Removing the revolving lines and creating a technical draw

[Mr.Mike]

is there a way of removing the revolving lines of a cylinder? I've created an object based on a cylinder, then i tried to see the object in the layout using the MVIEW command and then choose a viewpoint to each window that appear. For example i chose a view from 1,0,0 in one window, but the fact is that the dimensions of the projected cylinder don't match the real diameter in 3D. I believe it's because of the isolines, although i've reduced them to 2 and nothing changes. The outside distance between the outside lines of the projected cylinder doesn't match the diameter in 3D, maybe because those lines aren't in fact outside lines. I could use some help tranforming a 3D draw in a technical draw with 3 projections from 1,0,0 ; 0,1,0 and 0,0,1. Many thanks

read up on the DISPSILH variable.

if your dimensions don't match... are you trying to dimension in paperspace ?

[Mr.Mike]

Thanks for the command, although the value was 0! Probably i'm making a mistake drawing my 2D draw (paperspace) from the object, is there any chance you could explain to me the simplest way? Many thanks again hendie

If I am reading this right... You are trying to take 2-d shots of a 3-d element and throw them into layouts in paperspace? Is this correct?

I hope I am not too far off, but I have never had the problem you are talking about. If what I said above is true and you are trying to make TRUE 2-d shots then SOLVIEW AND SOLDRAW, SILDISP AND HIDE PLOT ARE YOUR BEST FRIEND EVER...LOL

If this is what you are trying, then the following steps may just help you out some!


Solview made easy!

These are the steps I use for this process... works great for me anyway..


This will establish the UCS or base starting point, which all the view ports will be projected from.

STEP 1
· In model space, convert to single view port and change to top view.
· Go to layout and delete the current view port.
· Type in SOLVIEW, hit enter
· Type U, enter
· Type C, enter
· Type 1, enter
· Specify centre of view port
· Enter
· Specify size of view port by selecting upper left corner and create a rectangle a little less than ¼ the size of the sheet.
· Enter name of view port.
· Exit the command by hitting escape or enter and then resize the view port to fit in the upper left hand corner to give you room to project the new view ports.

Now go ahead and use the SOILVIEW command again to project the new view ports from the established UCS view port.

STEP 2
· Type in SOLVIEW, hit enter
· Type O, enter
· Select side of UCS view port to project from
· Enter
· Specify centre of view port
· Enter
· Specify size of view port by creating a rectangle a little less than ¼ the size of the sheet roughly where you want the new view port to appear..
· Enter name of view port.
· Repeat step 2 to insert the amount of view ports desired.

Exit the command by hitting escape or enter.

STEP 3

· Type SOLDRAW, enter
· Select all view ports
· Hidden lines need to be defined.
· In layers chose the hidden lines in the appropriate layout layers and load up the type of hidden lines desired.
· Regen all. Hidden lines should be visible, if not you may have to change your LTS.

STEP 4
· Type DISPSILH
· Enter new value = 1


HTH... If not I apologize for the lengthy post!

Set "dispsilh" to number 1.
Also, you can't get true dimensions in your layout if you are dimensioning an isometric or perspective view. You need to be "normal" (perpendicular) to what you are dimensioning for it to be correct. This is assuming that your xp-scale factors are correct.

I believe i've already discovered my mistake... The problema was that i've been rotating my object, so the isolines have changed their position. When i was trying to project from one view, as they weren't in their position, the whole draw was messes up.
Just another question, i've created an helix in my object, is there any way of removing the lines of extrusion of the helix, leaving only the outside lines? Many thanks for the help!

[Mr.Mike]

Thanks for the help! Eitherway, i found myself with another problem! I've already defined the type of lines in the hidden lines layer but nothing changes! LTS was set to 1. I changed to 0.5 but still the same! I even tried to draw a simple line in the hidden line layer, defined that line as the hidden line type and it appears as continuous! Can't anyone help me?

PSLTSCALE ?This will change how the linetype is viewed in relation to model/paper space.Click

[Mr.Mike]

PSLTSCALE seems to work on lineweight but not on line type, either way i think that it will do for me. One more, and i believe that it's the last question for now, is there any way to make the viewport outside lines invisible when plotting? Thanks hyposmurf! :D

[hyposmurf]

Try a regen afterwards,or just change the PSLTSCALE again and you will see a difference,well hopefully!

We are here to serve you :D


is there any way to make the viewport outside lines invisible when plotting?Place it on a separate layer. In the Layer manager set it to don't plot.
