I'm trying to use the surface offset command to create offsets of simple ruled surfaces. No offsets results and the command area reports that the ruled surface is invalid. However if I build the same surface using 4 lines (edge surf) then it will offset the resulting surface.
View 0 Repliesi need to create a solid by extruding/offseting a spline surface (attached picture). The problem is, a solid created by simply extruding this surface "outside" would cross itself, so autocad does not allow me to do it (neither extruding, surface offsetting is working) I tried to make a cube then using this surface as a splitting spline - however a solid created this way is flat on z-axis. How can I do this ? Everything is fine with the spline as well as a surface - it's closed one. Obviously the problem is in the fact in the self intersection of the extruded solid. So maybe using it to split a solid is a better approach?

View 9 Replies View RelatedI am trying to copy objects from an xref, and when I select the objects from the xref, they appear to the side of where they are actually located. So, effectively, if I want to place the objects in exactly the same spot where they are in the xref, I have to try and eyeball it, or take the additional step of moving them into place, which is becoming very time consuming.
View 8 Replies View RelatedAfter offsetting a profile line vertically, lets say minus 5 feet, for design purposes, is there a way to take that new polyline that is created and making it a polyline so it can be smoothed. Almost everytime, the enginner has asked me to smooth out that polyline that I have offset vertically, because it is now going to be used as a pipe in the final design. I have been drawing a polyline over the top of the profile line, so it looks smooth........

Currently, the only method that I know how to meet that 0.37" is by playing around (guess and check) with the number in picture 3. Any other methods to create this offset part.

I'm literaly just starting to use CAD so this might be a silly question, but how would I offset a line more than one distance in a command? Is there like a symbol you put between each distance like 2000;2250;2650 or something along those lines (no pun intended).
View 2 Replies View RelatedI'm trying to create a dynamic block for a schedule to satisfy an engineer's request. The intent is to insert this block with the text for the schedule, then array the rows for as many fixture type as we may need. Then copy the text down and edit as needed.
I've got the array set up, but when I drag the array, the first array increment shows up, but the row of the schedule does not. It is not until partway through the second increment that the row shows up, but it appears with a gap between the first and second row, so something is wrong with the offset or origin... I'm not sure.
On another post, distance needing to be set in the Array Action Properties and not just under the parameter. I don't understand where this is.
I have an autocad file with a simple rectangle in it.
The goal is to offset this rectangle 1" to the inside of the original rectangle, then delete the original rectange.
How could I go about this in autolisp??
I know I could use basic commands to bring up the offset functions, but i'm not too sure how i could write autolisp to offset in the correct direction, and the correctly delete the larger rectangle without deleting the smaller one as well.
Maybe put them on different layers? How I could achieve this?
Is there a way in CorelDRAW, that the resize option, the one we do by pulling all the arrows from the corners, offsets the objects equally. If I copy paste and resize the rectangle it does unequal offsets. I know the contour command, but is there any way to customize the resize command?

I often have to do storm pond surfaces that (for the purposes of planning) are flat on the bottom. These surfaces are created from a combination of survey data and grading groups and the tin of these surfaces is perfectably acceptable. However, when contours are shown, the flat bottom is shown with contours jig-jagging all over the place.
The attached image shows a comparison of the same pond. The top was created with survey data and grading groups; the bottom was created using contour data only. The generated surface on the top shows the bottom contour going in different directions and has parts where the an expected contour is missing.
How to correct/manipulate the surface to show a proper flat surface?
Has instances where you set your tolerance for the maximum triangle lenth to say 50m to reduce the amount of triangles along the edge that run at long distances. When I do this I end up with multiple surface holes and I'm not sure why as there are points in the area.
I thought well maybe it's because i should've reduced my max triangles first then added breaklines. Would this matter? I also thought I could add a line to the surface to fix the holes vs. deleting surface lines along the entire edge of a surface for many many miles.
I am trying to add points into a surface. I have done this before without any problems, but now I am having issues.
When I ID points which makes up the surface it gives me the correct Z level e.g. 24.5m, however when I hover over the surface it shows me the surface name and a different z level e.g. 0.65m. What is the reason for this difference in z levels? I think this may be causing the issue I am having when I add new points.
I select the surface and use the 'edit surface command' in the ribbon, choosing add point.
When I add a point at the level I require(23.89m), it puts it in a lot higher than the surrounding area, so I tried to put the point in to the lower z levels (0.4m) it puts it in a lot lower!
My goal is coming up with the volume bounded by the design surface and the existing surface. I don't have the design surface modeled yet.
Do i need to create alignment offsets?. Alignment 1 profile view is also attached. Then Alignment2.
What about starting with alignment1 profile view? Since I have created a polyline as the design profile ?
how do I shrink labels? Where is it in the settings ; the Align folder had been check.
I am issues with DEM files that I am downloading from the USGS website.I download 24k, elevation for the area I need. I then choose staged 1 second, add a surface to a blank drawing, then upload the DEM files to the surface.
The surface imports correcty, but when I try to import points taken by a surveyor on the same drawing, they plot incorrectly.The DEM surface and the points from the surveyor do not correspond. Also, the DEM surface is in meters, not feet. I have tried changing drawing settings, datum types, coordinate types, etc.
how I can add more volume to curved object surface? Say for example I have a plastic cup.You can think of this as cylinder object ,which was the shelled out using the shell tool and then had its base sealed.
Now at certain parts, I would like to increase the thickness and then blend it the rest of the surface(may be chamfer its edges) .
At certain parts on curved surface I would like to add an extra mm, I think if the surface was flat I would just sketch the shape, then extrude it by few mm and smooth the edges by doing a chamfer
But how can this be done on surface that is curved? Or multi curved for edges?
I would like to know how can put planar surface to solid object which surface is curved like cylinder for example. When start draw from first point rectangle of planar surface follow x cordinate not that solid object. How to do that simply?

I'm designing a press for a skateboard similar to: Rib Press
I have the board modeled: (see attached)
Now what i want to do is generate those ribs as seen in the picture.
I tried creating a block that intersected with the board and tried to split the rib at the surface, but to no avail. I think the issue has something to do with the curve of the board in two directions, but i can't seem to get it right.
if you are having trouble visualizing what i'm asking about, look at this. I want to be able to figure out the exact shape of those center ribs to print and eventually cut out of wood.
I have a project involving 3 programs. I am creating a planned development in 3d to be 3d printed when finished. The project is a 5 acre tract containing 8 buildings. I have built the surface in C3D and each building in Revit. The buildings are not in the same Revit file. For my solid work, I will bring the files over into 3ds Max Design to section into smaller quadrants to build in the 3d printer.
The questions:
Would it be better to import the surface into Revit to merge surface and buildings together?
Would it be better to import the buildings into C3D to merge entities?
Would it be better to bring those entities into 3ds Max and then merge them into one? Will 3ds Max Design allow me to insert entities accurately in the environment?
It is not possible forme to add the fil because it is to large 1.8MB how can I poste then I like to know if it is possible to extend the button flat surface diameter ø12.5 up to the shaped surface. The result should be a total solid block whit a surface shaped hole.

I need to create a sub-set surface from my main surface. not sure what the vernacular is for a "subset surface" in c3d but i do have a feature line that bouinds the desired area, but that is as far as i can solve.
i did try creating a new surface - pasted the main surface in the edit definition, then deleted triangles until the boundary alighned wiht my featureline. This seemed to work, but when i view the properties of the smaller subset suface, it shows a mimum and maximum elevation that is incorrect.
Im currently using an addon for Civil 3D called Novapoint. It allows me to create 3D models of surfaces made out of 3d faces and easily models cut and fill 3d-models for me.
The only thing i need to create a cut and fill model is one or several ground surfaces (existing ground, earth layers, rock etc. whatever i need) and a closed polyline/3Dpolyline that represents the level I want my cut and/or fill model.
I enter the spcifications I want such as; earth cut angle, rock cut angle, fill angle, select which surfaces i want to include in the model calculation and select the polyline.Novapoint then calculates the cut/fill model from the surfaces to the polyline and models the different cut/fill angles and gives me the results in a 3d-face model and a specification of the volyme of rock cut, earth cut an fill.
1. Novapoint is quite unstable and crashes alot
2. You cant create profiles out of 3d faces
3. Novapoint does not automaticly combine the start surfaces with the modeled cut/fill surface
4. A large surface made out of 3d-faces demands alot of computer power
So I want to how I do the same that Novapoint does for me in Civil 3D? (I have access to Civil 3D 2007-2013 depending on which one you're using)I know I can take the 3Dfaces i created in Novapoint and make a surface in Civil 3D with them but I want to exclude Novapoint completely.
all of a sudden whenever I run audit on my corridor file the surface definition becomes a snapshot. To add to the drama, the corridor surface will not paste into an empty surface. Why?
View 2 Replies View RelatedMy problem added with pic ... I want to make volume calculate for sample road project. When I try to compute materials I cant use Corridor surface for DATUM... There is only target surface on option..
View 2 Replies View RelatedI am trying to visualize a road project. The problems is, whenever the corridor surface goes below the EG surface (when the road is in cut) the EG surface is the only visible surface.
I sort of need to subtract the corridor surface from the EG surface, or merge the both surfaces into one.
If you look in the attached PDF, I have an elliptical wall that also has changes in elevation. call it a compound radius if you will. What I have to do is to make a wall cap to go on top of the wall. I know, sounds fun.....I have the surface on the right of the PDF and i need to figure out how i can take that shape and have it lay flat so that i can cut this shape out on my CNC. i know I can use the FLATSHOT command, but this will not give me the true shape of the board.
View 4 Replies View RelatedI was wondering if there is an easy way to trim one surface to another. Right now, I have two slopes (3:1) that are perpendicular to each other. They meet at a corner and I have extended them past each other so that I could see the intersecting edge. Now I would like to trim them to each other like you would a polyline etc... but I am not sure how to do this.
If I select surf trim, it tells me they are the wrong object type, but they are tin surfaces?
I know there is a procedure to turn a surface into a planar surface, but i don't really know if autocad can do that, or how to do it. By this procedure i mead transforming a cone into a surface, a cilinder into a surface for example, but in my case the main surface is not a basic surface (as show in the image) and the procedure is quite tricky.
