How to get Dimension call out on thin piece

    Select the face of the object you want to dimension, then pick the 'Dimension' tool. A new 'Annotation Plane' will be created on that face. The same on any other face that needs a dimension. You can have as many as are needed.

    You will notice in the Structure tree the Annotation plane is Bold indicating that it is 'Active'

    If you 'Select' any of the Annotation planes and pick it's 'Properties'. The outline of it can be changed to 'No Outline'

    You may find this helpful.

    Hi Rob,

    Thank-you for responding.

    After much experimenting, I am still completely lost.

    Yes I see that the Annotation plane is Bold.

    When you say, Select the plane and pick it's properties, I'm really not clear on what you mean:

    -- I tried selecting in the Structure tree item

    -- I tried selecting the "plane"outline in the drawing

    -- I tried selecting the face of the edge of the object

    Regardless of which of the above 3 I try, when I right-click and then select Properties, nothing happens ... as far as I can tell there are no pop-up dialogs, or text or options appearing anywhere else on the DSMech dialog.

    When I drag from any part of the edges of the face I always get the wrong dimension. I am trying to get the thickness.

    Again, my piece is 4 x 6 x 0.25 and I am trying to get the 0.25 dimension to show.

    Thanks again.

    Any other tips are very much appreciated,

    To reiterate.

    Select the face you want to dimension, then pick the 'Dimension' tool. A new 'Annotation ' plane will be created it will show up Bold in the Structure tree.

    If you want to hide the edges of any Annotation plane, select it then go to the 'Properties' tab - Appearance.

    All 'Docking Layouts' can be changed.. As seen in the image. I have dragged the Layers tab and the Properties tab over to the right hand side of the screen and used the 'Auto Hide' pin.

    Just drag the Name of the Tab. it will become free and can be placed anywhere, or use the images that appear to locate it to an edge. You can then use the 'Pin' to 'Auto hide' them.

    Goto File - Designspark Options - Appearance to Reset Docking Layout, if you are not happy with the result.

    Hi Rob,

    I do appreciate your continued efforts.

    I am sure I will get this working if I just try enough approaches.

    Right now, I am unable to try your new suggestions because various unexpected things are happening:

    -- the sketch plane rotates itself 90 deg

    -- some objects that were "drawn out" in the 3D view are now flat in the 3D view

    -- I get locked into the 3D view, i,e, the Plan View is greyed out.

    -- some of the objects I drew and had dimensioning lines have shrunken in size and no longer reach to the extent that the dimensioning line is calling for

    I guess I will start all over again and not be so ambitious at first and see if I can draw all the items that I need in the Plan view before going into the 3D view so it won't matter if I cannot get back to the Plan view.

    I do appreciate your willingness to help. I have watched many vids on youtube and will listen to a few more.

    All the best to you. Thanks again.

    From what you say you are going into 2D Mode with a New Sketch plane showing. Parts of the model will be greyed out and the new Sketch plane will move to the face you picked.

    To Dimension you need to be in 3D Mode. No Sketch plane in view. So to dimension an edge of your model you must create a new annotation plane flat to that surface. You can select the Dimension tool first then move the cursor to the face you want to dimension. A New annotation plane will be created. If you are already using the Dimension tool you must use the 'Escape key' then select the Dimension tool again, otherwise you will still be using the Active annotation plane.

    Dimensions are usually there to portray the sizes of an object in 2D with a top, front and side view.  Known as 'Orthographic projection'. 1st or 3rd angle. 

    If you wanted a true Orthographic projection. The only way to do it is to make the model into a 'Component' then copy the model three times and 'Rotate and 'Move' them into the correct position. With a Top, Front and Side showing in a 'Plan' view. Then all Dimensions can be in the Plan view, with only one Annotation plane. Any alteration to the model will update on each of the copies. These 'copies' can be hidden if needed.

    You will note that although the Annotation plane is on the surface of the 'Top', edges and surfaces can be picked above or below this.

    Interestingly, that is how the 'Add on Module' works.

    Here I have 'Moved' the Annotation plane up to the axis of the hole. Then picked the 'Section Mode'. All References to the dimensions are still intact.

    Thanks Rob,

    You really are the Greatest.

    I have it ALL WORKING now.

    The simple mechanism of the "last selected plane" in the 3D view being the reference point for the Plan View was completely escaping me.

    I kept getting different Plan Views (when it was not locked out) and was unaware of the reason.

    I will continue to study your posts because there is a variety of other info in there that I want to own.

    I am an EE, so mechanical drawing is not my highest forte. I use DSpcb extensively. Very nice package indeed.

    Again, thank-you. I am generally pursuing designing packaging for electronics and having that manufactured, either traditionally (CNC) or through the new "printing" regime. Some of my needs are for simple enclosures, but also there can be a variety of plastic or metal accessories, fixtures, etc associated with antennas, adapters, holders, etc and I think DSmech might fit the bill. At some point when my proposals are funded, I will hire mechanical engineers and mechanical drafters to pursue this work, but right now, I am a one man army.

    Happy New Year. All the Best to You and Yours! Thank-you again.
