all works fine.
Now when I add a taper to my offset alignments (for instance to widen the carriageway at a junction approach in order to add a splitter island), I noticed that the corridor stays perpendicular to the centreline. So this means the 2m wide footway I specified is not actually 2m wide, measured perpendicular from the curb. (See attached)
I have figured out that I can achieve this by attaching an offset assembly to the curb and attach the footway sub-assembly to the offset assembly. (So the curb acts a bit like a subsidiary string in MX). However, in order to make this work, I need to assign the horizontal alignment and Profile of the offset alignment to the Offset in the Corridor Properties Parameters (see attached). So far I have only managed to do this by creating a temporary surface which is wider than the curbs, so I can apply a profile to the offset alignment.
This seems a bit of a silly work around for such a standard simple highway design principle. Is there an easier way to create footways that are not perpendicular to the centreline?
Why is the superelevation I have assigned to the centreline, not projected onto the offset alignments? If this was the case, the offset alignments would have had a profile automatically?If you attach the offset assembly to the curb, why does it not automatically know it should stay attached to the curb? ie, remove the need to specify te horizontal alignment in Corridor Parameters?Is there a curb subassembly in existance that will project anything attached to it, perpendicular?

I have reason stumbled across the offset assembly functionality of corridors, and for the most part, I have been quite impressed. One thing that has come up that is odd to me that when I create a surface from the corridor using feature lines, the feature lines that are created by the offset assembly are not added to the corridor surface, even though they are visible and can be selected. When I create the corridor using links, everything is fine and the surface looks great. I can work using the links, but the more curious part of my nature is a bit tortured not knowing why this is happening.
On a related note, any strong preferences/reasons for using links vs. feature lines, or vice versa?

I've built a corridor using only an Offset Assembly. The assembly represents a new path alongside an existing road and I wanted to use the centerline of the road as the main baseline. I have successfully built the corridor and was able to build the Sample Line and Sample Views. However, I am not able to view the sections in the Section Editor. As soon as I try to get into the Section Editor, I get the error message "No station found". The stations are large, 500+00 and up, so I tried changing the BOP to 0+00, but that had no effect. I tend to think it's a result of not having any subassembly attached directly to the main alignment, only to offset alignments. I'm running the 2011 version.

i have a main control line and a offset alignment control line which have different profiles and superelevation. i know the offset alignment can apply profile but can the superelevation be different?

For some reason I cant seem to target an offset alignment layout profile with my corridor lane assembly. I can target the existing the existing groundprofile with the same offset alignment, but the layout profile when targetted does not change the lane in my cross sections. I can do this with civil 3d 2010, but not 2012. I have tried other lane sub-assemblies and it doesn't make a difference.

I'm looking for the best way to create a separate assembly out of various component parts in an existing assembly so that the whole thing can be placed in an assembly as you would a part, I know it's possible to demote components within an assembly but are there any other methods similar / better ?

We have an iLogic assembly with to parts in it. Maybe to cylindrical parts. The iLogic rules should do the following.
1. Start a Rule after open document.
2. This Rule starts a Rule in the first cylindrical component.
3. This Rule ask the user for a diameter.
4. The assembly gives this new parameter value to the second component
5. Then the assembly calls another rule in the second component to change it with the new parameter
Everything is working fine when the following combinations are taking place:
1. I open up the assembly out of vault or from a local drive or an accessible server drive
2. I insert the assembly as sub assembly in another assembly from a local drive or an accessible server drive
It don't work with the following situation:
- I insert the assembly as sub assembly in another assembly out of vault
Then the user becomes the dialog "Choose a diameter" twice.
I don't know why, but I have the idea it has something to do with the functionality of inventor to insert a component more than once. If you insert a component in an assembly Inventor gives you the opportunity to add more than one occurence after each other.
change that behaviour? Maybe a switch to change that inventor "add more than one occurence" behaviour.

I have encountered a problem with the Tube and Pipe styles.
As you can see, I have a rack assembly with a custom tube and pipe style. A wire as a tube in orange, and a tube support in white. Both have their seperate colorations at a style in the tube and pipe styles editor
When placing the rack assembly into the main assembly, it reverts to the coppor coloration I changed from the original style.
Steps I've taken:
Exported the styles .xml and Imported the styles into the master tubeandpipe.iam
Imported the user created .xml styles into the main assembly file nothing seems to work

I am trying to find the interior volume of an assembly (when am I not?!?!) by subtracting the assembly from a block that surrounds the most of it. Somewhere the assembly has a "leak" and I have been trying to use the Cross Section Analysis to track down where the inside lump is connected to the outside lump to be subtracted. Is there a less time consuming way to dynamically drag a plane across and get cross sectional views?
Even better is there a simple way to animate the analysis plane moving across the block so I can hopefully just watch and pause it when I find a leak?

it is possible to make a constraint that utilized a parameter of a part within the assembly.
For example, if I wanted to use the thickness of a plate, which I defined in the part, could I call that parameter in a constraint?

My assembly has grown (about 50 parts) to where I need to consolodate some parts into subassemblies for reuse and alternate iterations of the basic design.
When I import the original parts into a new assembly, all of the constrains I created are not there of course.
I've tried creating a new empty part and then deriving a new part from the assembly, but I can't add, delete or edit any parts.
I looked at using Shrinkwrap, Substitutes, iParts, Multi-body Parts, and Multiple Solids but I remain confused.
In retrospect, maybe I should have created the subassemblies between the part and assembly stage but I didn't.

I need an offset lisp routine to offset a selected line a set distance on each side of the selected line and change the layer of the offset lines to the current layer, and then keep prompting me to select the next line for offsetting until I'm finished.

I am trying to create a station-offset label style that will drop the trailing zeros in the offset section - e.g. 15' instead of 15.00', but if the offset is not at a whole number, e.g. 15.01, etc. it will display the entire offset.
I created two expressions: IF(OFFSET-TRUNC(OFFSET)=0,.1/12,.00000001/12)
and this one: IF(OFFSET-TRUNC(OFFSET)!=0,.1/12,.00000001/12)
I then created two offset components, one called truncated, and one called full, and assigned the heights to match the expressions.
I have attached the file, the style is ACHD-Sta Off-Rt [copy]

Can I select a bunch of parts in an assembly and say "save these pieces as a new assembly"?
It is just such a needed tool but I cant find an easy way to accomplish this.

I have a two part duct fire damper assembly. The IDW has the combined two part assembly, which I know how to turn the CoG on, so that it can be dimensioned. The problem is each piece will more than likely be hoisted separately so I would like to show the CoG for each piece, not the combined master assy.is there a way to do this?

How to get surfaces in a dwg to display correctly in inventor 2012? (just upgraded after SP1) I keep getting random results. I have a seat from our supplier translated from solid works brought in as a composite (converted in inventor 2011). I have assigned colors to faces and in the part/assembly environment it is fine, as soon as it is in a DWG it goes randomly transparent! Some times it is completely see through and others you get an odd face displaying correctly! Even in different views on the same sheet different faces appear normal.
Attached jpegs are: surfaces in dwg and surfaces in an assembly.

After you create a drawing view, surfaces can be included or excluded from drawing views. Files that contain only surfaces automatically include the surfaces in a drawing view. Is there a way to disable this functionality?

Working on a part and after much extruding and intersecting ended up with pretty much what I was after, but there are all these surfaces that don't seem to clean up by boolean operation of the solids. Will this cause a problem when I go to manufacture from STL file ?

I am attempting to revolve a sketch between two surfaces in Autodesk Inventor Professional 2012. The problem is that the extrusion is being created on the opposite side of the two surfaces that I want.
For example, I have two flanges on a cylinder. I would like the feature to be created to stretch on the lower side, the larger angle, where the sketch is. Instead, it is creating the feature on the upper side, the smaller angle.
I have adjusted everything I can within the revolve feature options, including unchecking "minimum solution" and switching the starting and terminating faces.
In the attached file I am attempting to revolve "Sketch 7" about the x-axis, between the two flanges closest to the "top." The sketch is centered on where I want the revolved feature to be created.

I would like to see if there is a routine that allows my iLogic code to detect if my assembly contains another assembly within it. If my assebly contains assemblies then I don't want "MyRule" to run. Else if it does then I want "MyRule" to run.

My Assembly has two possible positions for my piston.
I would like to show both piston positions (top and bottom) in one drawing file; however, in different drawing views.
I have tried using LOD and Drawing View Representations, but it is my understanding that neither of these are meant to be used in this way.

I am using 2013 and my construction surfaces keep displaying in my drawing views. They are hidden at part and assembly level and include surfaces is greyed out but they show as visible in the feature tree in the idw, and in the views.
Is there a setting somewhere to stop this. This is from IDW. They should not be visible.

I have successfully opened a STEP file from our Engineering group and saved it away as an Inventor Assembly. I would like to define Materials and/or Surface finishes for all parts. Why wouldn't the Surfaces and Materials synchronize between the Styudio's Surface Creator and the BOM Materials Control in the Assembly area?
I have found the way to define a new Surface in the "Inventor Studio" Interface and saved it with a unique name. Now, I would like to assign that Surface as a Material to the parts in the assembly ... and of course I would like to define numerous other surfaces and materials for assignment to all the parts throughout the assembly. Finally, I would like these surfaces / materials to follow the model into Showcase for presentation purposes.

Is it possible to show surfaces in a drawing view of an ipart member - although the option of include all surfaces is there I can't get them to show. Similar issue with showing sketches - get model sketches is there but nothing can be shown.

I've been doing a layout drawing of a plant
The floor of the plant is split into different faces to denote walkways etc.
When i saw they were missing from the drawing i thought it could be because i haven't 'included surfaces'.
I clicked on include surfaces on the model and it worked!
However, when the green arrow update finishes, they disappear, and the include all surfaces box is unticked! i didn't untick it, so what did?
