Hi Dave, hi folks.

To avoid the problem of multiple images I choose the multi scenes skptutorial files.

This means that I have to upload only one file.

Just ideas.

Hi Thomthom, hi folks.

Is the fact that the large rectangle is a group can be the cause of the problem ?

I always though that, for an intersection to work, the cutting geometry must be in the context of the other object.

Maybe I missed something.

Hi Tig, hi folks.

Sorry for the error, I edited my previous post.

Thanks and best regards.

Hi rumcajs, hi folks.

In your post, you mention that you will look at the video when the time will come.

IMHO, this time has come.

I strongly advise you to look at all the beginner videos on SketchUp site and that you take the time to read the help about the tools on which you have questions. For example, the Move tool with its copying capabilities.

Believe me, the few hours that you will spend doing that, will be much less than the many hours that you will spend here, asking questions and discussing the received answers.

Hi rumcajs, hi folks.

The Point at centertool is available in SketchUp (SU) free as well as Pro.

To activate it, do this:

1 - Use Window menu --> Preferences --> Extensions. You will see many checkboxes in the rigth part of the dialog window. One of them in labeled Ruby Script Example. Click the check box to activate it. If it is activated, an X shows in the box. While at it, check all boxes to get all the tools.

2 - Exit the preferences.

3 - Close SU.

4 - Restart SU.

5 - Draw a circle.

6 - Right click the circumference of this circle to get a contextual menu.

7 - The last choice in this contextual menu reads Point at center. Choose it to get a guide point at the center of the circle.

This also works with polygons and arcs.

Hi folks.

If the bar between the 2 leg has a rectangular or square cross section, it can be done quickly. See attached SU file for ideas.

Elliptical truncated cone.skp

Hi folks.

Try using the midpoints of the horizontal segments between the two vertical lines to start and end the new vertical line. Zoom in if required to be able to get a snap to midpoint to work. This method implies these operations:

1 - Select the line tool .

2 - Zoom in on top part.

3 - Start the new line.

4 - Zoom out to see bottom part.

5 - Zoom in on bottom part.

6 - End the new line.

Another possibility:

1 - Click on left vertical line to select it.

2 - Click on Move Tool .

3 - Press the CTRL key to activate the copy mode.

4 - Move a copy on the right vertical line.

5 - Type /2 in the Measurement window.

You save one step and the process is probably faster that turning the roller on the mouse for the zoom in and zoom out and zoom in again as described in the first method.

Threaded rod approximation.skp

Bonjour.

Pour ce qui est de travailler en millimètres, pas de problème, je fais cela presque tous les jours. Mais c'est pour la conception de centrales hydro électriques. Les dimensions sont donc en millier et dizaine de milliers de millimètres. Règle générale, je n'utilise pas plus d'une décimale, donc le 10ème de mm.

Il faut garder en tête que SketchUp (SU) à été conçu à la base pour des travaux d'architecture. Donc, la modélisation de maison, édifices, etc., dont les dimensions sont de l'odre de quelques dizaines de mètres. Dès qu'on excède les limites, SU va avoir des problèmes. Pour les grandes dimensions, ça peut aller pour quelques kilomètres. Pour les petites dimensions, il faut se souvenir que toute face ayant une arête plus petite que 1 mm, ne sera pas formée automatiquement. Les outils Suivez-moi et les intersection sont capable de générer ce genre de facettes minuscules.

Pour arriver à modéliser de très grands objets, une planète par exemple, il faut utiliser un facteur d'échelle avant d'entrer les valeurs requises. Pour la Terre, par exemple, qui fait 12756 km de diamètre (12756000, je pourrai prendre un facteur d'échelle de 1/100000 et modéliser une sphère de 127,56 mètres.

Pour arriver à modéliser de très petits objets, on fait de même. Par exemple, un objet qui ferait 14 cm ou 140 mm pourrait être modélisé avec un facteur d'échelle de 1000. Il aurait alors une hauteur de 140 mètres. L'avantage avec ce facteur 1000 et le fait qu'on utilise le système métrique est qu'il n'y a qu'à utiliser le mètre comme unité de base et entrer toutes les valeurs en mm sans leur donner de suffixe. Comme cela, 140 sera interprété comme 140 m. Une fois L'objet redimensionné, cette valeur sera vue comme 140 mm.

Une fois terminé, il sera possible de redimensionner l'objet à sa vraie hauteur et les facettes fermées, aussi petites soient-elles, resteront fermées.

Dans le cas d'objets vraiment très très petits, il vaut mieux ne pas redimensionner car SU a quand même des limites si on va dans les microns ou les nanomètres.

Salutations.

Hi folks.

May I suggest the use of the most underused of SketchUp's menus, namely the Help Menu, the last one on the right.

The seond choice of this menu is the Help Center.

After choosing this item, you will arrive on the Help center main page here:

http://support.google.com/sketchup/?hl=en

If you look carefully at the left of the page, you will see a list of topics under a title that reads Get started.

The first choice reads: Learning SketchUp (a Trimble product)

If you click on it, you will get here:

http://support.google.com/sketchup/bin/answer.py?hl=en&answer=36207

If you read carefully, you will see the words Video tutorials formated as an hyperlink. If you click on it you will get here:

http://www.sketchup.com/intl/en/training/videos.html

You will be presented with five categories of video tutorials.

I leave it up to you to go each of these 61 tutorials. Of course, I suggest that you start with the first 28 dedicated to beginners before moving on to the ones addressing the more advaced users and then the experts. The last 2 categories are more for specialised modeling or presentation but are also interesting to watch.

Bonjour Pilou.

En utilisant le menu View --> Animations --> Settings pour changer les unités, tu va chercher le menu Model Infopar la porte d'en arrière.

La façon la plus rapide est d'utiliser le menu Window --> Model Info --> Units.

Note que l'autre méthode est la plus efficace pour changer les réglages des animations car elle ouvre la fenêtre Model Info avec l'option Animation déjà sélectionnée.

Hi folks.

With some simple geometry, it can be done with native tools.

Have you clicked in sequence on all the scene tabs that are on the top of the model window ?

Hi folks.

You can find endpoints easily if you can see them.

Use the styles to show endpoints.

Hi cgwar, hi folks.

Put the engineeringtoolbox.rb file in the following directory:

C:\Program Files\Google\Google SketchUp 8\Plugins

If your computer is a 64 bits machine, use this:

C:\Program Files (x86)\Google\Google SketchUp 8\Plugins

Restart SketchUp. The Engineering Toolboxchoice is to be found in the Plugins menu.

Hi folks.

Welcome.

Hi Daniel, hi folks.

try this site:

The Engineering ToolBox

Free tools and information for engineering and design of technical applications.

(www.engineeringtoolbox.com)

They have a plugin that you can install in SU and that will give you access to the site.

Even better, you can get a lot of components installed in your model directly from that site. Flanges are just an example of what you can get.
