    Hello
    I have made a wood screw inside a project. Is it pssible to add a textbox with the woodscrew inwhere I can put the information about the dimensions of the woodscrew?

    The only way I know is to Dimension your drawing, then select one of the dimensions and change the text to suit.

    You're welcome.

    You may find this fun to watch and do.

    Yes, that is verry interesting.

    I think I have a verry steep learning curve here.

    Hello
    Is this the right way to dimension a 3d object?

    Need 3 planes top, bottom and front?

    Dimensions are usually drawn on a 2D sheet to be saved as a DXF file.

    The way DSM does this is by copying and moving the model into a Top, Front and Side Views. More views may be needed. As in First or Third angle projection.

    https://en.wikipedia.org/wiki/Multiview_projection#Third-angle_projection 

    The image shows Third angle projection.

    One other point. When you come to save as a DXF file, change the Display - Graphics - Hidden Line Removed. Also remember that the 'Annotations' will be in 'Raster Graphics' and may seem thicker than the models edges.

    Beautiful, nice and clean. Thats the way I wanna do it.
     
    I am gonna give it a try.

    Ok, I have done the dimensions on a simple Hem-Beam. Eport it to a dxf. When I open the dxf using an online vieuwer it doesnt show the dimensions. Do I need an add-on for this?

    Second, in a project, when do you start dimensioning. Say, I make a box with a lid and a holder. I have 1 object with 3 parts in it. Do I start dimensioning every time I have made a part or do I finish the object and then do the dimensioning.?

    I don't think that you have understood what I said.

    In your image you show two Annotation planes.

    You only need one Annotation plane. With at least 3 copies of your model, each one rotated to give a different view. Top, Front and Side. Then you Dimension on one Annotation plane. 

     

     

    As for exporting. What 'online viewer' did you use?

    When you create the Annotation plane make sure that you are in 'Plan' view of the plane when you save it as a DXF. Otherwise the Dimensions will not be saved with the drawing

    Don't forget a DXF file is only 2D.

    It may be best to download a free DXF program. I personally use NanoCad there are plenty more.

    In fact you could open the DXF file in any of these and dimension your model there.

     

    I would complete the model then copy and move/rotate the model as explained above then dimension it.

     

    The reason I state that you should change to 'Hidden Line Removed' is that the program will save all of the lines that are hidden, if you don't.  So if you wanted to use this for say a 'Laser' cut then each line will be cut. It will even cut the lines that you can not see. These will be cut on top of the already cut lines.

    Henk.

    What do you want the 'dimensioned design' for - what's it's purpose?

    2D DXF ( view straight on a plane / flat surface / annotation plane ) will accurately give you a file that can be used to manufacture the shape, perhaps on mill or a water jet cutting machine - DXF was / is the most simple form of data used in CAM  ( Computer Aided Manufacture ) programs - very simply 2D x,y coordinates.

    or, do you want a 'picture' of your design with dimensions on it , just to look at, show others etc. Perhaps in 3D as the 'I' Beam above or as a 2D picture, but looking like a normal 2D drawing.

    So, please confirm your purpose of adding dimensions - then we can advise the best method available within DSM.

    In essence, it is learning and understanding.
    I have always worked in the paper industry as a papermaker working on those big, big paper machines.

    Now unemployed I try to learn 3cad, maybe by making some Dutch tutorials so that others can learn from the mistakes I made and learning curve.

    For learning in design park I made a project "paper machine" because I know the way around these machines, the project is in the picture. A paper-machine has 3 basic parts, a wet part, a pressing part and a drying part.
    The photo shows the wet and press area. Slowly I am working on to the 3rd drying section part and for "understanding reasons" I want to dimension this.

    Here in the Northern Netherlands, we have many shipyards. I imagine a modern shipyard makes a 3D drawing of a ship and some parts of it are cut in a big waterjet or mill and other parts are used for commercial purposes.

    Hi Henk.

    Thanks for explaining.

    I've many things to say...

    Firstly DSM has been made from 'Spaceclaim' CAD technology ( now owned by ANSYS), in many aspects DSM (without buying additional modules) is only a subset of 'Spaceclaim' technology.

    Importantly, without the additional DSM 'Drawing Module', making 'drawings' of more than one view can only be (edit) 'rudimentary' done by the method Jacant outlined, i.e by manually making duplicates of the 'design' and manipulating each duplicate into it's own view orientation, then on a single annotation plane ( that equals a paper sheet), define the necessary dimensions. Much can accomplished but if needing 'professional' drawings at speed then this method compares poorly.

    Please watch this. ' https://www.youtube.com/watch?v=fd5MbU-f2tk '

    The example you show is known as 'Plant Layout'. With many parts , good 'Structure Tree' discipline will be very important - this will help in :

    Keeping file sizes as small as possible ( allowing easy on screen manipulation ).

    Easy selection of assemblies and it's child components for simple ( and foolproof ) manipulation of complex arrangements. I can explain more if you want .

    In your example of the Paper Mill machinery, perhaps a single plan view would suffice with the annotation plane on the 'ground' defining the x,y coordinates of the parts. Sizes of text ( double click to blue highlight ) can be changed and dimension arrows sizes are changed by selecting the dim, or dimension arms and changing the size in it's properties.

    As an example of adding dimensions, here i have used many planes. In DSM the annotation planes have to be under the file name - it seems they cannot be owned under an individual component. ;( ... the dimension layout to describe the design is your choice.

    I hope this 3D dimensioned view will give you ideas how to proceed.

     ...making 'drawings' of more than one view can only be very crudely done by the method Jacant outlined, i.e by making duplicates of the 'design' and manipulating each duplicate into it's own orientation..

    If you look very closely at the video of the Drawing Add-On Module. DSM uses three models all oriented correctly. Look at the Structure tree. This is all done automatically. I can still achieve the same effect, without the add-on

     

    ...I imagine a modern shipyard makes a 3D drawing of a ship and some parts of it are cut in a big waterjet or mill and other parts are used for commercial purposes....

    Going back to basic design, even ships were drawn in 2D.

    They basically had three views Front/Station view. Top/Plan view and Side/Profile view.

    They used concepts such as 'Stations' where the ship is split up into segments from fore to aft, usually where each 'Frame/Rib' is located. That would be the 'Side/Profile' view. Now looking at the 'Front/Station' view, each of  the 'Stations' the Cross Section' of each 'Frame/Rib' can be drawn and annotated. There are other lines that are drawn from the keel vertically up to the deck.

    Henk.

    it may be there in ver 4, but in ver 5 beta, i have just discovered that the properties of annotation planes, 'Outline' can be turned off as below for a clearer image.
