Recently have had AutoCAD re installed and and am having trouble unioning and subtracting the two solids in the attached file. Other objects will occasionally subtract and union with these objects, but only occasionally.
View 4 RepliesFAIL-UNION-3D-Polyline based wedge.dwg...An unusual bug here, and a workaround of sorts. This one is fairly serious and results from attempting a union of a solid with another solid, when one of the solids is created entirely from 3D polylines and is not on a CCS planar axis.
I'll attach the same file twice - once with a bug ( 3D polyline solid ) and once without the bug ( Solid has been modified to include one "normal" polyline face.
In the middle, a wedge connects the two. Basically, I needed to increase the angle between them by 15 degrees, so slice, polyline around faces and LOFT. Pretty simple and straight forward. The result was that any attempt of a union with the wedge in the middle results in a failure due to inconsistent faces, and the deletion of the non-polyline solid.
This results in damage to the file, and the operation must be backed out or reloaded.If the middle solid includes ONE normal polyline face, with a repositioned CCS on the face, then no problem. This is a workaround, but only sometimes, however if fixes the problem for both the polyline face and the 3D polyline face.
I've encountered this problem a few times, but it was this project that made it possible to capture it cleanly and understand what was happening. It's a critical bug, but only affects parts made from 3D polylines and LOFT operation, so it's more likely to affect complicated designs.
To see problem, take 3D polyline file and use SOLID UNION on the three ( or middle and one side ) pieces and you'll get an error and part deletion. Try again with the "workaround" file, and you'll see that it works both sides now.
The file with this post is the "broken" one - the middle wedge is a single 3D solid created with LOFT and 3D Polylines.
Where I am joining 2 solids (like plywood sitting in a dado joint), how can I have one solid be carved out where the 2nd solid overlaps it, without deleting the 2nd solid.
what SUBTRACT does but without the deleting.
I have created the attached wheel drawing using the Revolve command.
You will see one cylinder solid thru the wheel on the attached drawing file.
I am trying to use the Subtract command to remove a hole space thru the wheel. Can't get that to work.
I have inventor 2012 and I´m having trouble doing a cut boolean operation to two solids. One is a revolved elipse, so it´s a kind of egg, and the other one is an extruded rectangle.
I want to cut the egg in the rectangular solid, so I can obtain a rectangular solid with an empty egg space inside. I tried to use the "derived" command, so I derived the egg from the rectangular solid, and used the combine command, but with no success. Right now I have two separated solids on the same file (the egg and the extruded rectangle).
what's the best way to subtract one solid from another then turn the remainder into multiple solids?
View 1 Replies View RelatedI am in the 3d modeling view, and have extruded closed polylines. when i go to subtract the object inside the other it won't subtract the command says <Modeling Operation Error: failure in face-face intersection merging algorithm>
I don't know how to fix it.
I have a base(blue) with an array(orange) positioned on a face.
When I select all & UNION the whole geometry becomes orange & I would like it to become blue.Selecting the base first then the array doesn't seem to work.
union the red and yellow objects? after that in mine I have intersection line between them! why?and the other question is; when I try Interfere command to remove the interference object it doesn't work!
View 6 Replies View RelatedI was wondering if you have to solid objects and then use UNION command to make them as ONE object BUT then I don´t after a while you realise that this was a mistake is there a command that you can use to split them as they were before (beside from command undo or slice).

I have tried putting a flag behind text and trimming so it only shows through the text but not only does trim not work, I cant seem to get a transparent fill for the text anyway. Ive seen an example of transparent text but no instructions as to how to do it.
Whenever I try to union two solid objects, there is a line between the two objects even after they are in union. How can I avoid the line?

I have created an object and unioned it with another object of what i assumed was the same length.
These nasty lines appeared and as i zoomed in an unwanted face appeared.
I have tried solid edit and delete face but it says gap cannot be filled. There is another unwanted face i am assuming on the other side but the gap is so small my computer always freezes and slows down before i can get in that close to examine it.

View 9 Replies View RelatedI've tried using the union tool in AutoCAD 2013 as well as the Boolean join function in Inventor Fusion 2013. In AutoCAD it doesn't let me select more than one object (says that the array is the only object and that individual unit blocks are duplicates). In Inventor Fusion I can't seem to get the hand of selecting the target & tool bodies.

View 9 Replies View RelatedI have a solid of a vortex breaker for a nozzle in a cone, from which I subtracted the cone. But when I attempt to subtract the nozzle as well, it will not subtract. I have verified that both entities are solids. I copied them into a new drawing by themselves. I even rebooted my computer--all to no avail. I have attatched a drawing of the two solids.

I am in need of subtracting Surface A from Surface B to display the surface intersections between the two. I have a geological top of clay surface and a bottom of clay surface where the bottom intersects with the top thus showing holes in a geological clay layer. I am wanting to know if Civil 3D supports the subtracting of two surfaces.
View 6 Replies View RelatedI have two boxes stacked on top of each other. On the top I have a rectangle which I want to extrude down through the first box and partially through the second box and then subtract the extruded rectangle from the two stacked boxes. Extrude works fine, but when I use subtract it only removes the area from the first box. The bottom box remains solid despite having "extruded" the rectangle down through the bottom box as well.
I've tried joining the two boxes into a single object before using extrude and subtract, but for some reason the join command won't work in this case.
I've got four objects. One of these objects is a cylinder. I want to remove some material from the cylinder. The material which I want to remove is specified by the other three objects.
Basically:

I am now modeling elements for silicone formwork for casting elements of epoxy resien.
I would like to schow idea of this formwork. For this I would like to make part representing silicone part of this formwork. It is contained in aluminium "cover" for convenience of use.
In assembly I have placed may model, and aluminium elements representing "cover" of formwork.
I am trying now to model silicon but it is quite hard. I can not use "derivered part" method to substract model and cover elements from some big block body because coordinate systems do not mach in all elements.
In Part there is "combine" function but it only works with bodies mabe within this part.
Is it possible to substract one placed in assembly from anothe part in this assemby?
I would like to be able to extrude an object then do a subtract or something similer, then somehow put the subtract on a layer so if i hide said layer the extrueded object will be showen as if it never had the subtract applyed. But if the layer is show agean then the extrued will have a hole in it agean.
P.s. for an example of one thing this could be used for, modeling wrenches with difrent shaped grips but the same handle. Without just making multiple copys of the handle.
