AutoCAD Inventor :: How To Interact With Source Code Of LOFT Command
Jul 6, 2012
How can i interact with the source code of LOFT command.Especially, I'd like to inform me, about the method that Loft commad uses in order to draw a solid. I suppose that the two sketches I want to intersect, are close enough, thus the programm, can't generate the geometry...
I am following the U-Tube exercise called "Emergency Light (Cabinet) volume 1". I am at time stamp 1 hour 26 minutes, exactly.
In the video they use a Loft command in order to cut a shape out of two sketches numbered 10 & 11. I have been copying exactly and am having difficulty at this stage of the model.
Is there any reason why I am managing to use the Loft command earlier perfectly but not at this point.
Attached is a zip file with the source code I used to modify the Parcel Map Check Report, as discussed HERE. It is essentially the code as provided with C3D2009, modified to reduce the amount of paper required to print them out. There are some other optimizations (allow sorting by columns is one), but this was mostly done a few years ago and I do not recall everything I may have done. Projects included for C3D versions 2010-2012.
Is it possible to have a look at the sourcecode oft Paint? I am having trouble with a Nikon Coolscan IV Scanner. I am using at the moment twaindotnet. Do you have a better library?
I have a bunch of points that I am trying to turn into a solid object. I am doing this by using the 3D poly command and then LOFT, UNION and CONVTOSOLID. this has previously worked well, but this time when I use the LOFT command it does not produce a 'closed' surface, but rather a grid like surface which wont convert to a solid. Are there different settings for the LOFT command, and if so, How do I change them to produce a closed surface?
I am trying to loft 4 circles onto a straight path it seems as if they are turning somewhere in the middle, and the shape ends up looking like several 8:s stacked on top of each other instead of the cone-like shape I'm after.
I've tried aligning the first vertices with the "make first" command, but it didn't work. If I go to subobject level of the lofted object and choose Shape > Compare (as I read in some thread I should..), the pop-up window shows nothing (blank, with the pointer in the middle, doesn't matter how much I zoom).
There is a major bug with CorelCAD LOFT command - when used with 3D polyline objects, it fails and errors out with the following error:
Specify cross-sections in lofting order»1 found, 2 totalSpecify cross-sections in lofting order»Selected cross-section is not a valid type.
The workaround is to set the CCS to the plane of the 3D polyline object and then use 2D polylines to recreate it, move the 2D version, delete the 3D version, Align the 2D version with where the 3D version came from and then repeat the LOFT command.
Has been logged with Graebert under ticket: #12458
To repeat the error, see the test file. There are two radially aligned triangles in each set. The set on the left are 3D polyline. The set on the right are 2D polyline. Attempting to loft the set on the left will cause the error.
Both large and small triangles are respectively co-planar.
I am having multiple problems creating a loft. Firstly, it seems as if the "loft" command remembers and uses history of the objects to be lofted, which in my case meant that instead of lofting the scaled down (correct) version of a shape, it insisted on lofting the former, out-of-scale version. It would be great to know if there's a more conveniant workaround to this than redrawing the shapes (as I ended up doing).
Secondly - and this is where I'm stuck now - 3ds will not let me do a loft with the new, redrawn shapes. The loft accepts two of the shapes, but will not let me select the remaining three, claiming that "the shape has a different number of curves than others in the Loft". My question is thus: What should I do to be able to see and edit the number of curves in the shape, so that my Loft will be valid?
I'm going to be creating a 3d visualization for an existing network of gold mining tunnels and ore veins. What I have are scans of 2d hand drawn pages showing mining tunnels and ore veins. There are a couple hundred of these, each representing a 100' thick slice which get progreessively deeper. My intent is to trace these in autocad and stack them up, create solids, import them into 3ds max. One issue is that the ore veins are in some cases continuous from level to level so I'm thinking of using polylines and the loft command to connect the veins between levels.
how to model this efficiently so the import into 3ds max goes smoothly. Or is there an easier way than the acad loft command to model the veins within 3DSMax?
I'm trying to change the dafault varible for the mirror command from no to yes. whne you do the mirror command after you choose your second point it asks if you want to erase the source object and the default is set to no but I would like to change it to yes. I'm able to change the macro for the mirror button which works but only when I push the button. Before the cui file I remember everything was done from the acad.pgp or the acad.mnu files but with the new CUI file i can't seem to locate wher to change the actual command and not just the macro for the mirror button.
I recently switched from LDD to Civil 3D 2010 and have since had problems with the command line recognizing Alt Codes when entering leader text. After the leader command is finalized, I am able to edit the MTEXT which does recognize the alt codes. I use alt codes for various symbols and now have to edit leader MTEXT each time in order for the symbols to be recognized. Is there a toggle or some other setting in later versions of AutoCAD that would allow recognition of alt codes at the command line?
i have problem with vba sendcommand method, which i use to send publish command. vba code doesn't wait to finish this command, but continues. i need to wait for finish publishing and then continue.
I need to shell out a Loft in the attached IV 2012 part file.The Loft i tried also as a new solid but the shell also cuts into the cylinder ( revolution 1 ) . I only want the 2 sides and bottom of the Loft to be Shelled, not the cylinder. What do i need to change to get the shell to work?
I'm loft retarded. What I did here was loft to a tangent work plane, then did a sketch on the top surface and extruded the shape that I want. There has to be a better & easier way.
I have a cylinder on top of a curved surface; I want to make the cylinder land adaptively to the surface, so I projected the circular face of the cylinder in the surface, which ended up being a 3D sketch. I tried to loft a solid between both curves, but it always gives me errors. Some examples are:The attempted operation did not produce a meaningful result. Try with different inputs.Multiple disjoint loops found in a profile section.
I have had success when trying to do the same thing with curved surfaces in two dimensions only (e.g. extruding a 2D curve), but I think the error is produced since the curved face I am trying to use belongs to an elipsiod.
Okay I've been building random things to teach myself how to use Inventor and right now I'm stuck on a rim I'm creating. My question is.. is there a way to copy and paste a lofted item since there are three parts to it (2 planes and 1 guide) because I need 4 more spokes and if I copy the loft it copies all three parts seperately. Then when I paste and orientate the small end of the loft to the plane I want it tells me "Unsatisfied Geometric Inputs".
I am having trouble trying to get the Loft-1 to run the same shape as Revolution-2 .Picture 1-1 shows how Loft-1 is slightly off centre to Revolution-2 at the top .could i model the Loft-1 and Revolution-2 using different tools in one command making it a smooth shape. Another problem i have is how do i make Revolution-2 at the end terminate into Revolution-1 smoothly.I tried using Loft but it kept getting fail message.Picture 1-2 shows where to terminate the end into the Revolution-1 body.
I have created a loft from 4 different sketches. Now I want to make a drawing with the front, side view and the dimensions of the 4 profile sketches from the loft. But I can’t find a way to put the sketches from the part on my paper. It works with copy-paste ;^) but this is not the way I want it (it’ll not change when I change the profiles in the part).
Using the image below, I want to removed the yellow extrusion up to the red circular edge, I assumed split tool would do this.
And I don't require this but i would like to show the splines on the ends to "feather" out to the round like the actual axle does. (this is just for aesthics) I have the extrusion done, But I can't figure out feature is requied to do this, loft?
I have a part that I'm trying to loft using 3d sketches for the rails will this work? Everything is fine till I try to add the rails, As you can see the loft works with out the rails.
