  1. Hello all - I'm jim - New to forum, and auto cad. Over the last few weeks ive been using this site and others to learn AutoCad. I have gleaned lots of useful information however i'm struggling with UCS rotations/ Drawing 3D in a lsp. I'm half way through developing my first lsp that calculates the difference in X,Y,Y. It then draws lines showing deviation directions (for example deviation from design). X and Y devition lines seem to be working ( not fully tested negative coordinates yet) but I cannot resolve the Z line. I have highlighted area that is causing problems. and have attached a screen dump of current results. I know it is probably somthing simple I am missing, but I think i have been looking at the problem t0o long, with too much autocad inexperience If anyone has any ideas or pointers please let me know.

  2. I was hoping someone in the community could help me out. I've found a design for some 3D printed Mickey Ears that I really like that I'd like to import into Tinkercad. The problem is the file has too many pieces and Tinkercad won't import it because it's too complicated. I've tried to join in AutoCAD, but I'm a novice, and when I try, it finds errors and won't join everything into one, simpler, object. If anyone could give me some pointers or help me out, I'd really appreciate it. I've attached two files, one where I grouped all the objects, hoping it would then join (to no avail), and the other one is everything separate. Thanks in advance to any who could offer assistance. -Kent Blank Ear Grouped.dwg Blank Ear.dwg
  3. My company doesn't do much 3D, We would like to, we have the latest "Auto-CAD Architecture" and we primarily do kitchens and baths. Our typical presentations for clients consist of floor plans and elevations that we typical color w/ markers. It is a beautiful classic presentation. I'm looking for the best training options to learn how to create a plan like attached. The guy that can do this type of drawing is always busy and doesn't have a ton of time to teach it, and we don't utilize this type of drawing nearly enough. I want to learn how to do it quickly and efficiently to become a better asset to my company. where can i get some Kitchen 3d centric AutoCAD Architecture training. TIA

    Small 3D Trees

    Version 1.0.0

    56 downloads

    3D Trees (Deciduous and Coniferous) These 3D tree models are compatible AutoCAD R14 and higher. All drawings are suitable for use as blocks within AutoCAD. The trees have been drawn at an appropriate size for a young, standard tree, in metres. To insert a tree at the default size, simply use the default insert scale factor (1). You can always change the X,Y and Z scale factors later using the Properties command. The trees are all drawn on appropriate layers and are unique to each tree so that canopy colour can be changed independently when more than one tree symbol is used in the same drawing. In each case, the insert base point is at the base of the tree trunk in the centre of the tree.

    Advanced Model Assistance

    Good Morning all i am currently busy with a bridge for our structural department, and i need to model a Bridge End Block. i have attached a few images of the said End Block How would i go about modeling such an intense item ? The reason for the model rather than just linking in a CAD 2D view, is they require the End Block to be Reinforced..
  6. I'm having a hard time: I'm creating a middle line in the center of a road route, to verify the distance traveled by trucks. To do this, I create a 3dpolyline by connecting the edges of the path and then create a 3D POLYLINE by clicking on the midpoint of each polyline to draw a median route. As they are many, it is being a complicated job, since I have to click on the midpoint of each one to generate the 3D line that I need. Is there any lisp that can already do this, remembering that it needs to be 3D?
  7. Hi, Being new to this forum, I have first tried the search option to look for similar problem which I couldn't. Problem: Panning in Top, Left or any other Orthographic View, shows the hidden or out plane details. Please see in this figure. This is a circle extruded to height of 45ft and I panned in the TOP View to the right This is when I panned it to upper left corner. Desired Output: I just want it to be panned as in true Orthographic Projection. As shown in the figure below. Thanks.
